Abstract

Objectives: To assess the cohort of patients undergoing sialendoscopic intervention for improvement of symptoms and gland-related quality of life at long-term follow up. Design: retrospective review of medical records with a prospective follow-up by questionnaire. Methods: All patients undergoing sialendoscopy between March 2008 and June 2020 were analyzed in detail regarding indications, technical aspects and postoperative course. To maximize follow-up, patients also received a questionnaire by e-mail. Results: 272 sialendoscopies were performed in 221 patients. Median follow-up time was 37 months. The sialendoscopies were performed in 130 patients for lithiasis, in 66 for stenosis, in 14 for recurrent parotitis of childhood, in 8 for recurrent sialadenitis of unknown origin and in 3 for radio-iodine induced sialadenitis. Complications occurred in 11 of 272 sialendoscopies (4%). Those were iatrogenic perforations, temporary lingual nerve paresthesia and swelling of the floor of the mouth. 53% of patients returned the questionnaire, for a total of 146 evaluable sialendoscopies. The majority of the responders indicated that sialendoscopy had improved their symptoms (83.6%). Salivary glands could be preserved in 89% of the responder group. The highest percentage of patients reporting residual symptoms was found in the RPC group (81.3%) and the lowest in the lithiasis group (16.2%). Besides age, no statistical differences in demographic and pathological features between the responder and non-responder groups were found, supporting generalization of the responders’ results to the entire cohort. Conclusions: This study confirms the good long-term outcomes of sialendoscopic interventions in patients with chronic sialadenitis of different etiologies and a high rate of gland preservation.
