Daytime sleepiness, a common complaint of people with obstructive sleep apnoea, improves greatly after surgery for the disorder, according to a new study.
Before their surgery, all of the study participants reported being very sleepy during the day. After surgery, however, ratings on standardised scales revealed that daytime sleepiness was greatly reduced in 38 of them. In addition, the participants experienced, on average, a 50% reduction in nighttime sleep interruptions, the study reported.
"This study validates what patients have told us regarding their improved alertness after surgery," said Dr Kathleen L. Yaremchuk, a study co-author who chairs the department of otolaryngology-head and neck surgery.
