Long- Term Outcomes in Obstructive Salivary Gland Disease due to Calculus after Sialendoscopy

Abstract

Background: The introduction of sialendoscopy has brought about a paradigm shift in salivary calculi management.
Objectives: To assess the long-term outcomes of sialendoscopy in obstructive salivary gland disease due to calculi.
Methods: This was a prospective observational study conducted among 65 patients of sialolithiasis who underwent interventional sialendoscopy for the same. Subjective assessments of salivary gland function were done before and after the procedure during pre- operative, and at first, sixth and twelfth month post- operative visits. The assessment was done by Chronic Obstructive Sialadenitis Symptoms(COSS) Questionnaire.
Results: Interventional sialendoscopy for sialolithiasis showed statistically significant improvement in COSS scores during all stages of evaluation.
Conclusions: Long-term evaluation of patients treated by interventional sialendoscopy showed good outcomes for sialolithiasis which were maintained at the end of one year after procedure. The positive outcome stresses the need for salivary gland preservation in sialolithiasis with a need for more centres practising sialendoscopy.
