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