What is the most common benign tumor? Warthin tumor Oncocytoma Basal cell adenoma Pleomorphic adenoma Pleomorphic adenoma is the most common benign tumor (80% of benign parotid tumors). Typically presents as painless, slow-growing mobile mass. 2 / 15 Patient presents with rapidly growing parotid mass and facial weakness. Most concerning for? Mucoepidermoid carcinoma Warthin tumor Pleomorphic adenoma Adenoid cystic carcinoma Facial nerve involvement, rapid growth, pain, and fixation strongly suggest malignancy. Requires immediate biopsy. 3 / 15 The most common complication of submandibular stone removal is Duct stricture Lingual nerve injury Infection Bleeding Lingual nerve injury is most common due to close anatomical relationship in floor of mouth. 4 / 15 Which of the following conditions may require immediate surgical treatment? Sialolithiasis Ranula Deep lobe abscess Viral sialadenitis Deep lobe parotid abscess can spread to parapharyngeal space causing airway compromise. Treatment includes broad spectrum antibiotics and drainage. 5 / 15 A patient with HIV presents with bilateral parotid enlargement. The most likely underlying pathology is Lymphoma Lymphoepithelial cysts Bacterial infection Viral sialadenitis HIV-associated lymphoepithelial cysts are common in HIV. Presents as bilateral, painless parotid enlargement. 6 / 15 A 50-year-old man has painful submandibular swelling during meals. Most likely diagnosis? Ranula Sialadenitis Sialolithiasis Tumor Sialolithiasis most commonly affects submandibular gland (80-90%) due to tortuous duct and calcium-rich secretions. 7 / 15 The most reliable test for Sjögren's syndrome diagnosis is Minor gland biopsy Salivary flow Schirmer test Anti-SSA antibodies Minor salivary gland biopsy showing focal lymphocytic sialadenitis has highest specificity for diagnosis. 8 / 15 Patient post-radiation with severe dry mouth. Best initial treatment? Pilocarpine Artificial saliva Antibiotics Surgery Pilocarpine stimulates residual salivary function. Start with salivary substitutes and maintain oral hygiene. 9 / 15 Child presents with bilateral painful parotid swelling. Most likely cause? Bacterial infection Stones Viral sialadenitis Juvenile recurrent parotitis Viral sialadenitis (commonly mumps) is most common cause of bilateral parotid swelling in children. 10 / 15 Patient develops xerostomia after starting new medication. Most likely class? Antibiotics Antihypertensives Anticholinergics Antidepressants Anticholinergics are most common cause of drug-induced xerostomia through muscarinic blockade. 11 / 15 The most common malignant tumor of minor salivary glands is Adenoid cystic Acinic cell Squamous cell Mucoepidermoid Adenoid cystic carcinoma is most common in minor glands, especially palate. Known for perineural invasion. 12 / 15 A woman with dry eyes, dry mouth, joint pain. Most likely diagnosis? Sjögren's syndrome Lymphoma Arthritis IgG4 disease Sjögren's syndrome - autoimmune condition affecting salivary and lacrimal glands. Associated with positive SSA/Ro antibodies. 13 / 15 The most concerning feature of malignant transformation in pleomorphic adenoma is Rapid growth Facial weakness Pain Firmness Rapid growth in longstanding pleomorphic adenoma suggests malignant transformation (carcinoma ex pleomorphic adenoma). 14 / 15 During parotidectomy, which structure most reliably identifies the facial nerve trunk? Tragal pointer Styloid process Digastric muscle 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. 15 / 15 The most appropriate initial imaging for suspected salivary stone is MRI CT scan Sialogram Ultrasound Ultrasound is first-line - no radiation, can visualize stones, assess duct dilation, and guide procedures.
