Retromandibular vein Tragal pointer Styloid process Digastric muscle The tragal pointer is a reliable landmark - facial nerve is 1-2cm deep and anterior to it, lying just inferior to the tympanomastoid suture. 2 / 15 A patient with HIV presents with bilateral parotid enlargement. The most likely underlying pathology is Bacterial infection Lymphoma Lymphoepithelial cysts Viral sialadenitis HIV-associated lymphoepithelial cysts are common in HIV. Presents as bilateral, painless parotid enlargement. 3 / 15 A 50-year-old man has painful submandibular swelling during meals. Most likely diagnosis? Ranula Tumor Sialolithiasis Sialadenitis Sialolithiasis most commonly affects submandibular gland (80-90%) due to tortuous duct and calcium-rich secretions. 4 / 15 The most concerning feature of malignant transformation in pleomorphic adenoma is Firmness Rapid growth Facial weakness Pain Rapid growth in longstanding pleomorphic adenoma suggests malignant transformation (carcinoma ex pleomorphic adenoma). 5 / 15 The most common complication of submandibular stone removal is Infection Bleeding Duct stricture Lingual nerve injury Lingual nerve injury is most common due to close anatomical relationship in floor of mouth. 6 / 15 Child presents with bilateral painful parotid swelling. Most likely cause? Viral sialadenitis Bacterial infection Juvenile recurrent parotitis Stones Viral sialadenitis (commonly mumps) is most common cause of bilateral parotid swelling in children. 7 / 15 A 45-year-old presents with a painless, slowly growing mass in the parotid. What is the most common benign tumor? Pleomorphic adenoma Oncocytoma Warthin tumor Basal cell adenoma Pleomorphic adenoma is the most common benign tumor (80% of benign parotid tumors). Typically presents as painless, slow-growing mobile mass. 8 / 15 Which of the following conditions may require immediate surgical treatment? Deep lobe abscess Viral sialadenitis Ranula Sialolithiasis Deep lobe parotid abscess can spread to parapharyngeal space causing airway compromise. Treatment includes broad spectrum antibiotics and drainage. 9 / 15 Patient develops xerostomia after starting new medication. Most likely class? Antibiotics Anticholinergics Antidepressants Antihypertensives Anticholinergics are most common cause of drug-induced xerostomia through muscarinic blockade. 10 / 15 Patient post-radiation with severe dry mouth. Best initial treatment? Artificial saliva Surgery Pilocarpine Antibiotics Pilocarpine stimulates residual salivary function. Start with salivary substitutes and maintain oral hygiene. 11 / 15 The most appropriate initial imaging for suspected salivary stone is CT scan Sialogram Ultrasound MRI Ultrasound is first-line - no radiation, can visualize stones, assess duct dilation, and guide procedures. 12 / 15 Patient presents with rapidly growing parotid mass and facial weakness. Most concerning for? Adenoid cystic carcinoma Mucoepidermoid carcinoma Warthin tumor Pleomorphic adenoma Facial nerve involvement, rapid growth, pain, and fixation strongly suggest malignancy. Requires immediate biopsy. 13 / 15 A woman with dry eyes, dry mouth, joint pain. Most likely diagnosis? Lymphoma IgG4 disease Sjögren's syndrome Arthritis Sjögren's syndrome - autoimmune condition affecting salivary and lacrimal glands. Associated with positive SSA/Ro antibodies. 14 / 15 The most reliable test for Sjögren's syndrome diagnosis is Minor gland biopsy Schirmer test Salivary flow Anti-SSA antibodies Minor salivary gland biopsy showing focal lymphocytic sialadenitis has highest specificity for diagnosis. 15 / 15 The most common malignant tumor of minor salivary glands is Mucoepidermoid Acinic cell Adenoid cystic Squamous cell Adenoid cystic carcinoma is most common in minor glands, especially palate. Known for perineural invasion. Your score is LinkedIn Facebook Twitter 0% Restart quiz
