PURPOSE: Obstructive sialadenitis (OS) is a relatively common disease in clinic. This study aimed to explore the relationship between micro-structure and obstructive sialadenitis by sialoendoscopy. METHODS: Between October 2002 and February 2012, 583 patients with obstructive symptoms in submandibular gland (n=492 cases) and parotid gland (n =9 leases) were diagnosed using sialoendoscopy and occlusal films, and the inner features and structure of duct of submandibular and parotid gland were observed and evaluated by sialoendoscopy. RESULTS: Pathological findings were noted in salivary duct in 574 cases (98.5%, 574 of 583), and normal findings were in 9 cases (1.5%, 9 of 583). In submandibular gland, the histological features of 485 cases were identified endoscopically and radiographically, and endoscopic findings were of three types: sialolith (n=439, 89.2%), mucus plug (n=18, 3.7%), and stenosis (n=28, 5.7%). 12 cases were found to have foreign body (fish bone) wrapped by sialolith. Among 89 parotid cases: stenosis accounted for 67, 73.6%, sialolith accounted for 9, 9.9%,mucus plug accounted for 13,14.3%. Opening of sublingual gland, basin-like structure in hilus region, sphincter phenomenon and polyps were found under sialoendoscopic observation. CONCLUSION: Sialoendoscopy is a new technique to detect the cause of obstruction in salivary gland and presume the possible mechanism of obstruction, especially stone formation.
