ObjectiveTo establish how assessment of adenoid size is correlated between drug-induced sleep endoscopy (DISE) with indirect mirror nasopharyngoscopy (IMN).Study DesignRetrospective chart review.SettingTertiary care academic hospital.MethodsOver a 6-year period, 154 pediatric patients underwent DISE for obstructive sleep apnea and had IMN. DISE videos were assessed by one reviewer, blinded to results of mirror exams. IMN findings were taken from operative notes recorded by one attending physician. Demographic data, co-morbidities, and sleep study results were also recorded.ResultsNinety-three (58.5%) males and 66 (41.5%) females were included. Mean age at DISE was 7.34 ± 3.99 years, with an average of 29 days after DISE until nasopharyngeal mirror examination. The mean initial adenoid size based on DISE assessment was 2.62 + 0.99, and on nasopharyngeal mirror assessment was 2.56 + 0.97. DISE and IMN assessment of adenoid size correlated well (Spearman's Rho = 0.82, P < 0.00001; Kendal tau = 0.764, P < 0.00001).ConclusionsDISE has proven to be an excellent tool to assess adenoid size prior to adenoidectomy in children with OSA.
