Effect of Multilevel Upper Airway Surgery vs Medical Management on the Apnea-Hypopnea Index and Patient-Reported Daytime Sleepiness Among Patients With Moderate or Severe Obstructive Sleep Apnea

In this RCT (n=102), surgery reduced number of apnoea/hypopnoea events (mean baseline-adjusted difference, −17.6 events/h;p < 0.001) and patient-reported sleepiness (mean baseline-adjusted between-grp difference in Epworth scale, −6.7, p < 0.001) vs medical management at 6 mths
