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