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