Abstract
The aim of this study was to evaluate the quality and the educational content of YouTube videos showing parotidectomy. We searched for videos displaying parotidectomy on YouTube. To rate parotidectomy videos, we introduced the "Instructional Videos in Otorhinolaryngology by YO-IFOS (IVORY)-grading-system (GS)" derived from the IVORY Guidelines, which pose established consensus recommendations for the production of educational surgical videos in otolaryngology. The videos were rated using the IVORY-GS, and the total score was tested for statistical association with views, likes, likes/dislikes-ratio, age, and length of the videos for validation of the IVORY-GS. Overall, 50 parotidectomy videos were identified. Sixty-eight (68%) of the videos showed a superficial parotidectomy. The mean IVORY-GS total score was 24.9 (out of a maximum of 44 points). Video education quality was rated as moderate in 22% and high in 4%. There was a statistically significant correlation between the total score and the number of views (p= 0.03), the total score and the number of likes (p< 0.01), and the total score and the likes/dislikes ratio (p< 0.01). A higher total score was a significant predictor of more likes (p= 0.01) and a higher likes/dislikes ratio (p< 0.01). Our modification of the IVORY Guidelines is otolaryngology-specific, suitable, and recommended to evaluate parotidectomy videos. To date, most videos are of poor educational quality. Future efforts in otolaryngology surgical video education could focus on the establishment of an online video platform. NA Laryngoscope, 133:2631-2637, 2023.
