To determine if standardized intraoperative scoring of anatomic obstruction in children with obstructive sleep apnea correlates with the apnea‐hypopnea index (AHI) and lowest oxygen saturation on preprocedural polysomnogram (PSG). A secondary objective was to determine if age, presence of a syndrome, or previous adenotonsillectomy affect this correlation. Study Design Case series with chart review. Setting Two tertiary care children’s hospitals. Subjects Patients with a preprocedural PSG who underwent drug‐induced sleep endoscopy (DISE) over a 4‐year period. Methods All DISEs were graded in a systematic manner with the Chan‐Parikh (C‐P) scoring system. AHI and nadir oxygen saturations were extracted from preprocedural PSG. Data were analyzed with a multivariate linear regression model that controlled for age at time of sleep endoscopy, syndrome diagnosis, and previous adenotonsillectomy. Results A total of 127 children underwent PSG prior to DISE: 56 were syndromic, and 21 had a previous adenotonsillectomy. Mean AHI was 13.6 ± 19.6 (± SD), and mean oxygen nadir was 85.4% ± 9.4%. Mean C‐P score was 5.9 ± 2.7. DISE score positively correlated with preoperative AHI ( r = 0.36, P 〈 . 0001) and negatively correlated with oxygen nadir ( r = −0.26, P =. 004). The multivariate linear regression models estimated that for every 1‐point increase in C‐P score, there is a 2.6‐point increase in AHI (95% confidence interval: 1.4‐3.8, P 〈 . 001) and a 1.1% decrease in the lowest oxygen saturation (95% confidence interval: –1.7 to −0.6, P 〈 . 001). Conclusion The C‐P scoring system for pediatric DISE correlates with both AHI and lowest oxygen saturation on preprocedural PSG.
