OBJECTIVE: To investigate the relative contribution of various risk factors to the surgical outcome of adenotonsillectomy for obstructive sleep apnea syndrome in children. STUDY DESIGN: Children (n = 110; mean age, 6.4 +/- 3.9 years) underwent two polysomnographic evaluations before and after adenotonsillectomy. In addition, 22 control children were studied. History for allergy and family history of sleep-disordered breathing was taken before each polysomnographic evaluation. RESULTS: Significant changes in sleep stage percentages and sleep fragmentation were found in the postsurgery study compared with the presurgery study; 25% of the children had apnea/hypopnea index (AHI) 1 and <5, and 29% had AHI >/=5 in the postsurgery study. The frequency of subjects with AHI
