ABSTRACT
OBJECTIVE:
While the Benjamin-Inglis classification system is widely used to categorize laryngeal clefts, it does not clearly differentiate a type 1 cleft from normal anatomy, and there is no widely accepted or validated protocol for systematically evaluating interarytenoid mucosal height. We sought to propose the interarytenoid assessment protocol as a method to standardize the description of the interarytenoid anatomy and to test its reliability. STUDYDESIGN:
Retrospective review of endoscopic videos.SETTING:
Pediatric academic center. SUBJECTS ANDMETHODS:
The interarytenoid assessment protocol comprises 4 steps for evaluation of the interarytenoid region relative to known anatomic landmarks in the supraglottis, glottis, and subglottis. Thirty consecutively selected videos of the protocol were reviewed by 4 otolaryngologists. The raters were blinded to identifying information, and the video order was randomized for each review. We assessed protocol completion times and calculated Cohen's linear-weighted κ coefficient between blinded expert raters and with the operating surgeon to evaluate interrater/intrarater reliability.RESULTS:
Median age was 4.9 years (59 months; range, 1 month to 20 years). Median completion time was 144 seconds. Interrater and intrarater reliability showed substantial agreement (interrater κ = 0.71 [95% confidence interval (CI), 0.55-0.87]; intrarater mean κ = 0.70 [95% CI, 0.59-0.92/rater 1, 0.47-0.85/rater 2]; P < .001). Comparing raters to the operating surgeon demonstrated substantial agreement (mean κ = 0.62; 95% CI, 0.31-0.79/rater 1, 0.48-0.89/rater 2; P < .001).CONCLUSION:
The interarytenoid assessment protocol appears reliable in describing interarytenoid anatomy. Rapid completion times and substantial interrater/intrarater reliability were demonstrated. Incorporation of this protocol may provide important steps toward improved standardization in the anatomic description of the interarytenoid region in pediatric dysphagia.Palavras-chave
