Comparison of the state of sleep in patients with sleep-disordered breathing before and after surgical treatment.
In 19 surgically treated patients with sleep-disordered breathing for whom electroencephalograms could be recorded before and after surgery, and in 10 patients who suffered from daytime lethargy as assessed using the Epworth Sleepiness Scale (ESS) score, correlations between the stages of sleep before surgery and the ESS score and apnea-hypopnea index (AHI) were evaluated, and changes in AHI and the stages of sleep after surgery were examined. Neither the preoperative severity of AHI nor the ESS score showed an association with the stages of sleep. The improvement in the quality of sleep tended to be greater as the percentage improvement in the ESS score increased.
