Abstract
Although parotid duct obstruction may cause recurrent painful gland swellings, bilateral parotid duct stenosis is rare. Sialendoscopy enables the ductal system to be seen directly, allowing more precise diagnosis of idiopathic gland swelling particularly in stenosis. We report 2 cases involving painful bilateral parotid gland swelling and stenosis. A 61-year-old man with type II (right and left-side) stenosis, and a 35-year-old man with type II (right-side) and III (left-side) stenosis. Both were confirmed in sialendoscopy. Sialendoscopy enables stenosis to be directly and precisely assessed for planning effective treatment.
