The Effect of Upper Airway Surgery on Sleep Quality and Obstructive Sleep Apnea

Objectives:Obstructive sleep apnea (OSA) is a common sleep disorder due primarily to upper airway obstruction. Certain ethnic groups, particularly Chinese, are more susceptible to a severe degree of OSA irrespective of body weight due in part to inherent narrow upper airway anatomy. In this study, we investigated the treatment outcome of combined upper airway surgeries: septoplasty (SP), turbinate reduction (TR), tonsillectomy, and uvulopalatoplasty (UVPP) on OSA in this ethnic group who have clinical identifiable upper airway anatomical obstruction and are unable to tolerate continuous positive airway pressure (CPAP) treatment.Methods:A retrospective study to analyze the effect of either: (1) SP and TR (inferior turbinectomy) only or (2) in combination with UVPP (partial uvulectomy and lateralization of palatal pillars) and standard tonsillectomy, on Chinese patients diagnosed with OSA. Outcome measures were obtained from pre- and postoperative polysomnographs (PSG) where sleep parameters, AHI, and oxyge...
