Purpose Drug-induced sleep endoscopy (DISE) is useful in children with obstructive sleep apnea (OSA) that persists after adenotonsillectomy (AT), but its utility in surgically naive children is unclear. We report polysomnography outcomes of surgically naive children who underwent DISE-directed intervention because they were considered high risk for persistent OSA after adenotonsillectomy. Methods This study is a case series of 62 surgically naive children with OSA who were considered high risk for persistence after AT and underwent DISE-directed intervention with pre- and postoperative polysomnography between 2012 and 2016. Analysis was performed with the pairedttest. Results Children were on average 5.9 (+/- 5.5, 0.2-18.6) years old at the time of surgery, 68% male, 18% obese, and 60% white. Thirty-eight percent had a syndromic diagnosis: 19% trisomy 21, 11% hypotonic neuromuscular disorder, and 8% craniofacial condition. The remaining 62% were non-syndromic but underwent DISE because they had at least one risk factor for OSA persistence after AT (age > 7 years, black race, 1+ tonsils, obesity, and/or severe OSA). Forty-two percent underwent AT, while 58% underwent treatment other than AT, including 18% who had multilevel surgery. Children improved significantly in 4 out of 5 polysomnography parameters tested, including obstructive apnea-hypopnea index (oAHI; 22.2 to 7.2,p < 0.01) and oxygen nadir (82 to 87,p < 0.01). Thirty-eight (61%) had a postoperative oAHI < 5; 16 (21%) had a postoperative oAHI < 2. Conclusion DISE resulted in intervention other than AT in 58% of surgically naive children at high risk for persistent OSA after AT. DISE-directed intervention resulted in significant mean improvement in postoperative OSA.
