Vertigo is most commonly caused by BPPV.

Benign paroxysmal positional vertigo (BPPV) is a common cause of vertigo that occurs suddenly when there is a change in head position. It is more prevalent in individuals over the age of 55 and is less common in younger patients. Symptoms of BPPV include dizziness and vertigo, which can be accompanied by nausea. Each episode typically lasts for 10-20 seconds and can be triggered by rolling over in bed or looking upwards. A positive Dix-Hallpike manoeuvre, which is indicated by vertigo and rotatory nystagmus, can confirm the diagnosis of BPPV.

Fortunately, BPPV has a good prognosis and usually 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 effectiveness. However, it is important to note that around half of individuals with BPPV may experience a recurrence of symptoms 3-5 years after their initial diagnosis.

The man’s symptoms suggest bacterial sinusitis, as he has experienced a double sickening where his symptoms initially improved but then suddenly worsened. This is often caused by a secondary bacterial infection following a viral rhinosinusitis. The presence of a fever and purulent discharge seen on rhinoscopy further support this diagnosis.

Trigeminal neuralgia would not cause a fever, while sialadenitis would result in swelling of only one salivary gland. Cavernous sinus thrombosis is a rare complication of bacterial sinusitis and is not likely in this case.

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 influenza, 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 necessary 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.

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 is also a common symptom, but there is no hearing loss or tinnitus.

It is important to differentiate vestibular neuronitis from other conditions such as viral labyrinthitis and posterior circulation stroke. The HiNTs exam can be used to distinguish between these conditions.

Treatment for vestibular neuronitis typically involves medication to alleviate symptoms, such as buccal or intramuscular prochlorperazine for severe cases, or a short course of oral medication for less severe cases. Vestibular rehabilitation exercises are also recommended for patients who experience chronic symptoms.

Understanding the symptoms and treatment options for vestibular neuronitis can help individuals manage this condition and improve their quality of life.

Understanding Otitis Externa: Causes, Features, and Management

Otitis externa is a prevalent condition that often prompts primary care visits in the UK. It is characterized by ear pain, itch, and discharge, and can be caused by bacterial or fungal infections, seborrhoeic dermatitis, or contact dermatitis. Swimming is also a common trigger for otitis externa. Upon examination, the ear canal may appear red, swollen, or eczematous.

The recommended initial management for otitis externa is 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. If there is canal debris, removal may be necessary, and if the canal is extensively swollen, an ear wick may be inserted. Second-line options include taking a swab inside the ear canal, considering contact dermatitis secondary to neomycin, or using oral antibiotics such as flucloxacillin if the infection is spreading. Empirical use of an antifungal agent may also be considered.

It is important to note that if a patient fails to respond to topical antibiotics, they should be referred to an ENT specialist. Malignant otitis externa is a more severe form of the 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. While some ENT doctors disagree, concerns about ototoxicity may arise with the use of aminoglycosides in patients with perforated tympanic membranes.

Immediate investigation is necessary for any oral cavity lesion that appears suspicious for erythroplakia or leukoplakia due to the risk of malignancy.

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 doesn’t 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.

Understanding Gingivitis and its Management

Gingivitis is a dental condition that is commonly caused by poor oral hygiene. It is characterized by red and swollen gums that bleed easily. In severe cases, it can lead to acute necrotizing ulcerative gingivitis, which is accompanied by painful bleeding gums, bad breath, and ulcers on the gums.

For patients with simple gingivitis, regular dental check-ups are recommended, and antibiotics are usually not necessary. However, for those with acute necrotizing ulcerative gingivitis, it is important to seek immediate dental attention. In the meantime, oral metronidazole or amoxicillin may be prescribed for three days, along with chlorhexidine or hydrogen peroxide mouthwash and simple pain relief medication.

It is crucial to maintain good oral hygiene to prevent gingivitis from developing or worsening. This includes brushing teeth twice a day, flossing daily, and using mouthwash regularly. By understanding the causes and management of gingivitis, individuals can take steps to protect their oral health and prevent complications.

If using olive oil drops to remove impacted earwax is unsuccessful, an alternative option is to use sodium bicarbonate drops to soften the wax.

It is important to note that Otomize ear spray contains neomycin, an antibiotic that can be harmful to patients with a perforated eardrum. Therefore, caution should be exercised when using these drops.

While ear syringing is a possibility, it is recommended to soften the wax with drops for at least two weeks prior to attempting the procedure.

Since the patient’s hearing is affected by the wax, a wait-and-see approach is not advisable. Referral to audiology is also unnecessary as the cause of the hearing loss is already known, and delaying treatment may worsen the condition.

Understanding earwax and Its Impacts

earwax is a natural substance produced by the body to protect the ear canal. However, it is not uncommon for earwax to become impacted, leading to a range of symptoms such as pain, hearing loss, tinnitus, and vertigo. In such cases, treatment is necessary to alleviate the discomfort caused by the impacted earwax. Primary care options for treatment include ear drops or irrigation, also known as ‘ear syringing’. It is important to note that treatment should not be administered if there is a suspected perforation or if the patient has grommets. Ear drops such as olive oil, sodium bicarbonate 5%, and almond oil can be used to help alleviate the symptoms of impacted earwax.

Prolonged use of intranasal decongestants like oxymetazoline should be avoided due to the development of tachyphylaxis, where increasing doses are needed to achieve the same effect. Additionally, stopping the medication can lead to rebound symptoms known as rhinitis medicamentosa. Therefore, it is best to encourage patients to discontinue the decongestant rather than prescribing a higher dose. Oral decongestants like pseudoephedrine are not commonly prescribed due to limited evidence supporting their effectiveness. For patients with allergic rhinitis, short-term use of oral corticosteroids may be recommended for severe symptoms, but intranasal corticosteroids and antihistamines are more practical options. Patients should also be advised on self-help strategies like allergen avoidance. Referral to an ENT specialist is not necessary for most cases of allergic rhinitis, except for those with red flags, suspected structural abnormalities, diagnostic uncertainty, or persisting symptoms despite optimal primary care management.

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 life. Understanding the different types of allergic rhinitis and its symptoms can help in managing the condition effectively. It is important to consult a healthcare professional for proper diagnosis and treatment.

For individuals with moderate-to-severe or persistent symptoms of allergic rhinitis, intranasal steroids are the recommended first-line treatment. They have been found to be more effective than oral antihistamines. Combining intranasal steroids with oral antihistamines can provide even better results.

If a person experiences persistent watery rhinorrhea despite using both intranasal steroids and oral antihistamines, an intranasal anticholinergic like ipratropium bromide can be added to the treatment plan.

In cases where symptoms are severe and significantly impacting quality of life despite optimal treatment, a short course of oral steroids may be considered. However, this should only be used for important life events.

If symptoms remain uncontrolled despite optimal management, immunotherapy may be considered as a future option.

Myths and Facts about Nasal Fractures

Nasal fractures are a common injury that can result from trauma to the face. However, there are several myths and misconceptions surrounding the diagnosis and management of these fractures. Here are some important facts to keep in mind:

Timing of Fracture Reduction

Myth: Fracture reduction can be performed immediately after injury.
Fact: Fracture reduction is best performed 5-7 days after injury, when swelling has subsided. Immediate reduction may be possible if there is little swelling.

Role of Radiological Imaging

Myth: Radiological imaging is essential in confirming the diagnosis of nasal fractures.
Fact: The diagnosis of nasal fracture is usually made clinically, and imaging is usually unnecessary. X-rays are unreliable in the diagnosis of nasal fractures and do not usually affect patient management.

Significance of Clear Rhinorrhoea

Myth: Clear rhinorrhoea is of no consequence.
Fact: Clear rhinorrhoea may be a sign of a cerebrospinal fluid leak and should prompt further urgent assessment.

Management of Septal Haematomas

Myth: Septal haematomas usually resolve spontaneously.
Fact: Septal haematomas should be drained promptly to prevent septal perforation. Antibiotics should be prescribed after drainage.

Referral for Manipulation under Anaesthetic

Myth: The patient should be referred immediately for manipulation under anaesthetic.
Fact: Further reasons for immediate referral include marked nasal deviation, persisting epistaxis, intercanthal widening, facial anaesthesia, facial or mandibular fracture, and ophthalmoplegia.

The NICE guidelines advise referring patients with recurrent epistaxis and a high risk of underlying disorders to ear, nose and throat for investigation. This patient, who is of Chinese origin and has recurrent nosebleeds, nasal obstruction, and weight loss, is at high risk of nasopharyngeal cancer due to his ethnicity and age. The full blood count results show thrombocytosis, which may indicate malignancy. Hereditary telangiectasia and Von Willebrand’s disease are unlikely due to the absence of a family history and the onset of nosebleeds in later life. Nasal polyps do not typically cause epistaxis, but may present with nasal obstruction, postnasal drip, snoring, or obstructive sleep apnoea. The patient’s age rules out angiofibroma as a possible cause, as this benign tumour typically occurs in pre-pubescent and adolescent males and is rare over the age of 25.

Understanding Nasopharyngeal Carcinoma

Nasopharyngeal carcinoma is a type of squamous cell carcinoma that affects the nasopharynx. It is a rare form of cancer that is more common in individuals from Southern China and is associated with Epstein Barr virus infection. The presenting features of nasopharyngeal carcinoma include cervical lymphadenopathy, otalgia, unilateral serous otitis media, nasal obstruction, discharge, and/or epistaxis, and cranial nerve palsies such as III-VI.

To diagnose nasopharyngeal carcinoma, a combined CT and MRI scan is typically used. The first line of treatment for this type of cancer is radiotherapy. It is important to catch nasopharyngeal carcinoma early to increase the chances of successful treatment.

Treatment Options for earwax: Ear Drops, Microsuction, and Manual Removal

earwax, also known as cerumen, can cause discomfort and hearing problems if it builds up in the ear canal. The first-line treatment for earwax is ear drops, which can soften the wax and make it easier to remove. Microsuction is a safer alternative to irrigation, but it is not widely available. Manual removal using a probe is also an option. However, there is little evidence on the effectiveness of these treatments.

Various types of ear drops can be used, including sodium bicarbonate, sodium chloride, olive oil, and almond oil. Cerumol® is a commonly used proprietary agent. However, the British National Formulary warns against using docusate sodium (Waxsol®, Molcer®) or urea hydrogen peroxide (Exterol®, Otex®) as they may irritate the external meatus.

Regardless of the type of ear drop used, the patient should lie with the affected ear uppermost for 5-10 minutes after applying the drops. While using any type of ear drop appears to be better than no treatment, it is uncertain if one type of drop is more effective than another. Therefore, it is important to seek advice from a healthcare professional before attempting to remove earwax at home.

Children who have glue ear and also have Down’s syndrome or cleft palate should be referred to an ENT specialist. While most children with otitis media with effusion (OME) can be observed for 6-12 weeks, those with Down’s syndrome or cleft palate are less likely to recover on their own. It is important to follow up with all patients with OME, even if they do not meet the criteria for referral to ENT.

Antibiotics, antihistamines, and corticosteroids should not be prescribed for OME as there is no evidence to support their use. If the patient did not have Down’s syndrome, it would be appropriate to recheck their ears after 6-12 weeks and refer to ENT if the OME had not resolved. During this observation period, normal activities including swimming (except for diving) should be encouraged.

Understanding Glue Ear

Glue ear, also known as serous otitis media, is a common condition among children, with most experiencing at least one episode during their childhood. It is characterized by the accumulation of fluid in the middle ear, leading to hearing loss, speech and language delay, and behavioral or balance problems. The risk factors for glue ear include male sex, siblings with the condition, bottle feeding, day care attendance, and parental smoking. It is more prevalent during the winter and spring seasons.

The condition typically peaks at two years of age and is the most common cause of conductive hearing loss and elective surgery in childhood. Treatment options include grommet insertion, which allows air to pass through into the middle ear, and adenoidectomy. However, grommets usually stop functioning after about ten months. It is important to understand the symptoms and risk factors of glue ear to seek appropriate treatment and prevent further complications.

Misconceptions about Tonsillectomy Recovery

Tonsillectomy is a common surgical procedure that involves the removal of the tonsils. However, there are several misconceptions about the recovery process that patients should be aware of.

Firstly, some patients may experience ear pain and halitosis after the surgery. This is due to referred pain from the tonsils and infection of the raw tissue areas, respectively.

Secondly, coughing up small amounts of blood ten days postoperatively is not normal and should be referred to secondary care for possible admission. Secondary bleeds are most common after about 5-10 days, and minor bleeding may be a precursor of a major bleed.

Thirdly, removal of the tonsils doesn’t guarantee a complete cessation of throat infections. Patients may still experience laryngitis or pharyngitis.

Fourthly, a temporary rise in the pitch of the voice is common after tonsillectomy due to swelling in the oropharynx. However, a permanent change in voice is not expected.

Lastly, it is normal to have moderate-to-severe discomfort for up to two weeks after the surgery, including pain while swallowing and pain in the throat. Adequate analgesia is needed, and children may become dehydrated if they do not take in adequate liquids after the surgery.

In conclusion, understanding the misconceptions about tonsillectomy recovery can help patients better prepare for the surgery and manage their expectations during the healing process.

Prominent Ears: Causes, Diagnosis, and Treatment Options

Prominent ears affect a small percentage of the population and are usually inherited. This condition arises due to the lack or malformation of cartilage during ear development in the womb, resulting in abnormal helical folds or lateral growth. While some babies are born with normal-looking ears, the problem may arise within the first three months of life.

Before six months of age, the ear cartilage is soft and can be molded and splinted. However, after this age, surgical correction is the only option. Pinnaplasty or otoplasty can be performed on children from the age of five, but the ideal age for the procedure is around eight years old. This allows enough time to see if the child perceives the condition as a problem, while also avoiding potential teasing or bullying at school.

While some prominent ears may become less visible over time, it is best not to delay corrective procedures. Younger ears tend to produce better results after surgery, and waiting too long may increase the risk of bullying at school. Overall, understanding the causes, diagnosis, and treatment options for prominent ears can help individuals make informed decisions about their care.

Treatment Options for Chronic Gingivitis

Chronic gingivitis is a common condition that can lead to gum inflammation, bleeding, and discomfort. Here are some treatment options for patients with chronic gingivitis:

1. Go to a general dental practitioner: Regular oral hygiene advice and treatment from a general dental practitioner can help manage chronic gingivitis.

2. Avoid prescribing antibiotics: Antibiotics are not indicated for chronic gingivitis, and their overuse can lead to antibiotic resistance.

3. Avoid prescribing mouthwash: While mouthwash can help prevent plaque and gingivitis, it is not effective for established plaque and cannot stop periodontitis from progressing.

4. Consider temporary pain relief: Saline mouthwash can provide temporary pain and swelling relief.

5. Prescribe metronidazole for acute necrotising ulcerative gingivitis: If the patient has punched-out gingival ulcers covered with a white, yellowish, or grey pseudomembrane, metronidazole 400 mg three times daily for one week may be necessary.

6. Refer to oral surgery for severe symptoms or suspicion of malignancy: Referral to oral surgery would only be necessary for severe or rapidly progressive symptoms or suspicion of malignancy.

By following these treatment options, patients with chronic gingivitis can manage their symptoms and improve their oral health.

The individual is experiencing sudden sensorineural hearing loss, which is typically of unknown cause. It is recommended that all patients begin treatment promptly with high dose steroids (60mg/day) for seven days, as this has been shown to improve outcomes. An ENT evaluation should be scheduled immediately to conduct pure tone audiometry testing and to rule out the presence of an acoustic neuroma through an MRI. In cases where oral steroids are ineffective, intra-tympanic steroids may be administered. Aciclovir is not typically prescribed as there is no evidence to support its efficacy.

Rinne’s and Weber’s Test for Differentiating Conductive and Sensorineural Deafness

Rinne’s and Weber’s tests are 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 indicates that BC is better than AC, suggesting conductive deafness.

Weber’s test involves placing a tuning fork in the middle of the forehead equidistant from the patient’s ears and asking the patient 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.

The table below summarizes the interpretation of Rinne and Weber tests. A normal result indicates that AC is greater than BC bilaterally and the sound is midline. Conductive hearing loss is indicated by BC being greater than AC in the affected ear and AC being greater than BC in the unaffected ear, with the sound lateralizing to the affected ear. Sensorineural hearing loss is indicated by AC being greater than BC bilaterally, with the sound lateralizing to the unaffected ear.

Overall, Rinne’s and Weber’s tests are useful tools for differentiating between conductive and sensorineural deafness, allowing for appropriate management and treatment.

Understanding Gingivitis and Periodontal Disease

Gingivitis is a common condition characterized by inflammation of the gums, often caused by dental plaque. If left untreated, it can progress to periodontitis, which affects the ligaments and bone supporting the teeth. Risk factors include poor oral hygiene, smoking, and diabetes. Treatment involves managing oral hygiene and using antiseptic mouthwashes, but it’s important to see a dentist for proper care.

Necrotising ulcerative gingivitis, also known as Vincent’s disease, is a painful form of gingivitis that can cause ulcers and bleeding. It’s caused by bacteria already present in the mouth and can be treated with antibiotics.

Periodontal disease is a common problem in HIV-infected patients and can present as necrotising ulcerative periodontitis or linear gingival erythema. These conditions can occur even in clean mouths with little plaque or tartar.

Bleeding gums can also be a symptom of leukaemia and platelet disorders. It’s important to seek medical attention if you experience persistent bleeding or other oral health issues.

If rotatory nystagmus is observed during the Dix-Hallpike manoeuvre, it is likely that the patient has benign paroxysmal positional vertigo (BPPV). This is supported by the patient’s history of vertigo lasting less than 1 minute when changing head position. The Dix-Hallpike manoeuvre is the recommended examination by NICE to diagnose BPPV and can provoke rotatory upbeat nystagmus.

It is important to note that while the Dix-Hallpike manoeuvre is specific to BPPV, it produces rotatory nystagmus rather than vertical nystagmus. The Epley manoeuvre is used as a treatment for BPPV, not as a diagnostic tool.

Unterberger’s test is not used to diagnose BPPV, but rather to assess vertigo and examine for labyrinth dysfunction, which may be associated with hearing loss and tinnitus.

Benign paroxysmal positional vertigo (BPPV) is a common cause of vertigo that occurs suddenly when there is a change in head position. It is more prevalent in individuals over the age of 55 and is less common in younger patients. Symptoms of BPPV include dizziness and vertigo, which can be accompanied by nausea. Each episode typically lasts for 10-20 seconds and can be triggered by rolling over in bed or looking upwards. A positive Dix-Hallpike manoeuvre, which is indicated by vertigo and rotatory nystagmus, can confirm the diagnosis of BPPV.

Fortunately, BPPV has a good prognosis and usually 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 effectiveness. However, it is important to note that around half of individuals with BPPV may experience a recurrence of symptoms 3-5 years after their initial diagnosis.

The Rinne and Weber tests are utilized to differentiate between conductive and sensorineural hearing loss.

In the case of this individual, there is an obstruction of wax in the right ear canal, which would result in a conductive hearing loss on the right side.

During the Weber test, the patient should be able to locate the sound to the side of a conductive hearing loss, as bone conduction is enhanced. The sound will be located away from a sensorineural hearing loss.

If there is a conductive hearing loss, the Rinne test will be negative, as bone conduction is better than air conduction. It will be positive if air conduction is better than bone conduction, which may be the case for mild-moderate sensorineural hearing loss or if there is normal hearing.

In this instance, the wax blockage causes a conductive hearing loss on the right side. Therefore, during the Weber test, the sound should be localized to the right, and Rinne should be negative on the right side and positive on the left.

Rinne’s and Weber’s Test for Differentiating Conductive and Sensorineural Deafness

Rinne’s and Weber’s tests are 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.

Conductive hearing loss is indicated by BC being greater than AC in the affected ear and AC being greater than BC in the unaffected ear, with the sound lateralizing to the affected ear. Sensorineural hearing loss is indicated by AC being greater than BC bilaterally, with the sound lateralizing to the unaffected ear.

Overall, Rinne’s and Weber’s tests are useful tools for differentiating between conductive and sensorineural deafness, allowing for appropriate management and treatment.

Myths and Facts About Tinnitus

Tinnitus, the perception of sound in the absence of external sound, is a common condition that affects around 10% of adults in the UK. However, there are many myths and misconceptions surrounding this condition.

One myth is that tinnitus may be a sign of a brain tumour. While unilateral tinnitus may be a sign of an acoustic neuroma, this is rare.

Another myth is that tinnitus is usually caused by drugs. While over 200 drugs are reported to cause tinnitus, drugs are not the commonest cause.

A third myth is that there is no treatment for tinnitus. However, a hearing aid can often help, and relaxation techniques or background music may also be beneficial.

Finally, some people believe that tinnitus is rare in the absence of ear disease and that it is usually constant in severity. In fact, tinnitus can have a wide variety of causes and symptoms, and many cases have no identifiable cause. Symptoms may come and go, and most cases of tinnitus are mild and improve over time.

Understanding the Difference between Vestibular Neuronitis and Labyrinthitis

Vestibular neuronitis and labyrinthitis are two conditions that can cause vertigo, but they have different underlying causes and symptoms. Vestibular neuronitis is caused by inflammation of the vestibular nerve, while labyrinthitis is caused by inflammation of the labyrinth. Both conditions often develop after a viral infection and can cause acute onset, spontaneous, prolonged vertigo.

The key difference between the two conditions is that labyrinthitis also causes hearing loss and tinnitus, while hearing is unaffected in vestibular neuronitis and tinnitus doesn’t occur. It is important to differentiate between the two conditions because the treatment and management may differ.

The HiNTs exam is a helpful tool for differentiating between vestibular neuronitis and posterior circulation stroke in cases of acute vertigo. It consists of three steps, with a fourth step recently suggested for detecting AICA infarcts. The exam assesses for nystagmus, skew deviation, head impulse test, and new unilateral hearing loss. A normal head impulse test is concerning and warrants referral to the acute stroke team. While prochlorperazine may be useful for acute peripheral vestibular neuropathy, betahistine is only licensed for Meniere’s disease. As this patient’s symptoms are ongoing, a TIA clinic would not be appropriate, and urgent neuroimaging should be performed before considering high dose aspirin. If there is any diagnostic uncertainty, referral for same-day assessment is necessary.

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 is also a common symptom, but there is no hearing loss or tinnitus.

It is important to differentiate vestibular neuronitis from other conditions such as viral labyrinthitis and posterior circulation stroke. The HiNTs exam can be used to distinguish between these conditions.

Treatment for vestibular neuronitis typically involves medication to alleviate symptoms, such as buccal or intramuscular prochlorperazine for severe cases, or a short course of oral medication for less severe cases. Vestibular rehabilitation exercises are also recommended for patients who experience chronic symptoms.

Understanding the symptoms and treatment options for vestibular neuronitis can help individuals manage this condition and improve their quality of life.

Benign paroxysmal positional vertigo (BPPV) is a common cause of vertigo that occurs suddenly when there is a change in head position. It is more prevalent in individuals over the age of 55 and is less common in younger patients. Symptoms of BPPV include dizziness and vertigo, which can be accompanied by nausea. Each episode typically lasts for 10-20 seconds and can be triggered by rolling over in bed or looking upwards. A positive Dix-Hallpike manoeuvre, which is indicated by vertigo and rotatory nystagmus, can confirm the diagnosis of BPPV.

Fortunately, BPPV has a good prognosis and usually 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 effectiveness. However, it is important to note that around half of individuals with BPPV may experience a recurrence of symptoms 3-5 years after their initial diagnosis.

For a patient presenting with Bell’s palsy and eye symptoms, it is important to commence on a course of prednisolone and provide eye care advice. Lubricating eye drops should be used frequently during the day, eye ointment used at night, and the affected eye should be taped closed at night using microporous tape. Aciclovir may be considered if Ramsay Hunt syndrome is suspected. Referral to an ophthalmologist is advised if the patient reports eye symptoms. Urgent referral to an appropriate specialist is necessary if the patient has worsening neurologic findings, features suggestive of an upper motor neurone cause, features suggestive of cancer, systemic or severe local infection, or trauma. However, none of these features are present in this patient.

Bell’s palsy is a sudden, one-sided facial nerve paralysis of unknown cause. It typically affects individuals between the ages of 20 and 40, and is more common in pregnant women. The condition is characterized by a lower motor neuron facial nerve palsy that affects the forehead, while sparing the upper face. Patients may also experience post-auricular pain, altered taste, dry eyes, and hyperacusis.

The management of Bell’s palsy has been a topic of debate, with various treatment options proposed in the past. However, there is now consensus that all patients should receive oral prednisolone within 72 hours of onset. The addition of antiviral medications is still a matter of discussion, with some experts recommending it for severe cases. Eye care is also crucial to prevent exposure keratopathy, and patients may need to use artificial tears and eye lubricants. If they are unable to close their eye at bedtime, they should tape it closed using microporous tape.

Follow-up is essential for patients who show no improvement after three weeks, as they may require urgent referral to ENT. Those with more long-standing weakness may benefit from a referral to plastic surgery. The prognosis for Bell’s palsy is generally good, with most patients making a full recovery within three to four months. However, untreated cases can result in permanent moderate to severe weakness in around 15% of patients.

Brant Daroff exercises

If a patient has persistent unilateral ear discharge that doesn’t respond to antibiotics, it is important to consider the possibility of cholesteatoma, according to NICE guidelines. A cholesteatoma can be concealed behind wax in the attic, so a referral to an ENT clinic for microsuction and direct inspection is necessary. The urgency of the referral depends on the severity of the patient’s symptoms. In this case, a semi-urgent referral is appropriate, but if the patient experiences more advanced symptoms such as vertigo or facial nerve palsy, an urgent discussion with an on-call ENT specialist is necessary.

While olive oil may be helpful for wax buildup, it is not the main issue in this case, as the patient is experiencing discharge. Oral antibiotics are not recommended as there is no evidence of infection. An MRI of the IAMs may be necessary, but it is best to arrange this as part of an assessment by the ENT service. Ear syringing may be useful for wax buildup, but it is not advisable in this situation.

Understanding Cholesteatoma

Cholesteatoma is a benign growth of squamous epithelium that can cause damage to the skull base. It is most commonly found in individuals between the ages of 10 and 20 years old. Those born with a cleft palate are at a higher risk of developing cholesteatoma, with a 100-fold increase in risk.

The main symptoms of cholesteatoma include a persistent discharge with a foul odor and hearing loss. Other symptoms may occur depending on the extent of the growth, such as vertigo, facial nerve palsy, and cerebellopontine angle syndrome.

During otoscopy, a characteristic attic crust may be seen in the uppermost part of the eardrum.

Management of cholesteatoma involves referral to an ear, nose, and throat specialist for surgical removal. Early detection and treatment are important to prevent further damage to the skull base and surrounding structures.

In summary, cholesteatoma is a non-cancerous growth that can cause significant damage if left untreated. It is important to be aware of the symptoms and seek medical attention promptly if they occur.

The Weber’s test in sensorineural hearing loss indicates that the sound is perceived more strongly in the ear opposite to the affected ear.

Meniere’s disease is a condition that affects the inner ear and its cause is 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 the excessive pressure and progressive dilation of the endolymphatic system. The main symptoms of Meniere’s disease are recurrent episodes of vertigo, tinnitus, and sensorineural hearing loss. Vertigo is usually the most prominent symptom, but patients may also experience 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 is that symptoms usually resolve in the majority of patients after 5-10 years. However, most patients will be left with some degree of hearing loss, and psychological distress is common. ENT assessment is required to confirm the diagnosis, and patients should inform the DVLA as the current advice is to cease driving until satisfactory control of symptoms is achieved. Acute attacks can be managed with buccal or intramuscular prochlorperazine, and admission to the hospital may be required. Prevention strategies include the use of betahistine and vestibular rehabilitation exercises, which may be beneficial.

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 most common features of nasal polyps include nasal obstruction, rhinorrhoea, sneezing, and a poor sense of taste and smell. However, if a patient experiences unilateral symptoms or bleeding, further investigation is always necessary.

If a patient is suspected of having nasal polyps, they should be referred to an ear, nose, and throat (ENT) specialist for a full examination. Treatment typically involves the use of topical corticosteroids, which can shrink polyp size in around 80% of patients. With proper management, most patients with nasal polyps can experience relief from their symptoms.

Angular Stomatitis and Candida Infection

Angular stomatitis is a common condition that is often caused by dryness, chapping, and licking of the lips. It can also be caused by salivation and drooling, which can lead to irritation. Candida infection is a common cause of angular stomatitis, although secondary infection with staphylococcal aureus should also be considered.

When it comes to treatment, the clinical scenario in this case is more in keeping with candida infection. Miconazole cream is usually the first line of treatment for candida infection, while mild topical corticosteroids can be used to treat dermatitis. If the condition is unresponsive to miconazole alone, hydrocortisone can be added.

It’s important to note that contact dermatitis is often a differential diagnosis for angular stomatitis. Aciclovir cream is used for herpes simplex lesions, while fusidic acid can be used to treat small areas of staphylococcal infection. Hydromol is a simple emollient and will not treat candida infections.

In some cases, no treatment is needed, and angular cheilitis resolves by itself. However, most cases are accompanied by superimposed candida infection.
