The Effect of Adenotonsillectomy on Sleep Efficiency in Pediatric Patients

Objectives: To evaluate the impact of adenotonsillectomy (T&A) on sleep efficiency (SE) characteristics, a marker of sleep quality with implications for behavior and cognition in children with obstructive sleep apnea (OSA). Methods: We analyzed 139 children who underwent full-night polysomnography (PSG) before and after T&A between January 2021 and September 2023. Patients were stratified into three SE severity groups: normal (greater than or equal to 85%), mild-moderate (70%-84%), and severe (less than 70%). Results: < 0.001), with high individual variability. Conclusions: T&A improves SE and resolves OSA for many pediatric patients. However, a subset experiences worsening SE, particularly those with comorbidities like DS. These findings highlight the importance of individualized postoperative care and the need for further research into predictors of T&A outcomes in pediatric OSA. Level of Evidence: 4.
