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