Results: Three female patients presented with symptoms consistent with obstructive parotitis, including glandular swelling and tenderness with meals and mastication. The 10year-old patient had unilateral facial swelling with mass formation within the masseter muscle and mandible on imaging studies. An acute kinking Stenson’s duct secondary to mass effect could be visualized on salivary endoscopy. The patient’s parotid swelling resolved following debulking of the masseteric space mass that was consistent with fibrous dysplasia on pathological examination. Two patients, ages 49 and 51 years, with bilateral parotid involvement had bilateral masseteric hypertrophy confirmed by imaging and dental wear facets consistent with bruxism on physical examination. Both patients had bilateral kinking of distal Stenson’s duct during jaw closure when visualized with salivary endoscopy. Both patients’ symptoms improved significantly following ultrasound-guided Botox injection of the masseter and nightly use of a bite guard.
