Question 1
Correct
-
A 35-year-old man visits his GP complaining of nasal congestion, facial pain, a runny nose, and a decreased sense of smell that has been ongoing for three months. He has a history of seasonal allergies. Upon palpation of the maxillofacial area, tenderness is noted. No visible nasal polyps are present.
What are the primary symptoms of chronic sinusitis?Your Answer: Facial pain and/or pressure
Explanation:Understanding the Symptoms of Chronic Rhinosinusitis
Chronic rhinosinusitis is a condition characterized by inflammation of the sinuses that lasts for at least 12 weeks. To diagnose this condition, doctors look for specific symptoms that are indicative of chronic sinusitis. These symptoms include nasal obstruction, nasal discharge, facial pain and pressure, and loss of smell sensation.
Facial pain and pressure are common symptoms of chronic sinusitis, and they are caused by congestion of the sinuses. Pain is typically felt over the maxillary, ethmoid, and frontal sinuses, which can be palpated by a doctor during an examination. Coughing is not a major symptom of chronic sinusitis, but it may be present in some patients and could indicate an underlying condition such as asthma or COPD.
Nasal polyps are not a major symptom of chronic sinusitis, but they can be present in some individuals with this condition. The presence of nasal polyps indicates a variant of chronic sinusitis, which may require different management strategies.
It is important to note that symptoms must last for at least 12 weeks without resolution before a diagnosis of chronic rhinosinusitis can be made. If symptoms last for less than 12 weeks, the criteria for chronic rhinosinusitis are not met. While patients may be experiencing chronic sinusitis before the 12-week mark, doctors must wait for this duration to confirm the diagnosis.

You assess a 24-year-old female patient who complains of bilateral nasal obstruction, nocturnal cough, and clear nasal discharge for the past three weeks. She reports experiencing similar symptoms around the same time last year and has a medical history of asthma. What is the probable diagnosis?
Your Answer: Allergic rhinitis
Explanation:Understanding Allergic Rhinitis
Allergic rhinitis is a condition that causes inflammation in the nose due to sensitivity to allergens such as dust mites, grass, tree, and weed pollens. It can be classified into seasonal, perennial, or occupational, depending on the timing and cause of symptoms. Seasonal rhinitis, which occurs due to pollens, is commonly known as hay fever. Symptoms of allergic rhinitis include sneezing, bilateral nasal obstruction, clear nasal discharge, post-nasal drip, and nasal pruritus.
The management of allergic rhinitis involves allergen avoidance and medication. For mild-to-moderate intermittent or mild persistent symptoms, oral or intranasal antihistamines may be prescribed. For moderate-to-severe persistent symptoms or if initial drug treatment is ineffective, intranasal corticosteroids may be recommended. In some cases, a short course of oral corticosteroids may be necessary to cover important life events. Topical nasal decongestants, such as oxymetazoline, may also be used for short periods, but prolonged use can lead to tachyphylaxis and rebound hypertrophy of the nasal mucosa (rhinitis medicamentosa) upon withdrawal.
In summary, allergic rhinitis is a common condition that can cause discomfort and affect daily activities. Proper management involves identifying and avoiding allergens, as well as using medication as prescribed by a healthcare professional.

A 25-year-old male has been diagnosed with nasal polyps. Which medication sensitivity is commonly linked to this condition?
Your Answer: ACE inhibitors
Correct Answer: Aspirin
Explanation:Understanding Nasal Polyps
Nasal polyps are a relatively uncommon condition affecting around 1% of adults in the UK. They are more commonly seen in men and are not typically found in children or the elderly. There are several associations with nasal polyps, including asthma (particularly late-onset asthma), aspirin sensitivity, infective sinusitis, cystic fibrosis, Kartagener’s syndrome, and Churg-Strauss syndrome. When asthma, aspirin sensitivity, and nasal polyposis occur together, it is known as Samter’s triad.
The symptoms of nasal polyps include nasal obstruction, rhinorrhoea, sneezing, and a poor sense of taste and smell. It is important to note that any unusual symptoms, such as unilateral symptoms or bleeding, require further investigation. If nasal polyps are suspected, patients should be referred to an ear, nose, and throat (ENT) specialist for a full examination.
The management of nasal polyps typically involves the use of topical corticosteroids, which can shrink polyp size in around 80% of patients. Overall, understanding nasal polyps and their associations can help with early detection and appropriate management.

Question 4
Correct
-
A 53-year-old male smoker presents to the emergency department with a sore throat that has been bothering him for a day. He reports feeling generally unwell and has a hoarse voice, but no cough. He has been unable to swallow for the past three hours and is spitting out saliva. During examination, he has a temperature of 38ºC and trismus. There are no obvious abnormalities in his oropharynx, and his tonsils appear normal. Additionally, he has bilateral cervical lymphadenopathy.
What is the most appropriate course of action for managing this patient?Your Answer: Immediate ENT evaluation
Explanation:If a patient presents with acute sore throat but no visible signs in the oropharynx, and experiences severe symptoms such as difficulty swallowing, sepsis, or trismus, it is crucial to seek urgent evaluation from an ENT specialist. This is because these symptoms may indicate a deeper airway infection, such as supraglottitis, which can be life-threatening. Therefore, the patient should not be discharged without a thorough examination, including flexible nasendoscopy. If supraglottitis is diagnosed, treatment should involve IV antibiotics, IV dexamethasone, and adrenaline nebulizers. The patient should be closely monitored in an airway monitored bed, such as in an ENT ward or ICU if necessary.
Sore throat is a term used to describe various conditions such as pharyngitis, tonsillitis, and laryngitis. According to Clinical Knowledge Summaries, throat swabs and rapid antigen tests should not be routinely carried out for patients with a sore throat. Pain relief can be managed with paracetamol or ibuprofen, and antibiotics are not typically necessary. However, in cases where there is marked systemic upset, unilateral peritonsillitis, a history of rheumatic fever, an increased risk from acute infection, or when three or more Centor criteria are present, antibiotics may be indicated. The Centor and FeverPAIN scoring systems can be used to determine the likelihood of isolating Streptococci. If antibiotics are necessary, phenoxymethylpenicillin or clarithromycin (for penicillin-allergic patients) can be given for a 7 or 10 day course. It is worth noting that a single dose of oral corticosteroid may reduce the severity and duration of pain, although this has not yet been incorporated into UK guidelines.

A 42-year-old man visits his GP complaining of a headache and thick nasal discharge that has persisted for six days. He reports the headache as a frontal pressure pain that worsens when he bends forward. He denies experiencing cough or general malaise. His vital signs are heart rate 62/min, respiratory rate 13/min, blood pressure 127/63 mmHg, and temperature 36.2 ºC. He has a medical history of asthma, which he manages with his salbutamol inhaler. What is the appropriate management plan for the most likely diagnosis?
Your Answer: Intranasal corticosteroids
Correct Answer: Analgesia and abundant fluids
Explanation:For uncomplicated acute sinusitis, antibiotics are not necessary. Instead, the recommended treatment is pain relief and staying hydrated. The patient in this scenario has typical symptoms of acute sinusitis, such as facial pain, nasal discharge, and difficulty breathing. Antibiotics are only prescribed in severe cases or when the patient is at high risk of complications. Co-amoxiclav is an example of an antibiotic that may be used in these situations. Intranasal corticosteroids may be prescribed if the condition lasts longer than ten days. Intranasal decongestants and oral corticosteroids are not effective treatments for acute sinusitis and should not be used.
Acute sinusitis is a condition where the mucous membranes of the paranasal sinuses become inflamed. This inflammation is usually caused by infectious agents such as Streptococcus pneumoniae, Haemophilus influenzae, and rhinoviruses. Certain factors can predispose individuals to this condition, including nasal obstruction, recent local infections, swimming/diving, and smoking. Symptoms of acute sinusitis include facial pain, nasal discharge, and nasal obstruction. Treatment options include analgesia, intranasal decongestants or nasal saline, and intranasal corticosteroids. Oral antibiotics may be prescribed for severe presentations, but they are not typically required. In some cases, an initial viral sinusitis can worsen due to secondary bacterial infection, which is known as double-sickening.

A 44-year-old man visits his GP with complaints of vertigo. He had a cough and sore throat last week and has been experiencing a spinning sensation since then. The vertigo can last for hours and causes significant nausea, making it difficult for him to leave the house and go to work as a teacher. During an ENT examination, the GP observes horizontal nystagmus and intact tympanic membranes with no hearing loss. What is the best course of treatment?
Your Answer: Epley manoeuvre
Correct Answer: Short course of oral prochlorperazine
Explanation:In cases of vestibular neuronitis, prochlorperazine can be effective during the acute phase, but it should not be continued for an extended period as it can hinder the central compensatory mechanisms that aid in recovery. This patient’s symptoms, including recurrent vertigo attacks, nausea, and horizontal nystagmus, are consistent with vestibular neuronitis, likely triggered by a recent viral upper respiratory tract infection. A brief course of oral prochlorperazine is recommended, with the option of using buccal or intramuscular administration for more severe cases. However, it is important to discontinue prochlorperazine after a few days to avoid impeding the recovery process. Long-term use of prochlorperazine would not be appropriate in this situation.
Understanding Vestibular Neuronitis
Vestibular neuronitis is a type of vertigo that typically occurs after a viral infection. It is characterized by recurrent episodes of vertigo that can last for hours or days, accompanied by nausea and vomiting. Horizontal nystagmus, or involuntary eye movements, is a common symptom, but there is usually no hearing loss or tinnitus.
It is important to distinguish vestibular neuronitis from other conditions that can cause similar symptoms, such as viral labyrinthitis or posterior circulation stroke. The HiNTs exam can be used to differentiate between vestibular neuronitis and stroke.
Treatment for vestibular neuronitis may involve medications such as prochlorperazine or antihistamines to alleviate symptoms. However, vestibular rehabilitation exercises are often the preferred treatment for patients with chronic symptoms. These exercises can help to retrain the brain and improve balance and coordination. With proper management, most people with vestibular neuronitis can recover fully and resume their normal activities.

A 32-year-old man complains of left ear pain and hearing loss for the past week. He is an avid swimmer. During examination, you observe pre-auricular lymph nodes on the left side. The ear is inflamed, red, and tender to touch. A small amount of yellow discharge is visible in the ear canal.
What is the initial treatment of choice after obtaining swabs?Your Answer: No treatment needed as likely to self resolve
Correct Answer: Topical antibiotic drops
Explanation:Patients suffering from otitis media typically experience relief from symptoms within 4 days without the need for antibiotics. While antibiotics can help shorten the duration of symptoms, they come with the risk of side effects and drug resistance. Therefore, treatment is usually postponed unless symptoms persist, the patient is generally unwell, or symptoms affect both ears. In rare cases, ear syringing may be used as a secondary treatment to remove debris from the ear canal.
Understanding Otitis Externa: Causes, Features, and Management
Otitis externa is a common condition that often prompts patients to seek medical attention. It is characterized by ear pain, itch, and discharge, and is caused by various factors such as infection, seborrhoeic dermatitis, and contact dermatitis. Swimming is also a common trigger of otitis externa. Upon examination, the ear canal appears red, swollen, or eczematous.
The recommended initial management of otitis externa involves the use of topical antibiotics or a combination of topical antibiotics with a steroid. However, if the tympanic membrane is perforated, aminoglycosides are traditionally not used. In cases where there is canal debris, removal may be necessary, while an ear wick may be inserted if the canal is extensively swollen. Second-line options include oral antibiotics, taking a swab inside the ear canal, and empirical use of an antifungal agent.
It is important to note that if a patient fails to respond to topical antibiotics, referral to an ENT specialist may be necessary. Malignant otitis externa is a more serious condition that is more common in elderly diabetics. It involves the extension of infection into the bony ear canal and the soft tissues deep to the bony canal, and may require intravenous antibiotics.
Overall, understanding the causes, features, and management of otitis externa is crucial in providing appropriate care and preventing complications.

A 45-year-old woman presents to her General Practitioner after discovering a firm lump just under her tongue on the right side. She has been experiencing discomfort and mild swelling in the same area while eating for the past few days. She is stable and not running a fever.
What is the most suitable management option for this probable diagnosis?Your Answer: Watchful waiting
Correct Answer: Short course of NSAIDs and referral to an ENT surgeon
Explanation:Management of Salivary Gland Stones: Recommended Approaches and Guidelines
Salivary gland stones, or sialolithiasis, can cause pain and swelling of the affected gland, triggered by salivary flow stimulation during eating or chewing. If left untreated, these stones can lead to secondary infections, cellulitis, and airway compromise. Here are some recommended approaches and guidelines for managing salivary gland stones:
Referral to an ENT Surgeon and NSAIDs
If a salivary stone is suspected, a referral to an ENT surgeon should be made, with the urgency guided by clinical judgement. Patients should also be advised to remain well hydrated, and NSAIDs can be used to relieve any pain.Antibiotics and Referral to an ENT Surgeon
Antibiotics should only be used if there is a suspicion of a secondary infection, typically suggested by persistent pain and swelling, sometimes with fever and systemic upset. In this case, a referral to an ENT surgeon is also recommended.Oral Antibiotics and NSAIDs
NSAIDs can be used to relieve any pain, but antibiotics should only be used if there is a suspicion of a secondary infection. This is typically suggested by persistent pain and swelling, sometimes with fever and systemic upset.Oral Steroids
Oral steroids have no role in the management of salivary gland stones.Watchful Waiting
Left untreated, salivary gland stones can cause significant stress and psychological distress to patients. Therefore, it is not recommended to adopt a watchful waiting approach. -

A 58-year-old man complains of recurrent episodes of vertigo and dizziness. These episodes are usually triggered by a change in head position and usually last for about 30 seconds. The examination of the cranial nerves and ears shows no abnormalities. His blood pressure is 122/80 mmHg while sitting and 118/76 mmHg while standing. Assuming that the diagnosis is benign paroxysmal positional vertigo, what is the most suitable course of action to confirm the diagnosis?
Your Answer: Dix-Hallpike manoeuvre
Explanation:Understanding Benign Paroxysmal Positional Vertigo
Benign paroxysmal positional vertigo (BPPV) is a common condition that causes sudden dizziness and vertigo triggered by changes in head position. It typically affects individuals over the age of 55 and is less common in younger patients. Symptoms include vertigo triggered by movements such as rolling over in bed or looking upwards, and may be accompanied by nausea. Each episode usually lasts between 10-20 seconds and can be diagnosed through a positive Dix-Hallpike manoeuvre, which involves the patient experiencing vertigo and rotatory nystagmus.
Fortunately, BPPV has a good prognosis and often resolves on its own within a few weeks to months. Treatment options include the Epley manoeuvre, which is successful in around 80% of cases, and vestibular rehabilitation exercises such as the Brandt-Daroff exercises. While medication such as Betahistine may be prescribed, it tends to have limited value. However, it is important to note that around half of people with BPPV will experience a recurrence of symptoms 3-5 years after their initial diagnosis.
Overall, understanding BPPV and its symptoms can help individuals seek appropriate treatment and manage their condition effectively.

A 68-year-old male visits his primary care physician with a complaint of persistent left-sided ear pain for over a month. He reports no hearing loss or discharge and feels generally healthy. He has a history of hypertension and currently smokes 15 cigarettes a day. Otoscopy reveals no abnormalities in either ear. What is the best course of action to take?
Your Answer: Refer to ENT under 2-week wait
Explanation:If a person experiences unexplained ear pain on one side for more than 4 weeks and there are no visible abnormalities during an otoscopy, it is important to refer them for further investigation under the 2-week wait. This is particularly crucial for individuals who smoke, as they are at a higher risk for head and neck cancer. Using topical antibiotic/steroid drops or nasal steroid sprays without identifying any underlying pathology is not recommended. While amitriptyline may provide relief for symptoms, it should not be used as a substitute for proper diagnosis and treatment. Referring the patient for further evaluation is necessary to rule out the possibility of malignancy.
Understanding Head and Neck Cancer
Head and neck cancer is a broad term that encompasses various types of cancer, including oral cavity cancers, pharynx cancers, and larynx cancers. Symptoms of head and neck cancer may include a neck lump, hoarseness, persistent sore throat, and mouth ulcers.
To ensure prompt diagnosis and treatment, the National Institute for Health and Care Excellence (NICE) has established suspected cancer pathway referral criteria. For instance, individuals aged 45 and over with persistent unexplained hoarseness or an unexplained lump in the neck may be referred for an appointment within two weeks to assess for laryngeal cancer. Similarly, those with unexplained ulceration in the oral cavity lasting for more than three weeks or a persistent and unexplained lump in the neck may be referred for an appointment within two weeks to assess for oral cancer.
Dentists may also play a role in identifying potential cases of oral cancer. Individuals with a lump on the lip or in the oral cavity or a red or red and white patch in the oral cavity consistent with erythroplakia or erythroleukoplakia may be urgently referred for assessment within two weeks. Finally, individuals with an unexplained thyroid lump may be referred for an appointment within two weeks to assess for thyroid cancer. By following these guidelines, healthcare providers can help ensure timely diagnosis and treatment of head and neck cancer.

A 25-year-old woman presents to her General Practitioner with a complaint of difficulty sleeping due to a blocked nose at night. She uses inhalers regularly for wheezing during cold weather and experiences a cough at night. What is the most common complication of her underlying diagnosis that she may be experiencing?
Your Answer: Allergic fungal sinusitis
Correct Answer: Nasal Polyps
Explanation:Understanding Nasal Polyps and Associated Conditions
Nasal polyps are a common condition that can cause a blocked nose, interrupting sleep and wheezing upon exertion. They are often associated with asthma, which is found along the atopic spectrum of diseases. Other conditions commonly associated with nasal polyps include allergic rhinitis and sinusitis.
Allergic fungal sinusitis is another condition that can cause nasal polyps, but it is more commonly found in warmer climates and is not the most common cause in the United Kingdom. Paracetamol sensitivity is not associated with nasal polyps, but aspirin sensitivity is and can be part of Samter’s triad if the patient also has asthma.
Chronic obstructive pulmonary disease (COPD) is not associated with nasal polyps, and it would be rare to see in a young patient unless there was underlying alpha-1 anti-trypsin disease. COPD is most commonly seen in long-term smokers and presents with symptoms such as shortness of breath and a longstanding cough.
Diabetes mellitus is not associated with nasal polyps and would present with other symptoms such as polyuria, polydipsia, and fatigue. Understanding the conditions associated with nasal polyps can help with diagnosis and treatment.

A 28-year-old presents with profuse epistaxis (nose bleed) after being hit in the nose during a boxing match. The bleeding stops after applying direct pressure and packing the nose. Which vascular territory is most likely to have been impacted?
Your Answer: Kiesselbach’s plexus
Explanation:Understanding Epistaxis: Causes and Management
Epistaxis, or nosebleed, can occur from two areas: the anterior bleed from the Kiesselbach’s plexus and the posterior bleed from the sphenopalatine artery. The former is usually caused by trauma, involving the anterior and posterior ethmoid arteries, superior labial artery, and greater palatine artery. On the other hand, the latter is triggered by underlying pathologies such as hypertension or old age.
To manage epistaxis, direct pressure to the bleeding point, packing of the nose, or surgical ligation or selective embolization of the relevant artery may be necessary. It is important to note that significant episodes of epistaxis may lead to a considerable amount of blood loss, especially in the elderly, which can be masked by ingestion of the blood into the digestive tract. Thus, clotting and hemoglobin levels should always be checked.
It is worth noting that the nasal artery is not involved in epistaxis, as it is a terminal branch of the ophthalmic artery emerging from the orbit. Similarly, the superficial temporal artery and zygomatic artery have no involvement in epistaxis. The former is a major artery of the head arising from the internal carotid and passing anterior to the pinna, while the latter runs across the top of the zygomatic arch.
In summary, understanding the causes and management of epistaxis is crucial in preventing significant blood loss and ensuring proper treatment.

A 43-year-old male accountant visits the clinic with a persistent hoarseness that has been bothering him for the past 4 weeks. He reports that this is affecting his work performance. He denies experiencing any sore throat, difficulty swallowing, or cough. He has been smoking 20 cigarettes daily for the last 25 years and drinks a glass of beer every day. Apart from this, he is in good health. What is the best course of action for managing his condition?
Your Answer: 2-week rule referral to ENT specialist
Explanation:If a patient aged over 45 years old has persistent and unexplained hoarseness, it is recommended by NICE to urgently refer them to an ENT specialist under the 2-week wait rule. This is because they may have laryngeal cancer. While a chest radiograph is important, it is more appropriate to prioritize the referral to ENT if cancer is suspected. It is not appropriate to delay the referral or provide false reassurance. While advice on smoking cessation and alcohol should be given, specialist referral is the most important aspect of management in this situation.
Understanding Hoarseness and its Causes
Hoarseness is a condition that can be caused by various factors. One of the most common causes is voice overuse, which can strain the vocal cords and lead to hoarseness. Smoking is another factor that can contribute to hoarseness, as it can irritate the throat and vocal cords. Viral illnesses, hypothyroidism, and gastro-oesophageal reflux are also known to cause hoarseness. In some cases, hoarseness can be a symptom of laryngeal or lung cancer.
When investigating patients with hoarseness, it is important to consider a chest x-ray to rule out any apical lung lesions. If laryngeal cancer is suspected, referral guidelines recommend a suspected cancer pathway referral to an ENT specialist for individuals aged 45 and over with persistent unexplained hoarseness or an unexplained lump in the neck. By understanding the causes of hoarseness and seeking appropriate medical attention, individuals can receive the necessary treatment and improve their vocal health.

A 45-year-old businessman presents to the Emergency Department with his second episode of epistaxis in a 24 hour period. On each occasion, the nosebleeds stopped with pressure applied just below the nasal bridge, but the most recent bleed went on for 30 minutes. He has hypertension, for which he takes medication regularly. He also admits to smoking a pack of cigarettes per day and drinking 10-15 units of alcohol each week. There is no history of trauma. He is worried about the problem affecting his work, as he has an important meeting the following day.
On examination, he looks well and is not pale, and his blood pressure and pulse are within normal limits. He is peripherally well perfused. On inspection of the nasal vestibule, there are prominent blood vessels visible on the right side of the nasal septum, with a small amount of clotted blood also present.
What is the most appropriate management plan for this patient?Your Answer: Give advice on first aid measures and reassure her that the problem is normally self limiting
Correct Answer: Cauterise the bleeding point using silver nitrate
Explanation:Treatment Options for Epistaxis: From Simple First-Aid Measures to Invasive Procedures
Epistaxis, or nosebleed, is a common condition that can be treated through simple first-aid measures. However, in cases of repeated or prolonged nosebleeds, more invasive treatment may be necessary. Here are some treatment options for epistaxis:
Cauterization: If an anterior bleeding point is seen, cautery can be attempted. This is usually achieved by the application of a silver nitrate stick to the area for around 10 seconds after giving topical local anesthesia.
Blood tests and investigations: Blood tests and other investigations are of little use, as an underlying cause is highly unlikely in a young and otherwise well patient.
First-aid measures: Epistaxis is mainly treated through simple first-aid measures. It is important to reassure the patient that the problem is normally self-limiting.
Nasal tampon: Bleeds that do not settle with cautery, or significant bleeds where a bleeding point cannot be seen, require the application of a nasal tampon and referral to ENT.
Admission: This patient does not require admission. Blood tests are unlikely to be helpful, and she is haemodynamically stable.
In summary, treatment options for epistaxis range from simple first-aid measures to invasive procedures. The choice of treatment depends on the severity and frequency of the nosebleeds.

A 5-year-old girl presents with a sore throat that has been bothering her for 3 days. She has no cough or runny nose. Her mother has kept her home from preschool. Upon examination, she has a fever and swollen tonsils with white patches. She also has tender lymph nodes in her neck.
What is the most appropriate treatment for this patient? Choose ONE answer only.Your Answer: Phenoxymethylpenicillin for 10 days
Explanation:Antibiotic Treatment for Tonsillitis Based on Centor Score
Tonsillitis is a common condition that can be caused by a bacterial or viral infection. Antibiotics are not always necessary for a sore throat, but in cases where the patient has a high probability of a bacterial infection-induced sore throat, antibiotic therapy may be beneficial. The Centor score is a tool used to predict bacterial infection in people with a sore throat. A score of 3 or 4 means that the patient has a high probability of having a bacterial infection-induced sore throat and may benefit from antibiotics.
The first-line antibiotic therapy for tonsillitis is 10 days of phenoxymethylpenicillin. However, it is important to check the patient’s allergy status before prescribing penicillin. If the patient is allergic to penicillin, 5 days of erythromycin or clarithromycin can be used. Amoxicillin and other broad-spectrum antibiotics should be avoided in the blind treatment of throat infections.
In cases where the Centor score is 2, a bacterial infection is less likely, and antibiotic therapy is unlikely to be required. In such cases, conservative management such as mouth rinses can be used to alleviate discomfort and swelling.
It is important to note that antibiotic therapy should only be prescribed when necessary, and a delayed prescription may be considered in some cases. A delayed prescription should only be considered if it is safe not to treat immediately.

A 79-year-old man presents to the emergency department with persistent left-sided epistaxis following a fall and hitting his nose on a door. He has a medical history of hypertension managed with amlodipine, atrial fibrillation managed with apixaban, stroke, and type 2 diabetes managed with metformin. On examination, he has active bleeding from the left anterior nasal septum and is spitting blood. Despite attempting to control the bleeding by squeezing his nose for 30 minutes and inserting a Rapid Rhino, the bleeding persists. What is an indication for surgical intervention in this case?
Your Answer: Failure of nasal packing
Explanation:If all emergency measures fail to stop epistaxis, sphenopalatine ligation in a surgical setting may be necessary.
To manage epistaxis in an emergency, it is important to provide adequate first aid for at least 20 minutes by firmly squeezing both nasal ala and sitting forward. Ice in the mouth can also be helpful. Topical adrenaline and local anaesthetic, as well as topical tranexamic acid, can be applied. If these measures are unsuccessful, nasal packing with devices such as Rapid Rhino may be necessary. If the bleeding persists, a posterior pack or Foley catheter may be used. In cases where all of these measures fail, surgical intervention such as sphenopalatine artery ligation may be required.
Understanding Epistaxis: Causes and Management
Epistaxis, commonly known as nosebleeds, can be categorized into anterior and posterior bleeds. Anterior bleeds usually have a visible source of bleeding and occur due to an injury to the network of capillaries that form Kiesselbach’s plexus. On the other hand, posterior haemorrhages tend to be more severe and originate from deeper structures. They are more common in older patients and pose a higher risk of aspiration and airway obstruction.
Most cases of epistaxis are benign and self-limiting. However, certain factors can exacerbate the condition, such as nose picking, nose blowing, trauma to the nose, insertion of foreign bodies, bleeding disorders, and immune thrombocytopenia. Other causes include the use of cocaine, hereditary haemorrhagic telangiectasia, and granulomatosis with polyangiitis.
If the patient is haemodynamically stable, bleeding can be controlled with first aid measures. This involves asking the patient to sit with their torso forward and their mouth open, pinching the cartilaginous area of the nose firmly for at least 20 minutes, and using a topical antiseptic to reduce crusting and the risk of vestibulitis. If bleeding persists, cautery or packing may be necessary. Patients should be advised to avoid activities that increase the risk of re-bleeding.
In cases where emergency management fails, sphenopalatine ligation in theatre may be required. Patients with unknown or posterior sources of bleeding should be admitted to the hospital for observation and review. Overall, understanding the causes and management of epistaxis is crucial in providing effective care for patients experiencing this condition.

A 32-year-old man visits his GP complaining of a sore throat, runny nose, cough, feeling feverish and generally unwell for the past week. He reports no difficulty eating or drinking.
Upon examination, his temperature is 37.2°C, and his chest is clear, but he has a dry cough. His tonsils are inflamed, but there is no exudate. He has no significant medical history.
Based on his Fever PAIN score, what would be the most appropriate course of action?Your Answer: Admit to hospital
Correct Answer: Advise her that antibiotics are not indicated at this point and to return in one week if there is no improvement
Explanation:Using the FeverPAIN Score to Determine Antibiotic Use for Pharyngitis
When a patient presents with symptoms of pharyngitis, it can be difficult to determine whether antibiotics are necessary. The FeverPAIN Score for Streptococcus pharyngitis was developed to help assess which patients have streptococcal pharyngitis and therefore require antibiotics.
The score assigns points based on the presence of fever, pus, quick attenuation of symptoms, inflamed tonsils, and cough.
Fever PAIN score
Fever – 1
Pus – 1
Attenuates quickly – 1
Inflamed tonsils – 1
No cough – 1
A score of 0-1 is associated with a low likelihood of streptococcal infection and does not require antibiotics. A score of 2-3 may warrant a delayed antibiotic prescription, while a score of 4 or more may require immediate antibiotics.In the case of a patient with a low FeverPAIN score, it is important to advise against antibiotics and instead recommend a follow-up visit in one week if there is no improvement. Safety netting should also be provided to ensure the patient is aware of potential warning signs of deterioration. By using the FeverPAIN score, healthcare providers can reduce inappropriate antibiotic use in pharyngitis and promote more effective treatment.

Which medication is most effective in preventing Meniere's disease attacks?
Your Answer: Betahistine
Explanation:Understanding Meniere’s Disease
Meniere’s disease is a condition that affects the inner ear and its cause is still unknown. It is more commonly seen in middle-aged adults but can occur at any age and affects both men and women equally. The condition is characterized by excessive pressure and progressive dilation of the endolymphatic system. The most prominent symptoms of Meniere’s disease are recurrent episodes of vertigo, tinnitus, and sensorineural hearing loss. Other symptoms include a sensation of aural fullness or pressure, nystagmus, and a positive Romberg test. These episodes can last from minutes to hours and are typically unilateral, but bilateral symptoms may develop over time.
The natural history of Meniere’s disease shows that symptoms usually resolve in the majority of patients after 5-10 years. However, most patients are left with some degree of hearing loss, and psychological distress is common. To manage the condition, an ENT assessment is required to confirm the diagnosis. Patients should inform the DVLA, and the current advice is to cease driving until satisfactory control of symptoms is achieved. During acute attacks, buccal or intramuscular prochlorperazine may be administered, and admission to the hospital may be required. To prevent future attacks, betahistine and vestibular rehabilitation exercises may be of benefit.
In summary, Meniere’s disease is a condition that affects the inner ear and can cause recurrent episodes of vertigo, tinnitus, and hearing loss. While the cause is unknown, there are management strategies available to help control symptoms and prevent future attacks. It is important for patients to seek medical attention and inform the DVLA to ensure their safety and well-being.

Question 19
Correct

A 43-year-old male patient presents with a chief complaint of hearing difficulty. During the examination, you perform Weber's test and find that he hears the sound most loudly in his right ear. On conducting Rinne test, the sound is loudest when the tuning fork is placed in front of the ear canal on the left and loudest when placed on the mastoid process on the right. What type of hearing loss is evident in this case?
Your Answer: Conductive hearing loss on the right
Explanation:The presence of conductive hearing loss can be identified by conducting Rinne and Weber tests. During the Rinne test, bone conduction will be more audible than air conduction, while the Weber test will indicate the affected ear.
If the hearing loss is conductive and affects the right ear, bone conduction will be louder than air conduction. This is because the ear canal, middle ear, or tympanic membrane is unable to conduct sound waves effectively. The Weber test will also indicate that the affected ear is where the sound is loudest.
The other options provided are incorrect as they do not align with the results of the examination. In sensorineural hearing loss, air conduction is louder than bone conduction.
Conductive hearing loss can be caused by various factors, including impacted earwax, inner ear effusion, debris or foreign objects in the ear canal, a perforated eardrum, or otosclerosis.
Rinne’s and Weber’s Test for Differentiating Conductive and Sensorineural Deafness
Rinne’s and Weber’s tests are two diagnostic tools used to differentiate between conductive and sensorineural deafness. Rinne’s test involves placing a tuning fork over the mastoid process until the sound is no longer heard, then repositioning it just over the external acoustic meatus. A positive test indicates that air conduction (AC) is better than bone conduction (BC), while a negative test suggests conductive deafness if BC is greater than AC.
On the other hand, Weber’s test involves placing a tuning fork in the middle of the forehead equidistant from the patient’s ears and asking which side is loudest. In unilateral sensorineural deafness, sound is localized to the unaffected side, while in unilateral conductive deafness, sound is localized to the affected side.
To interpret the results of Rinne’s and Weber’s tests, a normal result indicates that AC is greater than BC bilaterally, and the sound is midline in Weber’s test. Conductive hearing loss is indicated by BC being greater than AC in the affected ear, while AC is greater than BC in the unaffected ear, and the sound lateralizes to the affected ear in Weber’s test. Sensorineural hearing loss is indicated by AC being greater than BC bilaterally, and the sound lateralizes to the unaffected ear in Weber’s test.

A 42-year-old woman presents to her General Practitioner with a 4-month history of nasal congestion and coughing. Over the previous few days, she has also been experiencing a persistent headache which seems to be worse when she leans forward.
Which of the following is the most probable diagnosis?
Your Answer:
Correct Answer: Chronic rhinosinusitis
Explanation:Differentiating Chronic Rhinosinusitis from Other Headache Disorders
Chronic rhinosinusitis is a condition characterized by inflammation of the paranasal sinuses and nasal passages that lasts for 12 weeks or longer. Patients with chronic rhinosinusitis typically present with symptoms such as nasal congestion, coughing, persistent headache that worsens on bending forwards, facial pain, nasal discharge, and postnasal drip. Predisposing factors for chronic rhinosinusitis include atopy, nasal obstruction, recent local infection, swimming or diving, and smoking. Management of chronic rhinosinusitis involves avoidance of allergens, intranasal corticosteroids, and nasal irrigation with saline.
Acute sinusitis shares many features with chronic rhinosinusitis, but the history of symptoms is much shorter. Treatment for acute sinusitis includes analgesia, intranasal decongestants or nasal saline, and intranasal corticosteroids if symptoms persist for more than ten days. Oral antibiotics may be given for severe presentations.
Cluster headaches are characterized by intense, sharp, stabbing pain around one eye, accompanied by eye redness, lacrimation, lid swelling, nasal stuffiness, skin erythema, miosis or ptosis. Cluster headaches occur in clusters lasting between four and 12 weeks, with patients feeling completely fine in between clusters. Tension headaches are described as a band-like headache that does not impair activities of daily living.
Postnasal drip (PND) typically presents with a chronic cough and bad breath, unlike the presentation in chronic rhinosinusitis. It is important to differentiate chronic rhinosinusitis from other headache disorders to ensure appropriate management and treatment.

A 10-year-old girl presents to the general practice clinic with a sore throat and fever that have been present for 3 days. What clinical sign would indicate that the patient may have a bacterial throat infection and could benefit from antibiotics? Choose ONE positive indicator from the options provided.
Your Answer:
Correct Answer: Tender cervical lymphadenopathy
Explanation:Assessing the Need for Antibiotics in Acute Sore Throat: Understanding the Centor Criteria and Other Indicators
When a patient presents with a sore throat, it is important to determine whether antibiotics are necessary for treatment. The Centor criteria and FeverPAIN score are two approved scoring systems used to predict the likelihood of a bacterial cause for the sore throat.
Tender cervical lymphadenopathy is one of the parameters in the Centor criteria and scores 1 point. Other parameters include age, exudate on tonsils, absence of cough, and fever. A score of 3 or more suggests a high probability of bacterial infection and the need for antibiotic treatment.
Cough present is not an indicator for antibiotic therapy, but its absence is one of the factors in the Centor criteria. Sore throat alone is also not an indicator for antibiotics, but a score of 4-5 on the FeverPAIN score or a Centor criteria score above 3 may indicate the need for antibiotics.
Vomiting and nasal congestion are not included in either scoring system for determining the need for antibiotics. However, vomiting may be a sign of severe illness and dehydration, and any patient presenting with vomiting and a sore throat should be assessed for signs of sepsis and dehydration. Nasal congestion may suggest a viral cause for the sore throat, but alternative causes should still be assessed.
In summary, understanding the Centor criteria and other indicators can help healthcare providers determine whether antibiotics are necessary for treating acute sore throat.

During a standard cranial nerve assessment, the subsequent results are noted: Rinne's test: Air conduction > bone conduction in both ears Weber's test: Localises to the right side What is the significance of these test outcomes?
Your Answer:
Correct Answer: Left sensorineural deafness
Explanation:If there is a sensorineural issue during Weber’s test, the sound will be perceived on the healthy side (right), suggesting a problem on the opposite side (left).

A 45-year-old woman attends the general practice surgery with her husband who is concerned that since she has started working from home several months ago, she has had a continuous cold. She reports frequent sneezing, clear nasal discharge and a terrible taste in her mouth in the morning. Her eyes look red and feel itchy. She has noticed that the symptoms improve when she is at the office or when they have been on vacation. She has a history of migraines and is otherwise well. She has not yet tried any treatment for her symptoms.
Which of the following is the most likely diagnosis?Your Answer:
Correct Answer: Allergic rhinitis
Explanation:Understanding Allergic Rhinitis: Symptoms, Causes, and Differential Diagnosis
Allergic rhinitis is a common condition that presents with a range of symptoms, including sneezing, itchiness, rhinorrhea, and a blocked nose. Patients with allergic rhinitis often experience eye symptoms such as bilateral itchiness, redness, and swelling. While the diagnosis of allergic rhinitis is usually based on characteristic features, it is important to exclude infectious and irritant causes.
In this case, the patient’s symptoms and medical history suggest an allergic cause for his condition. It would be prudent to inquire about his new home environment, as the allergen may be animal dander from a pet or house dust mites if there are more soft furnishings and carpets than in his previous home.
Other possible diagnoses, such as acute infective rhinitis, acute sinusitis, rhinitis medicamentosa, and nasopharyngeal carcinoma, can be ruled out based on the patient’s symptoms and medical history. For example, acute infective rhinitis would present more acutely with discolored nasal discharge and other upper respiratory tract infection symptoms. Acute sinusitis would present with facial pain or pressure and discolored nasal discharge. Rhinitis medicamentosa is caused by long-term use of intranasal decongestants, which is not the case for this patient. Nasopharyngeal carcinoma is rare and typically presents with unilateral symptoms and a middle-ear effusion.
Overall, understanding the symptoms, causes, and differential diagnosis of allergic rhinitis is crucial for proper management and treatment of this common condition.

A 75-year-old man visits his doctor with worries about a tiny spot on his inner, lower lip. The spot has been there for about a month and has not shown any changes during this time. He reports no pain. He used to smoke but quit a decade ago. During the examination, his oral hygiene appears to be good, and there is a small, white patch less than 1 cm in size on the inner surface of his lower lip.
What is the best course of action for this patient?Your Answer:
Correct Answer: Refer oral surgery under 2-week wait
Explanation:If a patient has had persistent oral ulceration for more than three weeks, it is recommended that they be referred to oral surgery under the two week wait. This is especially important for smokers, as it raises suspicion for malignancy. Referring the patient to oral surgery under the two week wait is more appropriate than routine referral, as it allows for a quicker diagnosis. Following up with a community dentist is not recommended, as it may cause delays in diagnosis if the patient does not attend. While chlorhexidine may provide symptom relief, it does not address the underlying diagnosis, and reassurance alone is also not sufficient. Medical practitioners should refer patients with this presentation to oral surgery.
When to Refer Patients with Mouth Lesions for Oral Surgery
Mouth lesions can be a cause for concern, especially if they persist for an extended period of time. In cases where there is unexplained oral ulceration or mass that lasts for more than three weeks, or red and white patches that are painful, swollen, or bleeding, a referral to oral surgery should be made within two weeks. Additionally, if a patient experiences one-sided pain in the head and neck area for more than four weeks, which is associated with earache but does not result in any abnormal findings on otoscopy, or has an unexplained recent neck lump or a previously undiagnosed lump that has changed over a period of three to six weeks, a referral should be made.
Patients who have persistent sore or painful throats or signs and symptoms in the oral cavity that last for more than six weeks and cannot be definitively diagnosed as a benign lesion should also be referred. It is important to note that the level of suspicion should be higher in patients who are over 40, smokers, heavy drinkers, and those who chew tobacco or betel nut (areca nut). By following these guidelines, healthcare professionals can ensure that patients with mouth lesions receive timely and appropriate care.

A 7-year-old girl comes to the emergency department with a 2-day history of right-sided otalgia and otorrhoea. Her mother suspects a middle ear infection as she has had them before. During the examination, she is found to be running a fever and has tenderness behind her right ear. The affected ear appears more prominent than the other, and otoscopy reveals a red tympanic membrane with a visible tear and pus discharge. What is the typical initial treatment for this probable diagnosis?
Your Answer:
Correct Answer: IV antibiotics
Explanation:Mastoiditis is usually diagnosed based on clinical symptoms and requires immediate administration of IV antibiotics.
Upon examination, the patient displays symptoms consistent with mastoiditis, an infection of the mastoid air cells located in the temporal bone. This condition often arises as a complication of untreated or recurrent otitis media, as is the case here. Mastoiditis is the probable diagnosis due to tenderness upon palpation of the mastoid bone, swelling of the affected ear, and accompanying symptoms of otitis media.
The correct answer is IV antibiotics. Mastoiditis is typically diagnosed based on clinical presentation and requires urgent treatment with IV antibiotics.
Oral antibiotics are not the correct answer. Although antibiotics are necessary to treat mastoiditis, this condition is considered an emergency and therefore requires IV antibiotics as the preferred treatment method.
Routine referral to an ENT specialist is not the correct answer. Mastoiditis requires immediate treatment, and therefore a routine referral is not appropriate. The patient needs prompt access to IV antibiotics.
Topical antibiotics are not the correct answer. This treatment is not suitable for mastoiditis and is typically used to treat otitis externa.
Understanding Mastoiditis
Mastoiditis is a condition that occurs when an infection spreads from the middle ear to the mastoid air spaces of the temporal bone. It is characterized by severe pain behind the ear, fever, and a history of recurrent otitis media. Patients with mastoiditis are typically very unwell and may experience swelling, erythema, and tenderness over the mastoid process. In some cases, the external ear may protrude forwards and ear discharge may be present if the eardrum has perforated.
Diagnosis of mastoiditis is typically made based on clinical presentation, although a CT scan may be ordered if complications are suspected. Treatment involves the use of IV antibiotics to combat the infection. If left untreated, mastoiditis can lead to complications such as facial nerve palsy, hearing loss, and even meningitis.

A 62-year-old woman visits the clinic complaining of unpleasant breath and gurgling sounds while swallowing. She reports no other symptoms or changes in her health.
What is the MOST probable diagnosis?Your Answer:
Correct Answer: Pharyngeal pouch
Explanation:Pharyngeal Pouch and Hiatus Hernia: Two Common Causes of Oesophageal Symptoms
Pharyngeal pouch and hiatus hernia are two common conditions that can cause symptoms related to the oesophagus. A pharyngeal pouch is a diverticulum that forms in the posterior aspect of the oesophagus due to herniation between two muscles that constrict the inferior part of the pharynx. This pouch can trap food and cause halitosis, regurgitation of food or gurgling noises, and sometimes a palpable lump on the side of the neck. Treatment involves surgery to correct the herniation or sometimes to close the diverticulum.
Hiatus hernia, on the other hand, occurs when part of the stomach protrudes through the diaphragm into the chest cavity, leading to a retrosternal burning sensation, gastro-oesophageal reflux, and dysphagia. This condition is more common in older people and those with obesity or a history of smoking. Treatment may involve lifestyle changes, such as weight loss and avoiding trigger foods, as well as medications to reduce acid production or strengthen the lower oesophageal sphincter.
Other possible causes of oesophageal symptoms include gastro-oesophageal reflux disease (GORD), oesophageal candidiasis, and oesophageal carcinoma. GORD is a chronic condition that involves reflux of gastric contents into the oesophagus, causing symptoms of heartburn and acid regurgitation. Oesophageal candidiasis is a fungal infection that usually affects people with weakened immune systems. Oesophageal carcinoma is a type of cancer that can develop in the lining of the oesophagus, often with symptoms such as weight loss, dysphagia, abdominal pain, and dyspepsia. However, based on the history provided, pharyngeal pouch and hiatus hernia are more likely causes of the patient’s symptoms.

A 60-year-old man presents following a fall. During an assessment of his fall, he complained of balance problems, nausea and dizziness whenever he looked upwards, eg to change a light bulb. He denies loss of consciousness and did not injure himself during the fall. His past medical history consists of hypertension and high cholesterol.
On examination, his gait and balance and neurological examination are normal, and there are no injuries. The Hallpike test is positive.
Which of the following is the most appropriate management for this patient’s vertigo?Your Answer:
Correct Answer: Epley manoeuvre
Explanation:Management Options for Benign Paroxysmal Positional Vertigo (BPPV)
Benign paroxysmal positional vertigo (BPPV) is a common vestibular disorder that can cause dizziness and vertigo. The Epley manoeuvre is the best first-line management option for BPPV, as it can reposition the debris in the vestibular canals and provide rapid relief. If symptoms persist, investigations may be necessary to rule out more serious brain pathologies, but a brain MRI is not typically required for a BPPV diagnosis.
Medications such as betahistine or prochlorperazine may provide short-term relief of symptoms, but they do not address the underlying cause of BPPV. Vestibular retraining exercises, such as Brandt-Daroff exercises, can also be effective in reducing symptoms if they persist despite the Epley manoeuvre. Overall, a combination of these management options can help alleviate the symptoms of BPPV and improve quality of life for patients.

A 47-year-old man visits the GP clinic complaining of sudden vertigo, nausea, and vomiting that started this morning. He also mentions experiencing reduced hearing in his left ear. He has been recovering from a cold for the past week and has no other symptoms. During the examination, otoscopy shows no abnormalities. However, there is a spontaneous, uni-directional, and horizontal nystagmus. The head impulse test is impaired, and Rinne's and Weber's tests reveal a sensorineural hearing loss on the left side.
What is the most probable diagnosis?Your Answer:
Correct Answer: Viral labyrinthitis
Explanation:Acute viral labyrinthitis presents with sudden horizontal nystagmus, hearing issues, nausea, vomiting, and vertigo. It is typically preceded by a viral infection and can cause hearing loss. Unlike BPPV, it is not associated with hearing loss. A central cause such as a stroke is less likely as the nystagmus is unidirectional and the head impulse test is impaired. Vestibular neuritis has similar symptoms to viral labyrinthitis but does not result in hearing loss.
Labyrinthitis is a condition that involves inflammation of the membranous labyrinth, which affects both the vestibular and cochlear end organs. This disorder can be caused by a viral, bacterial, or systemic disease, with viral labyrinthitis being the most common form. It is important to distinguish labyrinthitis from vestibular neuritis, as the latter only affects the vestibular nerve and does not result in hearing impairment. Labyrinthitis, on the other hand, affects both the vestibular nerve and the labyrinth, leading to vertigo and hearing loss.
The typical age range for presentation of labyrinthitis is between 40-70 years old. Patients usually experience an acute onset of symptoms, including vertigo that is not triggered by movement but worsened by it, nausea and vomiting, hearing loss (which can be unilateral or bilateral), tinnitus, and preceding or concurrent upper respiratory tract infection symptoms. Signs of labyrinthitis include spontaneous unidirectional horizontal nystagmus towards the unaffected side, sensorineural hearing loss, an abnormal head impulse test, and gait disturbance that may cause the patient to fall towards the affected side.
Diagnosis of labyrinthitis is primarily based on the patient’s history and physical examination. While episodes of labyrinthitis are typically self-limiting, medications such as prochlorperazine or antihistamines may help reduce the sensation of dizziness. Overall, it is important to accurately diagnose and manage labyrinthitis to prevent complications and improve the patient’s quality of life.

A 65-year-old man is brought to his General Practitioner by his daughter, who has noticed that his hearing on the right side has been progressively diminishing for the past six months. Additionally, he also complains of feeling unbalanced and of not being able to walk properly and leaning more towards the right side. On referral to the Ear, Nose and Throat (ENT) Department, the Consultant conducts a detailed clinical examination and finds nystagmus and dysdiadochokinesia, in addition to a sensorineural loss in his right ear.
Which of the following is the most appropriate diagnostic investigation for this patient?Your Answer:
Correct Answer: Magnetic resonance imaging (MRI)
Explanation:Diagnostic Tests for Acoustic Neuroma
Acoustic neuroma is a condition characterized by unilateral hearing loss and unsteady gait. The following diagnostic tests can aid in the diagnosis of this condition:
Magnetic Resonance Imaging (MRI): This is the preferred test for detecting acoustic neuroma as it can detect tumors as small as 1-1.3 mm. MRI with gadolinium contrast is recommended in cases where brainstem testing is abnormal or there is a high suspicion of vestibular schwannoma.
Plain Computerized Tomography (CT) Scan: CT scan with contrast can provide prognostic information on post-operative hearing loss by assessing the widening of the internal auditory canal and the extent of tumor growth. However, plain CT cannot detect some cases of acoustic neuroma.
Otoscopy: This test is useful in diagnosing conditions of bone conduction deafness but is of limited or no value in cases of sensorineural deafness.
Pure Tone Audiometry (PTA): This is the best initial screening laboratory test for the diagnosis of acoustic neuroma. Test results typically show an asymmetric sensorineural hearing loss, usually more prominent at higher frequencies.
Vestibular Colorimetric Test: This test has limited utility as a screening test for the diagnosis of acoustic neuroma. A decreased or absent caloric response on the affected side may be seen, but with small-sized tumors, a normal response is often seen.
In conclusion, a combination of these diagnostic tests can aid in the accurate diagnosis of acoustic neuroma.

An 80-year-old woman visits her doctor with a complaint of progressive hearing loss in both ears. What is the MOST probable diagnosis?
Your Answer:
Correct Answer: Presbycusis
Explanation:Common Causes of Hearing Loss: A Brief Overview
Hearing loss can be caused by a variety of factors, including age, infection, genetic predisposition, and growths in the ear. Here are some common causes of hearing loss:
Presbyacusis: This is an age-related hearing loss that affects sounds at high frequency. It is the most likely diagnosis in cases of hearing loss in older adults.
Otitis externa: This is inflammation of the external ear canal, which can cause pain, discharge, and conductive deafness.
Cholesteatoma: This is a destructive and expanding growth consisting of keratinising squamous epithelium in the middle ear and/or mastoid process. It can cause ear discharge, conductive deafness, and other symptoms.
Ménière’s disease: This is a condition that causes sudden attacks of tinnitus, vertigo, a sensation of fullness in the ear, and fluctuating sensorineural hearing loss.
Otosclerosis: This is a form of conductive hearing loss that often occurs in early adult life. It can also cause tinnitus and transient vertigo.
If you are experiencing hearing loss, it is important to see a healthcare professional for an accurate diagnosis and appropriate treatment.
