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