OSAS is characterized by snoring, recurrent partial (hypopneas) or complete obstruction (apneas) of the upper airway, frequently associated with intermittent oxyhaemoglobin desaturations, sleep disruption and fragmentation. The gold standard test for diagnosing obstructive sleep apnea is a polysomnogram (PSG). Specifically, OSAS affects 1-4% of healthy children who are typically 2-8 years of age6, coinciding with adenotonsillar hypertrophy, the commonest cause of OSAS in children. Usual treatment for OSAS in children with adenotonsillar hypertrophy is an adenotonsillectomy (AT). However, there is clear evidence that not only is there a high prevalence of obstructive sleep apnea in obese children, but further, the AT is not successful for resolution of OSAS. This is, in part due to the fact that adenotonsillar hypertrophy is not the single most significant risk factor for OSAS in the obese population.
