The upper airway was examined under spontaneous breathing and the site (s) of upper airway obstruction or hypotonia were documented. Treatment decisions where based upon polysomnographic data and findings during DISE.Results: Nineteen children age 5.2 ({\textpm}3.6) years, BMI 15.8 ({\textpm} 2.3) kg/m2, obstructive apnea/hypopnea index (OAHI) 21.6/r ({\textpm} 27.8)/hr were included. Upper airway obstruction at the level of adenoids and tonsils was found in 15, these children were treated with adenotonsillectomy. Adenotomy was performed in 1 child with obstruction limted to the adenoidregion. Two children were treated with CPAP because of tonguebase collapse (n=1) or global hypotonia (n=1). One child with hypotonia and collapse of the epiglottis received orthodontic treatment. Postoperative polysomnographic data are presently available for 8 of those treated with adenotonsillectomy and all had an OAHI \< 2/hr (5.9 months post surgery).Conclusions: This pilot study shows that drug-induced sleependoscopy is feasible in OSA children and DISE-directed treatment may improve therapeutic (surgical) outcomes.}, issn = {0903-1936}, URL = {https://erj.ersjournals.com/content/42/Suppl_57/P4673}, eprint = {https://erj.ersjournals.com/content/42/Suppl_57/P4673.full.pdf}, journal = {European Respiratory Journal} }
