Abstract
OBJECTIVES: To compare the efficacy and safety of transoral robotic surgery (TORS) with endoscope-guided coblation tongue base resection.
DESIGN: Retrospective case-control study.
SETTING: University-based tertiary care medical center.
PARTICIPANTS: OSA patients who underwent endoscope-guided tongue base coblation resection or TORS in combination with lateral pharyngoplasty at a single institution in South Korea between April 2013 and December 2016 were investigated. Forty-five patients who had moderate to severe OSA with tongue base collapse and a minimum follow-up period of 6 months with postoperative polysomnography (PSG) were enrolled in this study.
MAIN OUTCOME MEASURES: All patients underwent pre- and postoperative (at least 4 months after surgery) overnight PSG. Available information on results of the PSG, Epworth Sleepiness Scale, and complications of the TORS and coblation groups were compared.
RESULTS: Postoperative PSG studies showed improved sleep quality for most patients. The mean postoperative apnea-hypopnea index (AHI) was reduced significantly from 45.0 to 17.0 events/h (p < 0.0001) in the TORS group and from 45.6 to 16.2 events/h (p < 0.0001) in the coblation group. The mean rates of improvement (AHI reduction > 50%) were 75.0% in TORS patients and 62.1% in coblation patients; the difference was not significant. Less frequent postoperative morbidity, including bleeding, taste dysfunction, and foreign body sensation, were recorded in TORS patients.
CONCLUSIONS: Both the coblation and TORS groups showed similar surgical outcomes, TORS achieved PSG results non-inferior to and complication rates comparable to coblation. This article is protected by copyright. All rights reserved.
