  • Sleep endoscopy as a diagnostic tool in pediatric obstructive sleep apnea INTERNATIONAL JOURNAL OF PEDIATRIC OTORHINOLARYNGOLOGY Truong, M. T., Woo, V. G., Koltai, P. J. 2012; 76 (5): 722-727

    Abstract:

    Ten to twenty percent of children have persistent obstructive sleep apnea (OSA) after adenotonsillectomy (T&A). We hypothesize that sleep endoscopy, a flexible fiberoptic examination of the pharynx under anesthesia, is an effective tool for identifying sites of persistent obstruction.In this retrospective cohort study, we reviewed records of children who had symptoms consistent with OSA and a positive polysomnogram (PSG) who underwent sleep endoscopy followed by sleep endoscopy directed surgery. Data collection included age, BMI and co-morbidities. Apnea-hypopnea index (AHI) was compared to pre and post surgery for each child using a paired t-test.Of the 80 children who underwent sleep endoscopy followed by directed surgery, 65% were male, mean age was 6 years (SD 3.75 years), average BMI was 19 (SD 0.43 years) and 28% had co-morbidities. For the 51% of patients who had persistent OSA after T&A, the mean AHI after sleep endoscopy directed surgery was significantly lower then before surgery (7.9 vs. 15.7, p<.01). For the 49% of patients who had never undergone surgery for OSA, or who were surgically naïve, and underwent sleep endoscopy directed surgery, the mean AHI was significantly lower then before surgery (8.0 vs. 13.8, p<.01).Sleep endoscopy is a consistently reliable tool for identifying the sites of obstruction in both surgically naive children and those with persistent OSA after T&A.
