A woman in her early 50s, who is a singer, has a history of thyroid surgery and needs another procedure due to recurrent thyroid carcinoma. Following the surgery, she experiences a change in her voice and is unable to reach high notes while singing. During flexible laryngoscopy, it is observed that her left vocal cord does not elongate during phonation.
Which nerve is likely to have been affected?Your Answer: Recurrent laryngeal nerve
Correct Answer: External branch of the superior laryngeal nerve
Explanation:Nerves Related to the Thyroid Gland and Their Risks in Surgery
The thyroid gland is closely related to several nerves, including the external branch of the superior laryngeal nerve, recurrent laryngeal nerve, ansa cervicalis nerve, hypoglossal nerve, and lingual nerve. During neck dissection or surgery involving the thyroid or submandibular gland, these nerves may be at risk of damage.
The external branch of the superior laryngeal nerve innervates the cricothyroid muscle, which elongates the vocal cords. Damage to this nerve can result in an inability to produce high-frequency notes. The recurrent laryngeal nerve, on the other hand, innervates all intrinsic muscles of the thyroid except the cricothyroid muscle. Its injury can cause hoarseness and difficulty in adducting the vocal cords, leading to an aspiration risk.
The ansa cervicalis nerve is located superiorly to the thyroid and may be unavoidable to divide during surgery. The hypoglossal nerve is found even more superiorly and is at risk in submandibular gland excision and neck dissection. The lingual nerve is also located superiorly and may be at risk in submandibular gland excision, along with the hypoglossal nerve and the marginal mandibular branch of the facial nerve.
In summary, surgeons must be aware of the location and function of these nerves to minimize the risk of damage during thyroid or submandibular gland surgery.

A 20-year-old man presents to his doctor with an enlarging neck mass. His mother had a right adrenal phaeochromocytoma which was successfully removed. The patient is 1.9m tall and weighs 74 kg. During examination, the doctor notices multiple yellowish white masses on the patient's lips and tongue. Three months later, the patient undergoes a total thyroidectomy. Which structure is innervated by the nerve most at risk during this procedure, and is also part of the vagus nerve?
Your Answer: Carotid sinus
Correct Answer: Aortic arch
Explanation:The aortic arch has baroreceptors that send afferent fibers to the vagus nerve. A patient with an enlarging neck mass, a family history of multiple endocrine neoplasia type 2B (MEN2B), and a marfanoid habitus may have medullary carcinoma of the thyroid, which is a feature of MEN2B. Surgery is the definitive treatment, but the recurrent laryngeal nerve, a branch of the vagus nerve, is at risk during thyroidectomy. The chorda tympani innervates the taste sensation to the anterior two-thirds of the tongue, while the lingual nerve and hypoglossal nerve innervate the general somatic sensation and motor function, respectively. The platysma muscle is innervated by cranial nerve VII, and the glossopharyngeal nerve (cranial nerve IX) carries general visceral afferent information from the carotid sinus to the brainstem. The spinal accessory nerve (cranial nerve XI) innervates both the sternocleidomastoid and trapezius muscles.

Question 3
Correct
-
A 57-year-old man comes to his doctor's office with a complaint of ongoing right ear pain and associated hearing loss for several weeks. He denies any significant discharge from his ear and has not experienced any fevers. He reports feeling pain in his jaw that sometimes clicks. During the examination, the doctor observes cerumen in the right ear and no inflammation. The tympanic membrane appears normal. The patient experiences pain when moving his jaw. What is the probable diagnosis?
Your Answer: TMJ dysfunction
Explanation:Differential Diagnosis of Ear Pain and Hearing Loss
Temporomandibular Joint Dysfunction as a Likely Cause of Hearing Loss
When infection is ruled out and cerumen is not the culprit, temporomandibular joint (TMJ) dysfunction becomes a probable diagnosis for ear pain and hearing loss. TMJ dysfunction often involves pain that radiates to the ear through the auriculotemporal nerve and crepitus in the jaw. Treatment options for TMJ dysfunction include rest, massage, relaxation techniques, bite guards, NSAIDs, and steroid injections.
Other Possible Causes of Ear Pain and Discharge
Otitis externa, or inflammation of the external auditory canal, typically presents with watery discharge, pain, and itching. Cholesteatoma, a benign tumor that can erode bone and cause cranial nerve symptoms, produces a foul-smelling white discharge and an inflammatory lesion on otoscopy. Mastoiditis, an infection that spreads from the middle ear to the mastoid air cells, causes fever, swelling, and unilateral ear prominence. Acute otitis media, a common childhood infection, results in sudden ear pain and bulging of the tympanic membrane, which may rupture and release purulent discharge.
Conclusion
Ear pain and hearing loss can have various causes, and a thorough evaluation is necessary to determine the underlying condition. While TMJ dysfunction is a possible diagnosis that requires specific management, other conditions such as otitis externa, cholesteatoma, mastoiditis, and acute otitis media should also be considered and treated accordingly.

A 38-year-old male librarian presents with sudden loss of hearing in both ears. There is no ear pain, history of recent upper respiratory tract infection or history of trauma. He has no past medical history of note and does not take any regular prescribed or over-the-counter medications. Tuning fork testing suggests right side sensorineural hearing loss. Examination of the auditory canals and tympanic membranes is unremarkable, as is neurological examination. He is referred to the acute ear, nose and throat (ENT) clinic. Audiometry reveals a 40 db hearing loss in the right ear at multiple frequencies.
Which of the following represents the most appropriate initial management plan?Your Answer: Arrange an urgent magnetic resonance (MR) of the brain
Explanation:Management of Sudden Sensorineural Hearing Loss
Sudden sensorineural hearing loss (SSNHL) is a medical emergency that requires urgent evaluation and management. Patients with unexplained sudden hearing loss should be referred to an ENT specialist and offered an MRI scan. A CT scan may also be indicated to rule out stroke, although it is unlikely to cause unilateral hearing loss.
Antiviral medication such as acyclovir is not recommended unless there is evidence of viral infection. Antibiotics are also not indicated unless there is evidence of bacterial infection.
The mainstay of treatment for SSNHL is oral prednisolone, which should be started as soon as possible and continued for 14 days. While the cause of SSNHL is often unknown, it is important to consider a wide range of differential diagnoses, including trauma, drugs, space-occupying lesions, autoimmune inner ear disease, and many other conditions. Prompt evaluation and treatment can improve the chances of recovery and prevent further hearing loss.

A 5-year-old child, who was born in Germany, is brought to the General Practitioner (GP) by his mother because of recurrent sinus infections and failure to thrive. She is also concerned that the child has had diarrhoea for a few months, which is not resolving.
During the examination, you notice several shiny, pink masses occupying the nasal canals.
What is the most suitable initial step in treating this patient?Your Answer: Treatment with loratadine
Correct Answer: Testing in which pilocarpine is administered
Explanation:Diagnostic Testing for Nasal Polyps in Children: The Role of Pilocarpine Sweat Test
Nasal polyps in children should raise suspicion of cystic fibrosis (CF), especially when accompanied by other symptoms. The gold standard test for CF diagnosis is the sweat test, which involves administering the direct-acting muscarinic agonist pilocarpine and measuring the chloride content of sweat. Loratadine, a second-generation antihistamine, is not the first step in managing nasal polyps. Genetic testing is more expensive and time-consuming than the sweat test and is not the initial diagnostic choice. Biopsy is not necessary for benign nasal polyps. Bacterial culture is not relevant to the pathology underlying nasal polyps in children.

Sophie is a 6-year-old overweight girl brought in by anxious parents who are worried about her loud snoring and frequent interruptions in breathing which have been getting progressively worse. Although she has difficulty getting up from sleep, she does not have any daytime somnolence. However, her parents have been receiving complaints from the school teachers about her disruptive and inattentive behaviour in class. They have done a lot of research on the Internet and are demanding that Sophie has her tonsils removed. On examination, Sophie has a short, thick neck and grade III tonsils, but no other abnormalities.
Which of the following is the next best step in management?Your Answer: Book the child for an elective adenotonsillectomy as a day procedure
Correct Answer: Order an overnight polysomnographic study
Explanation:Childhood Obstructive Sleep Apnoea: Diagnosis and Treatment Options
Childhood obstructive sleep apnoea (OSA) is a pathological condition that requires proper diagnosis and treatment. A polysomnographic study should be performed before any intervention is undertaken, even though adenotonsillectomy is the treatment of choice for childhood OSA. Childhood OSA is characterised by disordered breathing during sleep, which includes both apnoea and hypopnoea. Symptoms such as mouth breathing, abnormal breathing during sleep, poor sleep with frequent awakening or restlessness, nocturnal enuresis, nightmares, difficulty awakening, excessive daytime sleepiness or hyperactivity and behavioural problems are typically observed.
It is important to reassure parents that snoring loudly is normal in children of this age, and their child’s behaviour pattern will improve as they mature. Elective adenotonsillectomy as a day procedure is an option, but a polysomnographic study should be performed first to confirm the diagnosis.
While dental splints have a small role to play in OSA, they are not the ideal treatment option. Intranasal budesonide is an option for mild to moderate OSA, but it is only a temporising measure and not a proven effective long-term treatment. Therefore, it is important to consider all available treatment options and choose the most appropriate one for each individual case.

A 64-year-old man is undergoing evaluation for hoarseness that has persisted for 6 weeks. He smokes 25 cigarettes a day and has been experiencing a chronic cough for the past 3 months. He denies any episodes of coughing up blood. During an initial examination, an otolaryngologist observes that the right vocal fold is immobile while speaking.
What is the most probable underlying cause?Your Answer: Left superior laryngeal nerve palsy
Correct Answer: Left recurrent laryngeal nerve palsy
Explanation:Differentiating Causes of Left-Sided Vocal Cord Paralysis
Left-sided vocal cord paralysis can be caused by various factors, including nerve damage and stroke. Left recurrent laryngeal nerve palsy is a common cause, resulting in hoarseness due to the vocal cord lying in a paramedian position. This type of nerve damage is often associated with an underlying lung malignancy with mediastinal lymph node involvement. On the other hand, left glossopharyngeal nerve palsy does not affect the larynx, while left superior laryngeal nerve palsy is closely related to the recurrent laryngeal nerve and is also more common on the left side. Cerebrovascular accidents involving the left middle or anterior cerebral artery can also cause vocal cord paralysis, but the history provided does not suggest a stroke. Accurately identifying the cause of left-sided vocal cord paralysis is crucial for appropriate management and treatment.

A 28-year-old man presents with a swelling under the left jaw that comes and goes but leaves a dull ache behind. The problem has been present for around 2 weeks and is getting worse. The pain is most noticeable at mealtimes. In the last day, the swelling has become fixed and he reports an unpleasant taste in his mouth. He smokes five cigarettes a day and drinks ten units of alcohol a week, usually on a Saturday night. On examination, there is a smooth, tender swelling in the superior part of the left anterior triangle and, on inspection of the oral cavity, there is poor dentition and pus present just behind the lower incisors.
Which of the following is the most likely diagnosis?Your Answer: Partial obstruction of the submandibular duct due to a stone
Correct Answer: Submandibular gland infection
Explanation:Submandibular Gland Infection: Causes, Symptoms, and Management
A submandibular gland infection is often caused by the presence of a stone in the left submandibular duct, which can lead to a secondary infection due to the stasis of gland secretions. Stones are more common in the submandibular gland due to the length and tortuosity of the duct. Symptoms include a smooth, tender swelling, pain worse at mealtimes, and pus behind the lower incisors. Management involves antibiotics to treat the infection and referral to an ENT or oral surgeon for stone removal, which can usually be done under local anesthesia. In some cases, excision of the entire submandibular gland may be necessary. It is important to note that the presence of bacterial infection indicates an ongoing issue beyond just the stone. Other conditions, such as gingivostomatitis and dental abscess, can cause similar symptoms but have different underlying causes. Mumps, on the other hand, can cause swelling of the parotid gland, not the submandibular gland.

A 65-year-old man, who presented to the Emergency Department a day before for uncontrollable epistaxis, has been admitted following Ear, Nose and Throat (ENT) referral. Bleeding was located and managed by posterior nasal packing. He had no complications following the procedure. However, on the next day, he developed fever, myalgia, hypotension, rashes in the oral mucocutaneous junctions, generalized oedema and several episodes of watery diarrhoea, with nausea and vomiting.
Which of the following investigations/findings would help you make a diagnosis?Your Answer: Non-blanching purpuric rash
Correct Answer: Culture and sensitivity of posterior nasal swab
Explanation:Interpreting Clinical Findings in a Patient with Posterior Nasal Swab Procedure
Toxic shock syndrome (TSS) is a potential complication of an infected posterior nasal swab in the management of epistaxis. Clinical signs and symptoms of multiorgan involvement, along with a positive swab from the posterior pharyngeal mucosa, would be diagnostic for TSS caused by Staphylococcus aureus. Blood cultures are not necessary for diagnosis, as they are positive in only 5% of cases. Eosinophilia is not characteristic of TSS, but rather a hallmark of drug reactions with eosinophilia and systemic symptoms (DRESS). Kawasaki’s disease, another systemic inflammatory disease, is characterised by an increase in acute phase reactants (ESR, CRP) and localised oedema. A non-blanching purpuric rash is typically seen in meningococcal infection and does not match with the clinical features and history of posterior nasal swab procedure in this patient.

The patient in the picture has a slow-growing facial lump and has been referred to the Ear, Nose and Throat (ENT) Outpatient Clinic. He denies any other symptoms and is in good health. Radiology confirms a parotid swelling. What is the most likely pathology he has?
Your Answer: Adenocarcinoma of the parotid
Correct Answer: Pleomorphic adenoma
Explanation:Possible Parotid Gland Conditions and Their Characteristics
The parotid gland is a salivary gland located in front of the ear. It can be affected by various conditions, including pleomorphic adenoma, lymphoma, parotid adenitis, parotid abscess, and adenocarcinoma.
Pleomorphic adenoma is the most common tumour of the parotid gland. It is a slow-growing, mixed benign tumour that can potentially become malignant and has a high chance of recurrence. Surgical removal through a parotidectomy is the current treatment approach.
Lymphoma is a possibility in the parotid gland, but it is less common than pleomorphic adenoma. Patients with lymphoma may have constitutional symptoms, such as night sweats, weight loss, and fever.
Parotid adenitis is inflammation of the parotid gland, which can occur for various reasons. It may be unilateral or bilateral, as seen in mumps. Inflammatory conditions typically cause more tenderness than swelling.
Parotid abscess is a collection of pus in the parotid gland. However, the unusual shape of the gland in combination with normal overlying skin is not typical of abscesses or inflammation.
Adenocarcinoma of the parotid gland is a malignant tumour that can involve the facial nerve. However, the lack of facial nerve involvement and the relative size of the tumour make adenocarcinoma unlikely in this case.
In summary, the characteristics of each condition can help differentiate between them, and a proper diagnosis is crucial for appropriate treatment.

A 38-year-old man with a tumour of the left submandibular gland underwent surgery. While operating on the left submandibular gland, the lingual nerve was damaged. What is the most probable postoperative complaint of the patient?
Your Answer: Loss of general sensation over the posterior third of the left side of the tongue
Correct Answer: Loss of taste sensation over the anterior two-thirds of the left side of the tongue
Explanation:Understanding Lingual Nerve Injury: Effects on Tongue Sensation and Movement
The lingual nerve is a crucial component of the mandibular nerve, responsible for providing sensory innervation to the anterior two-thirds of the tongue and floor of the mouth. It also carries taste sensation fibers from the facial nerve via the chorda tympani special sensory nerves. Injuries to the lingual nerve can result in numbness, dysesthesia, paraesthesiae, and dysgeusia, affecting the anterior two-thirds of the tongue on the same side. Such injuries can occur during invasive dental and surgical procedures.
However, it is important to note that the lingual nerve does not contain a motor component, and thus, it does not affect tongue movement. Deviation of the tongue to either side is not expected in cases of lingual nerve injury.
It is also worth noting that the lingual nerve only supplies sensation to the anterior two-thirds of the tongue. The posterior third of the tongue, on the other hand, is supplied by the glossopharyngeal nerve. Therefore, lingual nerve injury does not affect general sensation in the posterior third of the tongue.

A 12-year-old girl is brought to the Ear, Nose and Throat (ENT) Outpatient Department by her mother who informs the Consultant of her repeated nosebleeds. She is an avid basketball player, and her mother has noticed multiple bruises after games. The Consultant goes through the list of recent laboratory investigations ordered by the girl’s Paediatrician. Full blood count (FBC), haemoglobin, platelet count, white blood cell count and clotting times [prothrombin time (PT), partial thromboplastin time (PTT)] were all found to be within normal values. Additional haematological test results were also normal, including activity assays for factor VIII and XIII, platelet aggregation assay and von Willebrand factor (vWF) antigen.
Which of the following physical findings would give the most effective information regarding her diagnosis?Your Answer: Hypermobility of fingers and toes
Explanation:Possible Diagnoses for Bleeding Problems with Normal Haematological Values
Introduction:
Bleeding problems with normal haematological values can be challenging to diagnose. This article discusses possible diagnoses for such cases based on physical findings.Hypermobility of Fingers and Toes:
Ehlers–Danlos syndrome, a collagen-based disorder, is a possible diagnosis for bleeding problems with normal haematological values. This is associated with hypermobility of the fingers and toes, ocular cutaneous haemorrhages, joint hypermobility, and increased skin elasticity.Subconjunctival Haemorrhages:
Subconjunctival haemorrhages can be caused by ocular or systemic factors. Systemic causes include hypertension, diabetes, and bleeding disorders. It is difficult to diagnose the specific cause without further investigation.Bruises in the Shins:
Easy bruising of the skin can be attributed to platelet disorders, drugs, and hepatic disorders. However, since the coagulation profiles and levels of clotting factors are normal, it is difficult to diagnose the specific cause. Further investigation is necessary.Petechial Rashes on Pressure Sites:
Petechial rashes, conjunctival haemorrhages, and bruising over the shins can indicate an associated bleeding disorder. However, normal haematological values make it difficult to diagnose a specific condition.Visual Acuity Defects and Albinism:
Normal haematological values do not rule out bleeding disorders. Hermansky–Pudlak syndrome, an autosomal recessive condition, can cause visual acuity defects and albinism along with bleeding tendencies. However, the platelet aggregation assay is typically deranged in these cases, which is not the case in this scenario.Possible Diagnoses for Bleeding Problems with Normal Haematological Values and Associated Physical Findings

A 52-year-old woman with a history of intermittent ringing sound in her left ear for the last six months presents to the Ear, Nose and Throat (ENT) Outpatient Department. She describes the ringing sound to be pulsatile in nature. She has no history of fever, hearing loss, trauma or any recent ear infections. Her past medical history includes a diagnosis of multiple sclerosis under remission for the past two years. Clinical examination of the head and neck is unremarkable.
Which is the most appropriate investigation which will help to reach a final diagnosis in this patient?Your Answer: Weber’s test
Correct Answer: Computerised tomography (CT) (contrast-enhanced) scan of the temporal bone
Explanation:Investigating Pulsatile Tinnitus in a Patient with Multiple Sclerosis
Pulsatile tinnitus, a constant ringing or humming sound perceived in the absence of actual sound, can be psychologically debilitating to the patient. In a patient with multiple sclerosis, pulsatile tinnitus may be caused by spontaneous spasm of middle ear muscles. The National Institute for Health and Care Excellence (NICE) recommends imaging for all patients with pulsatile tinnitus to identify the underlying cause. In this case, contrast-enhanced CT scanning of the temporal bone is the best investigation to identify middle ear/osseous pathology. Tympanometry and otoscopy can also be valuable initial investigations for suspected middle ear pathologies. Magnetic resonance angiography is not the best investigation in this scenario as the patient’s history suggests a muscular cause of pulsatile tinnitus. Weber’s test is not relevant in this case as the patient does not report any hearing loss.

A 47-year-old woman presents with a lump in the upper anterior triangle of her neck. She reports that it has been present for a few weeks and only started to bother her after a friend pointed it out. She denies any other symptoms such as weight loss or fevers. She recalls her mother having a similar swelling removed but does not remember the diagnosis. On examination, there is a small, smooth, non-tender, mobile lump. The skin overlying the lump appears normal, and it does not move on swallowing or tongue protrusion. What is the most likely diagnosis?
Your Answer: Sebaceous cyst
Explanation:Differentiating between various types of lumps and bumps on the body
When it comes to lumps and bumps on the body, it can be difficult to determine what they are and whether they require medical attention. Here are some common types of lumps and their characteristics to help differentiate between them.
Sebaceous cysts are small, smooth lumps that are caused by a blocked hair follicle. They are attached to the skin and may have a central punctum with a horn on top. If infected, they can become tender and the skin over them may become red and hot. Excision may be necessary if they are unsightly or infected.
Lipomas are deep to the skin and are typically soft, doughy, and mobile. An ultrasound or biopsy may be necessary to rule out sarcoma or liposarcoma.
Thyroid masses may be indicative of thyroid carcinoma or goitre. A thyroid malignancy would typically be hard, firm, and non-tender, while a goitre can be smooth or multinodular. Symptoms associated with thyroid disease may also be present.
Sternocleidomastoid tumors are congenital lumps that appear within the first few weeks of life and are located beneath the sternocleidomastoid muscle. They can restrict contralateral head movement.
It is important to seek medical attention if any lump or bump is causing discomfort or changes in appearance.

A 12-year-old girl presents to the General Practitioner with severe right ear pain, swelling, and itching. Her mother reports that it all started after her daughter began swimming lessons two months ago. During examination, the clinician notes tenderness when pulling the right ear upwards. Otoscopy is challenging due to the painful, swollen ear canal and white discharge. Additionally, the girl has tender cervical lymph nodes on the right side below the ear and experiences pain when moving her jaw sideways. She has a mild fever (38.3 °C), but the rest of the examination is unremarkable. What is the most appropriate management for this condition?
Your Answer: Oral aminoglycosides
Correct Answer: Topical acetic acid 2% spray (with wick placement) and oral antibiotics
Explanation:The recommended treatment for this patient’s severe otitis externa involves a combination of topical acetic acid 2% spray with wick placement and oral antibiotics. The use of wick placement is necessary due to the swelling in the ear canal, which can hinder the effectiveness of the topical solution. Oral antibiotics are necessary in cases where the infection has spread to adjacent areas, as evidenced by the patient’s tender cervical lymphadenopathy. Flucloxacillin or clarithromycin are commonly used for severe cases. Cleaning and irrigation of the ear canal may be performed under otoscope guidance to remove debris and promote better absorption of topical medication. Oral aminoglycosides are effective but should only be used if the tympanic membrane is intact. NSAIDs can provide symptomatic relief but are not sufficient for treating severe otitis externa. While topical acetic acid 2% spray is a first-line treatment for mild cases, a combination of topical therapy and oral antibiotics is necessary for severe cases.

A 48-year-old woman presents with a 10-day history of fever, sinus pain and fullness, bilateral yellow nasal discharge and difficulty smelling. Prior to this episode she describes having a minor cold, with sore throat and clear nasal discharge. She has no past medical history. On examination, her temperature is 38.2 °C and there is mild tenderness to palpation over the maxillofacial area. There are no nasal polyps. Her throat appears normal.
What should be included in the management of this patient's condition?Your Answer: IV antibiotics
Correct Answer: Paracetamol
Explanation:Managing Acute Sinusitis: Treatment Options and Antibiotic Use
Acute sinusitis is a common condition that can cause discomfort and pain. Self-care measures such as paracetamol or ibuprofen can be used to manage symptoms of pain or fever. However, if symptoms persist for around ten days or more without improvement, a high-dose nasal corticosteroid may be prescribed for 14 days. While nasal corticosteroids may improve symptoms, they are not likely to affect how long they last and could cause systemic effects.
IV antibiotics should only be used in severe cases of systemic infection, intraorbital or periorbital complications, or intracranial complications. Systematic reviews and meta-analyses have shown that antibiotics, when compared with placebo, did not significantly increase the proportion of people in whom symptoms were cured or improved at 3–5 days follow-up. At 7–15 days follow-up, moderate quality evidence showed a statistically significant difference in effectiveness, but the clinical difference was small. This was not evident in the longer term.
For acute sinusitis following a cold, symptoms for <10 days are more commonly associated with a cold rather than viral or bacterial acute sinusitis. Prolonged symptoms (for around ten days or more without improvement) can be caused by either viral (more likely) or bacterial acute sinusitis. Only 0.5–2% of viral sinusitis is complicated by bacterial infection. Even then bacterial sinusitis is usually self-limiting and does not routinely need antibiotics. There is no evidence that topical antibiotics are useful in acute or chronic sinusitis. Understanding Treatment Options and Antibiotic Use for Acute Sinusitis

A 45-year-old man visits his GP complaining of a lump under his chin that causes him pain and swelling, especially after eating a big meal. The facial nerve appears to be functioning normally. Upon examination, there is a tender swelling in the submandibular triangle.
What is the most probable diagnosis?Your Answer: Adenoid cystic carcinoma
Correct Answer: Sialolithiasis
Explanation:Differential Diagnosis of Submandibular Swelling: Understanding the Causes
Submandibular swelling can be caused by various conditions, and it is important to understand the differential diagnosis to provide appropriate treatment. One of the most common causes is sialolithiasis, which is the formation of stones within the salivary glands. This condition obstructs the salivary ducts and can lead to infection, resulting in pain and swelling after eating. Sialolithiasis is more common in men over the age of 40 and typically affects the submandibular gland.
Sjögren syndrome is an autoimmune condition that causes dry mouth, dry eyes, and swelling of the salivary glands, usually bilaterally. However, unilateral acute pain and swelling after eating are more typical of a salivary stone, rather than Sjögren syndrome.
Pleomorphic adenomas are benign tumors that usually present as a painless lump, slowly enlarging over time. They do not typically cause acute pain and swelling.
Warthin’s tumor is another slow-growing lump that is commonly found in the tail of the parotid gland. Unlike sialolithiasis, it does not cause pain.
Adenoid cystic carcinoma is a malignant tumor that presents as a slowly enlarging mass over the parotid area. It does not typically cause pain, but if left unchecked, it can invade local structures such as the facial nerve.
In conclusion, understanding the differential diagnosis of submandibular swelling is crucial for proper diagnosis and treatment. Sialolithiasis, Sjögren syndrome, pleomorphic adenomas, Warthin’s tumor, and adenoid cystic carcinoma are all potential causes, and each requires a different approach to management.

A surgeon prepares to excise the submandibular gland for a suspected malignancy in a pediatric patient. He incises the skin and the platysma in the neck below the gland, then proceeds to dissect the gland free of its bed. As he dissects the deep lobe, he notes the submandibular duct, which he mobilises, ligates and cuts anteriorly.
When cutting the duct, which of the following needs the most care to be taken to avoid damage?Your Answer: The lingual nerve
Explanation:Anatomy of the Submandibular Gland and Related Structures
The submandibular gland is composed of a superficial and deep part, with the facial artery passing between the gland and mandible and the facial vein indenting it superiorly. To access the deep lobe of the gland, both structures must be ligated and cut. The mandibular branch of the facial nerve is at risk of damage during the initial incision, while the lingual nerve is closely related to the submandibular duct and carries various fibers. The facial artery and vein may also be ligated during dissection, but are not as intimately related to the duct as the lingual nerve. The lesser petrosal branch of the glossopharyngeal nerve carries parasympathetic supply to the parotid gland and synapses in the otic ganglion.

On examination, her 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: Epley manoeuvre
Explanation:Management Options for Benign Paroxysmal Positional Vertigo (BPPV)
Benign paroxysmal positional vertigo (BPPV) is a common condition that can cause dizziness and vertigo. The best first-line management option for BPPV is the Epley manoeuvre, which 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 prochlorperazine or betahistine may help with symptoms in the short term, but they do not treat the underlying cause. Vestibular retraining exercises, such as Brandt-Daroff exercises, can also be effective if symptoms persist despite the Epley manoeuvre.

A 5-year-old boy is presented to a paediatrician with a cystic mass on the right lateral aspect of his neck, just below the angle of the jaw. The mother reports intermittent discharge from a small pit located just in front of the lower anterior border of the sternocleidomastoid muscle. What is the cause of this cyst, resulting from the failure of proliferation of which mesenchyme?
Your Answer: Third pharyngeal arch
Correct Answer: Second pharyngeal arch
Explanation:During embryonic development, the pharyngeal arches give rise to various structures in the head and neck. The second arch forms the external auditory meatus and can sometimes lead to the formation of a branchial cleft cyst. The third arch becomes the common carotid artery and gives rise to the stylopharyngeus muscle. The first arch becomes the maxillary and mandibular prominences and gives rise to the muscles of mastication. The fourth arch forms the laryngeal cartilages and is innervated by the superior laryngeal branch of the vagus nerve. The fifth arch regresses quickly. Understanding the development of these arches is important in understanding the anatomy and function of the head and neck.

A 30-year-old woman presents with deteriorating hearing during pregnancy. There is no known family history of hearing loss. Upon examination, the tympanic membrane appears intact and pure tone audiometry indicates a conductive hearing loss with a Carhart notch.
What is the most probable location of the issue?Your Answer: Malleus
Correct Answer: Stapes
Explanation:Understanding Otosclerosis: Diagnosis and Treatment Options
Otosclerosis is a common autosomal dominant disorder that causes a conductive hearing loss, which typically worsens during pregnancy. The condition is caused by the fixation of the stapes bone in the ear, and it exhibits incomplete penetrance, meaning it can skip generations, and there may not be a positive family history of the condition.
Diagnosis of otosclerosis is typically made through examination findings and audiometry results. The Carhart notch, a dip seen on bone conduction audiometry, is a sign that is classically associated with otosclerosis. However, the tympanic membrane is unlikely to be the site of abnormality as it is mentioned that the tympanic membrane is intact on examination.
Treatment options for otosclerosis include amplification with hearing aids and medical treatment with sodium fluoride, which slows progression. Surgery, such as stapedectomy or stapedotomy, is becoming more popular and effective.
It is important to understand the diagnosis and treatment options for otosclerosis to effectively manage the condition and improve quality of life for those affected.

A 42-year-old receptionist presents to the Ear, Nose and Throat (ENT) Clinic for a follow-up visit. She experiences sudden-onset bouts of vertigo and tinnitus that are debilitating and leave her confined to bed until the episode subsides. The initial episode occurred 5 years ago and since then she has noticed a slight decrease in hearing in her left ear. She has undergone a thorough evaluation, and an MRI scan revealed no abnormalities.
What is the probable diagnosis for this patient's condition?Your Answer: Benign paroxysmal positional vertigo (BPPV)
Correct Answer: Ménière’s disease
Explanation:Distinguishing between Ménière’s Disease and Other Causes of Vertigo
Ménière’s disease is a condition characterized by episodic vertigo, tinnitus, and hearing loss. Patients may also experience a sense of fullness or pressure in the ear before an attack. While initially unilateral, Ménière’s can progress to become bilateral and cause a fluctuating, progressive sensorineural hearing loss and permanent tinnitus. Multiple sclerosis and acoustic neuroma can cause similar symptoms, but can be ruled out with a normal MRI scan. Benign paroxysmal positional vertigo (BPPV) can also cause vertigo and nystagmus, but is less severe and does not include tinnitus or hearing loss. Labyrinthitis may cause similar symptoms, but is typically characterized by sudden-onset, severe, constant vertigo that lasts for several weeks, whereas Ménière’s attacks are episodic. Accurately distinguishing between these conditions is important for proper diagnosis and treatment.

A 62-year-old man comes to his GP complaining of bothersome tinnitus that has been going on for 6 weeks. He reports hearing a ringing noise in his left ear only and experiencing hearing loss on the left side. The noise is intrusive and is causing him to have trouble sleeping at night. He denies experiencing any vertigo, headache, or other neurological symptoms. He has a medical history of hypertension and takes atenolol for it.
Upon examination, his ears appear normal.
What is the best course of action for managing this patient's symptoms?Your Answer: Refer routinely to ENT
Correct Answer: Refer urgently to ENT
Explanation:Unilateral Tinnitus: Red Flags and Treatment Options
Unilateral tinnitus is a rare but concerning symptom that should always warrant urgent referral to an ENT specialist. It may indicate an underlying condition such as acoustic neuroma, cerebellopontine angle tumor, glomus tumor, or Ménière’s disease. Other red flag symptoms include pulsatile tinnitus, tinnitus with significant vertigo or asymmetric hearing loss, tinnitus causing psychological distress, and tinnitus with significant neurological symptoms or signs.
Vestibular retraining, an exercise-based treatment program, can help manage vertigo in patients with tinnitus. However, medication has no direct role in treating tinnitus, although it can be used to alleviate associated symptoms such as anxiety or depression.
It is important to note that there is no conventional or complementary medication that has been proven to have specific tinnitus-ameliorating qualities. In fact, repeatedly trying unsuccessful therapies may worsen tinnitus. Therefore, it is crucial to seek prompt medical attention and follow the recommended treatment plan.

A 68-year-old woman presents to her General Practitioner with her husband who has noticed a gradual decrease in hearing on her left side over the past six months. She also reports difficulty walking and a tendency to lean towards the left side. Upon referral to the ENT Department, the Consultant observes nystagmus and dysdiadochokinesia, as well as sensorineural loss in her left ear. What is the most suitable diagnostic test for this patient?
Your Answer: Magnetic resonance imaging (MRI)
Explanation:Diagnostic Tests for Acoustic Neuroma: An Overview
Acoustic neuroma is a type of tumor that affects the vestibular nerve and can cause symptoms such as unilateral hearing loss and unsteady gait. To diagnose this condition, several diagnostic tests are available.
Magnetic resonance imaging (MRI) is the most reliable 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 can provide prognostic information on post-operative hearing loss, but it cannot detect all cases of acoustic neuroma. Otoscopy is of limited or no value in cases of sensorineural deafness.
Pure tone audiometry (PTA) is the best initial screening test for acoustic neuroma, as only 5% of patients will have a normal test. Brainstem-evoked response audiometry can be used as a further screening measure in patients with unexplained asymmetries on standard audiometric testing.
Vestibular testing has limited utility as a screening test for acoustic neuroma, but a decreased or absent caloric response on the affected side may be seen in some cases. Overall, a combination of these tests can help diagnose acoustic neuroma and guide treatment decisions.

A 6-year-old asylum seeker from Africa presents to the Surgical Outpatient Clinic with a mass on the right side of his neck that has been growing in size. On examination, a mass is found on the side of the neck, behind the sternocleidomastoid muscle, which transilluminates brightly. What is the most probable diagnosis?
Your Answer: Laryngocoele
Correct Answer: Cystic hygroma
Explanation:Differentiating Neck Abnormalities: Cystic Hygroma, Laryngocoele, Cervical Rib, Branchial Cyst, and Enlarged Lymph Node
Neck abnormalities can be challenging to differentiate, but understanding their characteristics can aid in proper diagnosis. Cystic hygromas are lymphatic abnormalities that are commonly found in the posterior triangle of the neck and transilluminate. They may not be noticeable at birth but typically grow as the child grows. Laryngoceles are abnormal cystic dilatations of the saccule or appendix of the laryngeal ventricle, which communicate with the lumen of the larynx and are filled with air. They are usually benign but can cause airway obstruction. Cervical ribs are extra ribs that arise from the seventh cervical vertebra and are located above the first rib. They do not transilluminate. Branchial cysts are remnants of the second branchial cleft and occur along the anterior border of the sternocleidomastoid, most commonly at the junction of the lower and middle thirds of the muscle. They do not transilluminate. Enlarged lymph nodes are usually secondary to an infection and settle to normal size after six to eight weeks. Understanding the characteristics of these neck abnormalities can aid in proper diagnosis and treatment.

A 38-year-old man presents with a one-month history of feeling a lump in his throat. The feeling comes and goes and has not progressed. He has no difficulty swallowing food or liquids; in fact, eating and drinking help to relieve the symptoms. He has not lost weight. He is a non-smoker. He was recently diagnosed with gastro-oesophageal reflux disease (GORD) and is taking a proton pump inhibitor. He also has chronic sinusitis, for which he takes a steroid nasal spray.
Examination is normal, without cervical lymphadenopathy.
What is the most likely diagnosis in this case?Your Answer: Achalasia
Correct Answer: Globus pharyngeus
Explanation:Globus pharyngeus is a condition where patients feel a painless lump at the back of their throat. The cause of this condition is unknown, but it is often attributed to anxiety, pharyngeal spasm, reflux disease, or hiatus hernia. However, it is important to rule out more serious conditions such as thyroid disorders or cancer before diagnosing globus pharyngeus. An oesophageal ring is a benign structure at the lower end of the oesophagus that can cause swallowing difficulties. While not always symptomatic, patients may experience regurgitation and food obstruction. A diagnosis is confirmed through upper gastrointestinal endoscopy to rule out more serious causes such as oesophageal cancer. Achalasia is a disorder of the oesophagus where the lower oesophageal sphincter fails to relax, causing difficulty swallowing and regurgitation. A barium swallow and manometry can confirm the diagnosis. Eosinophilic oesophagitis is an allergic reaction that causes pain and heartburn upon swallowing, as well as vomiting and loss of appetite. Laryngeal squamous cell carcinoma is a type of head and neck cancer associated with smoking and other carcinogens. Symptoms include hoarseness, coughing, difficulty swallowing, and systemic signs of distant metastases. However, the patient in question had no warning signs or risk factors for this type of cancer.

A 16-year-old boy comes to the Emergency Department after being involved in a fight. He reports being punched on his left ear and has since lost hearing in that ear. He has a GCS score of 15 and has been coherent and lucid throughout the incident. He experiences a mild headache but has not vomited or felt drowsy. On examination, there are no focal neurological signs, and his cervical spine is not tender. Fundoscopy reveals a normal retina, but there is a ruptured left tympanic membrane with a small amount of blood. What is the most appropriate course of action?
Your Answer: Refer him urgently to Ear, Nose and Throat (ENT) for a tympanoplasty
Correct Answer: Give him a week’s course of co-amoxiclav, and advise him to keep his ear dry and to see his general practitioner in 6 weeks
Explanation:Managing a Ruptured Tympanic Membrane: Treatment Options
A ruptured tympanic membrane can occur due to otitis media or trauma. In most cases, the membrane heals on its own within six weeks. To promote healing, it is important to keep the ear dry and avoid exposing it to potentially contaminated water.
Treatment options for a ruptured tympanic membrane depend on the severity of the condition. In most cases, a week’s course of co-amoxiclav is sufficient. However, if symptoms persist after six weeks, referral to an Ear, Nose and Throat (ENT) specialist may be necessary for a tympanoplasty.
There is no need for neurosurgical intervention or a CT scan unless there are complications or signs of an intracranial bleed. Overall, prompt treatment and careful management can help ensure a full recovery from a ruptured tympanic membrane.

A patient with persistent sinusitis is scheduled for endoscopic surgery to address any blockages in the drainage pathways and perform balloon catheter dilation of the paranasal sinus openings. During the procedure, the surgeon aims to access the middle meatus of the nasal cavity to insert a cannula into the ostia.
Which of the paranasal sinuses empties into the sphenoethmoidal recess?Your Answer: Middle ethmoidal sinus
Correct Answer: Sphenoidal sinus
Explanation:Sinus Drainage Pathways in the Nasal Cavity
The nasal cavity contains several sinuses that drain into different areas of the cavity. The sphenoidal sinus drains into the sphenoethmoid recess, which is located posterior and superior to the superior concha. The anterior ethmoidal sinus drains into the middle meatus via the semilunar hiatus, as does the maxillary sinus. The frontal sinus, on the other hand, drains into the infundibulum of the middle meatus. Finally, the middle ethmoidal sinus drains to the ethmoid bulla of the middle meatus. Understanding these drainage pathways is important for diagnosing and treating sinus issues.

A 50-year-old woman comes to her GP complaining of a sore throat, coryzal symptoms, cough, feeling feverish and general malaise for the past week. She reports that she is eating and drinking well. Upon examination, her temperature is 37.1°C and her chest is clear. Her tonsils are inflamed, but there is no exudate. She has no significant medical history except for carpal tunnel syndrome. Based on her Fever PAIN score, what is the most suitable course of action?
Your Answer: Reassure and send home
Correct Answer: Safety net and review in 1 week if no improvement
Explanation:Using the FeverPAIN Score to Determine Antibiotic Use in Pharyngitis
Pharyngitis, or sore throat, is a common reason for patients to seek medical attention. However, not all cases of pharyngitis require antibiotics. In fact, inappropriate antibiotic use can lead to antibiotic resistance and other negative outcomes. To help providers determine which patients with pharyngitis have streptococcal pharyngitis, the FeverPAIN Score was developed.
The FeverPAIN Score assesses five factors: fever, presence of pus, how quickly symptoms attenuate, inflamed tonsils, and cough. A score of 0-1 is associated with a low likelihood of streptococcal infection, while a score of 4 or more is associated with a high likelihood. For patients with a score of 2 or 3, delayed antibiotic use may be appropriate.
In the case of a woman with inflamed tonsils, her FeverPAIN Score indicates that antibiotics are not necessary. However, it is important to safety net patients and review their condition in one week if there is no improvement. By using the FeverPAIN Score, providers can make informed decisions about antibiotic use in pharyngitis and help reduce the risk of antibiotic resistance.

A 28-year-old patient presents with a lump in the neck. On examination, there is a 2-cm smooth, round lump at the anterior border of the upper third of the sternocleidomastoid muscle.
Which of the following is the most likely diagnosis?Your Answer:
Correct Answer: Branchial cyst
Explanation:Common Neck Swellings and Their Characteristics
There are several types of neck swellings that can occur, each with their own unique characteristics. Here are some common neck swellings and their descriptions:
1. Branchial cyst – This type of cyst typically appears as a painless, smooth swelling in young adults. The cause is unknown, but surgical removal is usually recommended to prevent the development of an abscess.
2. Goitre – A goitre, or thyroid lump, is a swelling that rises on swallowing and is usually located in the midline of the neck.
3. Acute parotitis – This condition presents as a painful swelling in front of the ear.
4. Cystic hygroma – These benign cystic structures are typically found in infants and are located in the posterior triangle of the neck.
5. Thyroglossal cyst – This type of cyst is located in the midline of the neck and moves as the tongue protrudes.
It is important to seek medical attention if you notice any unusual swelling in your neck, as some of these conditions may require treatment.
