Drug-induced sleep endoscopy findings in surgically-naïve obese vs non-obese children

To determine if drug-induced sleep endoscopy (DISE) findings are different in obese versus non-obese pediatric patients with obstructive sleep apnea (OSA) or sleep-disordered breathing (SDB). Prospective, observational cohort study from June 2017 to June 2018 at a tertiary academic pediatric medical center that included surgically-naïve children ages 2–12 with diagnoses of OSA or sleep-disordered breathing. Subjects with a known diagnosis of craniofacial syndromes, genetic disorders, prior adenoidectomy or tonsillectomy, or chronic tonsillitis as the indication for surgery were excluded. Two groups were assessed for patterns of obstruction based on DISE videos at each anatomic airway level using a previously published DISE scoring system. The groups included obese subjects (BMI ≥ 95th percentile) and non-obese controls (BMI
