Sialendoscopy-assisted combined approach for parotid sialolithotomy: Our long-term experience.

Abstract

To assess the long-term outcome of sialendoscopy-assisted combined approach for parotid sialolithotomy with gland preservation. A retrospective study of patients treated with a combined sialendoscopic and open approach was conducted between 2011 and 2020. Demographic data of patients such as operative technique, stone size, stone location, complications, and symptom relief were collected. Patients were followed up via clinical examination and questionnaires. Seventy-four patients were included and underwent endoscopy-assisted combined operations for the removal of 98 parotid stones. Of the 98stones, 92(94%) stones were completely removed and 6(6%) were partially removed. At a mean follow-up of 47.1±35months, 65 of 74 patients (88%) achieved long-term success. Patients with stone incomplete removal were significantly more often to develop the recurrence of obstructive symptoms (p=0.000) There were no cases of facial nerve injury or fistula formation. Gland function was preserved in 73 of 74 patients (99%). The combined approach for parotid stones is a safe and gland-preserving alternative to parotidectomy. The techniques described here show high success rates and good long-term results, and they avoided the need for gland resection in >95% of cases.
