OBJECTIVES: To correlate polysomnographic findings with clinical history of apnea, the degree of obstruction caused by tonsillar hypertrophy, and to age group. STUDY DESIGN AND SETTING: 267 children with a clinical diagnosis of obstructive sleep apnea (OSAS) were evaluated. Patients were divided into preschool- and school-age categories, and subdivided in 3 additional groups, according to tonsillar hypertrophy. Polysomnographic findings were compared within groups. RESULTS: 34% of children had history of OSAS and normal polysomnographic findings. Tonsillar hypertrophy was correlated to more severe apnea among preschool-age children, but not among school-age children. Among children with tonsillar hypertrophy, more severe apnea was observed in preschool-age children than in school-age children. CONCLUSIONS: There is little correlation between polysomnographic and clinical findings in children with OSAS. SIGNIFICANCE: Adenotonsillar hypertrophy leads to more severe polysomnographic patterns in preschool-age children. More severe apnea is observed in younger children with adenotonsillar hypertrophy than in older ones.
