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