Conclusion
The sleep problem of the majority of the children (51.3%) in this study was OSAS; however, only 7.4% of the total pediatric patients in the study underwent surgery for OSAS, even though some of the children with OSAS underwent surgery without undergoing PSG. We thus suggest that children with sleep problems should all undergo PSG studies, as PSG could help to detect significant sleep-related problems, and the application of PSG results is useful for making therapeutic decisions regarding children.
