Adenotonsillectomy Outcomes in Treatment of Obstructive Sleep Apnea in Children: A Multicenter Retrospective Study

AT leads to significant improvements in indices of sleep-disordered breathing in children. However, residual disease is present in a large proportion of children after AT, particularly among older (>7 yr) or obese children. In addition, the presence of severe OSAS in nonobese children or of chronic asthma warrants post-AT nocturnal polysomnography, in view of the higher risk for residual OSAS.
