Patient-perceived outcome after sialendoscopy using the glasgow benefit inventory

Sialendoscopy is a technique for investigating and managing obstructive salivary disease that avoids risks associated with the more invasive sialoadenectomy and other open surgery techniques. To date, surgeon-based outcomes have been reported, but only one report of patient-oriented outcomes has appeared in the literature. The objective of this study was to review our experience after introducing sialendoscopy to New Zealand and report the patient-perceived benefit.

A prospective observational study of all sialendoscopic procedures performed in the only sialendoscopy-practicing center in New Zealand between June 2010 and June 2012.

Clinical and epidemiological data of all patients were recorded. Sialendoscopic findings, complications, and outcomes were noted. The Glasgow Benefit Inventory questionnaire was administered to the patients at their follow-up.

Fifty-four patients underwent a total of 66 sialendoscopic procedures, involving 44 parotid and 22 submandibular glands. There was a complete symptom resolution in 54 procedures (82%). Sialolith removal was successful in 67% of cases, with postsialendoscopy symptom resolution in 86% of sialolithiasis cases. Symptoms resolved in 81% of cases with ductal stenosis. The overall mean Glasgow Benefit Inventory score was +31, which compares very favorably with other otolaryngology procedures.

This study shows a substantial positive patient-perceived benefit of sialendoscopy for both sialolith- and stenosis-based pathology. The overall rate of symptom resolution is comparable to international literature.
