Objective <p>The current study aims to analyze the educational quality of septoplasty videos on YouTube and to investigate the Instructional Videos in Otorhinolaryngology by YO-IFOS grading system (IVORY-GS), the first otorhinolaryngologic video evaluation system based on the IVORY guidelines.</p> Methods <p>In March 2023, a YouTube search for the terms “septoplasty,” “closed septoplasty,” and “deviated nasal septum surgery” was performed. Videos of operations on patients and cadaver dissections were included. The IVORY-GS was adapted for septoplasty and used to evaluate the quality of videos in terms of ethical considerations, technical aspects, case presentation, surgical procedure, and organ-specific elements. Descriptive data on the videos were collected, including views, likes, video duration, and time since publication. Statistical tests were applied to identify correlations between the characteristics of the videos and the overall IVORY-GS score.</p> Results <p>A total of 105 septoplasty videos were included. While 40% showed a Cottle technique, 53% observed the Killian technique. The average overall IVORY-GS score for septoplasty videos was 25.3 (maximally 48.0). In only 10% of the videos was the training quality evaluated as moderate/high. In comparison to macroscopic videos and videos published within the past 50&#xa0;months, endoscopic videos received significantly higher overall scores (both <i>p</i> &lt; 0.01). There was a significant correlation between the overall IVORY-GS score and the number of likes (<i>p</i> = 0.02). A higher overall score was a significant predictor of the number of likes (<i>p</i> = 0.02).</p> Conclusion <p>The analysis shows that only a small proportion of the septoplasty videos available on YouTube are suitable for surgical education. The IVORY-GS is useful for evaluating the training quality of videos in otorhinolaryngology and could be helpful for creation of a dedicated online platform for high-quality ENT surgical videos.</p>
