Salivary Gland Lithiasis Recurrence After Minimally‐Invasive Surgery: Incidence, Risk Factors and Prevention.

Objective: The aim of this study was to evaluate the recurrence rate of lithiasis following minimally invasive surgery to identify risk factors and mechanisms for recurrence of salivary gland lithiasis. Study Design: Retrospective case series. Methods: A retrospective study was conducted including all patients treated for salivary gland lithiasis by minimally invasive surgery, such as sialendoscopy, intracorporeal lithotripsy, extracorporeal lithotripsy, transoral approach, and combined approach in our Department. We analyzed the recurrence rate of salivary lithiasis, their topography and timeline. Result: Three hundred four patients were included in this study, the mean age was 49 years (range 12–90 years), and the mean duration of follow‐up was 19.8 months (range 0–66 months). Fifteen patients (5%) presented secondary lithiasis. In all but one case, recurrences involved the same gland as primary lithiasis, and most frequently the submandibular gland. Recurrences occurred from 3 to 46 months postoperatively. Fourteen patients, who presented recurrence, had been initially treated by transoral approach. Recurrent lithiasis were treated by transoral approach or submandibulectomy. Conclusion: Salivary gland lithiasis recurrence was rare after minimally invasive salivary gland surgery. This study reinforced the concept that salivary gland lithiasis should be considered as a duct pathology. Level of Evidence: 4 Laryngoscope, 131:794–799, 2021 [ABSTRACT FROM AUTHOR]
