Abstract
This was a retrospective study of sleep structures of seven pediatric patients diagnosed with obstructive sleep apnea syndrome based on the diagnostic criteria of the International Classification of Sleep Disorders. All patients underwent pre-and post-operative polysomnography and sleep stages were scored based on the Rechtschaffen and Kales classification. We identified significant polysomnographic changes in the sleep structures in children with obstructive sleep apnea syndrome after adenotonsillectomy. Both sleep stage 1 and arousals at night decreased significantly. Changes in slow wave stages were not statistically significant. Further research is needed to evaluate whether these changes might affect the post-operative mental and physical health.
