Efficacy of coblation assisted surgery in obstructive sleep apnea with obstruction at the retropalatal level

Abstract

Introduction: Obstructive sleep apnoea syndrome (OSAS) is a common sleep disorder caused by abnormalities in the pharynx and upper airway muscles. Uvulopalatopharyngoplasty (UPPP) is the commonly indicated surgical procedure for the management of OSA. Recent studies state that coblation assisted UPPP can improve the outcomes of OSA.
Aim : To study the efficacy of coblation assisted uvulopalatopharyngoplasty in Obstructive Sleep Apnea Syndrome with isolated obstruction at the retropalatal level.
Materials and Methods: This prospective before-after analysis was conducted in Government Kilpauk Medical College Hospital and Government Royapettah Hospital attached to Kilpauk Medical College from September 2016 to September 2017. After a thorough examination, patients with moderate and severe OSA with obstruction at the retropalatal level were selected for the study. Institutional ethical clearance was obtained and all patients signed the written informed consent form.
