摘要
During a 9-year period from October 2002 to October 2011, 561 patients with swelling in the submandibular gland (n = 474) and parotid gland (n = 87) were successfully studied using sialendoscopy, and the features and pathological changes of the duct evaluated and recorded. Abnormalities were noted in 552/561 cases (98%), and normal features in 9 (2%). The pathological changes in 467 submandibular glands were identified both endoscopically and radiographically, and endoscopic findings showed 3 types: sialolith (n = 423, 91%), mucus plug (n = 15, 3%), and stenosis (n = 29, 6%). In 12 cases foreign bodies (fish bones) were found fixed in calculi. In 85 parotid glands the main pathological finding in the duct was stenosis (n = 64, 75%, mucus plug (n = 12, 14%), and sialolith (n= 9, 11%). Several microstructures had been found on sialendoscopy, including sublingual opening, a basin-like structure in the hilar region, a sphincter phenomenon, and hyperplasia. Sialendoscopy can give direct information about the salivary duct, and in some cases indicate the possible mechanism of obstruction.
