Most likely class? Antidepressants Antibiotics Antihypertensives Anticholinergics Anticholinergics are most common cause of drug-induced xerostomia through muscarinic blockade. 3 / 15 The most reliable test for Sjögren's syndrome diagnosis is Schirmer test Minor gland biopsy Anti-SSA antibodies Salivary flow Minor salivary gland biopsy showing focal lymphocytic sialadenitis has highest specificity for diagnosis. 4 / 15 Child presents with bilateral painful parotid swelling. Most likely cause? Juvenile recurrent parotitis Viral sialadenitis Bacterial infection Stones Viral sialadenitis (commonly mumps) is most common cause of bilateral parotid swelling in children. 5 / 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. 6 / 15 The most common malignant tumor of minor salivary glands is Acinic cell Mucoepidermoid Adenoid cystic Squamous cell Adenoid cystic carcinoma is most common in minor glands, especially palate. Known for perineural invasion. 7 / 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. 8 / 15 Patient presents with rapidly growing parotid mass and facial weakness. Most concerning for? Adenoid cystic carcinoma Warthin tumor Mucoepidermoid carcinoma Pleomorphic adenoma Facial nerve involvement, rapid growth, pain, and fixation strongly suggest malignancy. Requires immediate biopsy. 9 / 15 A 50-year-old man has painful submandibular swelling during meals. Most likely diagnosis? Sialolithiasis Sialadenitis Ranula Tumor Sialolithiasis most commonly affects submandibular gland (80-90%) due to tortuous duct and calcium-rich secretions. 10 / 15 The most appropriate initial imaging for suspected salivary stone is MRI Ultrasound Sialogram CT scan Ultrasound is first-line - no radiation, can visualize stones, assess duct dilation, and guide procedures. 11 / 15 A woman with dry eyes, dry mouth, joint pain. Most likely diagnosis? Arthritis Lymphoma Sjögren's syndrome IgG4 disease Sjögren's syndrome - autoimmune condition affecting salivary and lacrimal glands. Associated with positive SSA/Ro antibodies. 12 / 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. 13 / 15 Patient post-radiation with severe dry mouth. Best initial treatment? Surgery Pilocarpine Artificial saliva Antibiotics Pilocarpine stimulates residual salivary function. Start with salivary substitutes and maintain oral hygiene. 14 / 15 A patient with HIV presents with bilateral parotid enlargement. The most likely underlying pathology is Bacterial infection Lymphoma Viral sialadenitis Lymphoepithelial cysts HIV-associated lymphoepithelial cysts are common in HIV. Presents as bilateral, painless parotid enlargement. 15 / 15 A 45-year-old presents with a painless, slowly growing mass in the parotid. What is the most common benign tumor? Oncocytoma Basal cell adenoma Warthin tumor Pleomorphic adenoma Pleomorphic adenoma is the most common benign tumor (80% of benign parotid tumors). Typically presents as painless, slow-growing mobile mass. Your score is LinkedIn Facebook Twitter 0% Restart quiz
