Abstract
OBJECTIVES/HYPOTHESIS: 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. STUDY DESIGN: A prospective observational study of all sialendoscopic procedures performed in the only sialendoscopy-practicing center in New Zealand between June 2010 and June 2012. METHODS: 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. RESULTS: 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. CONCLUSIONS: 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. LEVEL OF EVIDENCE: 4.
