Most likely diagnosis? Arthritis Lymphoma IgG4 disease Sjögren's syndrome Sjögren's syndrome - autoimmune condition affecting salivary and lacrimal glands. Associated with positive SSA/Ro antibodies. 3 / 15 Patient develops xerostomia after starting new medication. Most likely class? Antihypertensives Antibiotics Anticholinergics Antidepressants Anticholinergics are most common cause of drug-induced xerostomia through muscarinic blockade. 4 / 15 The most reliable test for Sjögren's syndrome diagnosis is Anti-SSA antibodies Schirmer test Minor gland biopsy Salivary flow Minor salivary gland biopsy showing focal lymphocytic sialadenitis has highest specificity for diagnosis. 5 / 15 The most common malignant tumor of minor salivary glands is Mucoepidermoid Squamous cell Adenoid cystic Acinic cell Adenoid cystic carcinoma is most common in minor glands, especially palate. Known for perineural invasion. 6 / 15 During parotidectomy, which structure most reliably identifies the facial nerve trunk? Styloid process Retromandibular vein Tragal pointer 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. 7 / 15 A patient with HIV presents with bilateral parotid enlargement. The most likely underlying pathology is Lymphoepithelial cysts Bacterial infection Lymphoma Viral sialadenitis HIV-associated lymphoepithelial cysts are common in HIV. Presents as bilateral, painless parotid enlargement. 8 / 15 Child presents with bilateral painful parotid swelling. Most likely cause? Stones Juvenile recurrent parotitis Viral sialadenitis Bacterial infection Viral sialadenitis (commonly mumps) is most common cause of bilateral parotid swelling in children. 9 / 15 The most appropriate initial imaging for suspected salivary stone is Ultrasound MRI CT scan Sialogram Ultrasound is first-line - no radiation, can visualize stones, assess duct dilation, and guide procedures. 10 / 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. 11 / 15 A 50-year-old man has painful submandibular swelling during meals. Most likely diagnosis? Sialolithiasis Ranula Tumor Sialadenitis Sialolithiasis most commonly affects submandibular gland (80-90%) due to tortuous duct and calcium-rich secretions. 12 / 15 The most common complication of submandibular stone removal is Bleeding Lingual nerve injury Infection Duct stricture Lingual nerve injury is most common due to close anatomical relationship in floor of mouth. 13 / 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 Oncocytoma Basal cell adenoma Pleomorphic adenoma is the most common benign tumor (80% of benign parotid tumors). Typically presents as painless, slow-growing mobile mass. 14 / 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. 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
