Abstract

ObjectivesTo determine the efficacy of adenotonsillectomy (T&A) in the treatment of pediatric sleep-disordered breathing, and to determine the natural history in untreated children. MethodsThe charts of children aged 1–12 who underwent polysomnography (PSG) between 1/2006 and 6/2009 were reviewed to identify children with positive studies. Children not treated by T&A were recruited and matched by age, time since initial PSG, and apnea-hypopnea index (AHI) to children who underwent T&A. All participants were evaluated by a clinical assessment score (CAS-15), follow-up PSG, and the Child Behavior Checklist (CBCL). ResultsSixteen matched pairs completed the study. Ten (63%) T&A patients were overweight or obese compared with 14 (88%) untreated patients. There was a greater median improvement in AHI in the surgical group compared to the nonsurgical group (10.3 vs. 6.5, p=0.044). Although the T&A children were more likely to have a follow-up AHI<5 (81% vs. 69%) and <1 (44% vs. 25%), these results were not significant. The T&A group had significantly lower mean (SD) scores on the CAS-15 [8.9(6.1) vs. 29.4(16.2), p<0.001] and the CBCL total problem score [43.9(8.7) vs. 58.9(13.0), p<0.001]. Younger age at presentation (rho=−0.76, p<0.001), initial AHI (0.87, p<0.001), and initial AI (0.63, p=0.05) were correlated with change in AHI among T&A subjects. ConclusionsT&A was more effective in reducing AHI than no surgery. Median AHI improved in the nonsurgical group, and 4/16 (25%) untreated patients were cured (AHI<1).
