Obesity and persisting sleep apnea after adenotonsillectomy in Greek children.

Background: The relative importance of obesity and adenotonsillar hypertrophy in the pathogenesis of obstructive sleep-disordered breathing (SDB) in childhood is unclear. Adenotonsillectomy (AT) for SDB is not always curative, and obese children are at increased risk for residual disease postoperatively.

Objective: The aim of this investigation was to assess the efficacy of AT as treatment for SDB in obese and nonobese children.
