Abstract Goals To perform a medical analysis of the contribution of sialendoscopy in the treatment of non-tumoral pathologies of the main salivary glands, in Reunion Island, a French overseas territory. Material and method A multicenter retrospective observational study was conducted for an 8-year period, before and after introduction of sialendoscopy (2011–2014 and 2015–2018), following STROBE guidelines. Objectives To compare populations treated before (period A) and after (period B) the introduction of sialendoscopy in terms of clinical characteristics, and analyze the characteristics of patients treated by sialendoscopy. Results Two hundred and sixty-five patients were included: 74 in 2011–2014 and 191 in 2015–2018; 139 had sialendoscopy. Populations A and B were comparable except for the proportion of parotids treated (9% vs. 31%, respectively; P  Conclusion Although follow-up ranged between 12 and 55 months (median, 30 months), sialendoscopy appeared to be a useful and reliable technique, with a role in therapeutic strategy for the management of non-tumoral salivary pathologies in Reunion Island.
