Accuracy of Diagnosis of Benign Vocal Fold Lesions among Ear, Nose, and Throat Residents

Abstract

Introduction Benign vocal fold lesions (BVFLs) disrupt the superficial lamina propria, impacting vocal fold pliability. Investigating the diagnostic competency of ear, nose, and throat (ENT) residents in identifying BVFLs, we hypothesize that factors such as residency year, subspecialty focus, and training center influence diagnostic accuracy. Objectives To assess the accuracy of diagnosis of BVFLs among ENT residents and to correlate diagnostic accuracy with the year of residency. Methods An observational cross-sectional study included all ENT residents in Saudi Arabia. It was performed in August and September 2021 using a self-administered online questionnaire that assessed demographic variables and included three images with open-ended questions on diagnosing vocal fold lesions. Results A total of 61 ENT residents (62.3% male) were included in this study. The images of vocal fold cyst, vocal fold polyp, and vocal fold nodule were correctly diagnosed by 60.7%, 88.5%, and 91.8% of residents, respectively. There was a correlation between the year of residency and the accuracy of diagnosing a vocal fold cyst (p = 0.029). Residents interested in laryngology correctly diagnosed all three lesions more frequently than other residents. Conclusion The ability of residents to diagnose vocal fold cysts was moderate. In particular, the senior residents were able to diagnose polyps and nodules with excellent accuracy.
