Abstract

Objective: Conventional reference images of laryngeal pathologies may provide educational value for Otolaryngology-Head & Neck Surgery (OHNS) residents, but observing dynamic vocal fold function is critical for diagnosis. Our aim was to develop and validate a video atlas of laryngeal pathologies for resident education in OHNS.

Design: A multi-institution, prospective case-control study.

Setting/participants: Ten videos showing 10 representative laryngeal pathologies were verified by two laryngologists. Six videos per category with kappa>0.8 were included in the video database. A collection of the videos was shown to a group of OHNS residents in a quiz fashion to determine if senior trainees would score higher than junior trainees. Another group of residents in OHNS was recruited and randomized to control or intervention. The control group was shown a quiz of 10 laryngeal videos at baseline and 24 weeks later. The intervention group was shown quizzes at baseline and every 6 weeks, ending at 24 weeks. Free-text diagnoses were scored for accuracy. Descriptive statistics, two-tailed tests, and analysis of covariance were performed.

Results: Twenty-nine residents participated, with 14 (48.3%) randomized to control, and 15 (51.7%) to the intervention. The postgraduate year (PGY) level had a significant impact on diagnostic performance. PGY1 and 2 had a significantly lower score than PGY5 (P = 0.017 and P = 0.035, respectively). PGY3 and PGY4 scores were not statistically different from PGY5 scores. The mean score difference between groups decreases as the PGY level increases (mean difference between groups = 0.87, P = 0.153), but this was not significant.

Conclusions: The current study has created a validated collection of videos that are representative of common laryngeal pathologies and can be easily incorporated into resident video-based learning. Future directions include larger multi-site studies to further elucidate whether repeated viewing of this video atlas can improve OHNS resident laryngology knowledge.
