Are YouTube™ videos a reliable source of information about genioplasty?

Abstract

Background: The aim of this study was to evaluate the accuracy and quality of the information content of popular YouTube (TM) videos about genioplasty. Materials and methods: The keywords genioplasty, sliding genioplasty and genioplasty surgery were searched on YouTube (TM). It was filtered by the view count and the first 70 videos that met the inclusion criteria were evaluated. Each video was scored as ranging from 0 to 8 point and the videos were classified as bad, poor, good and excellent content. Kruskal-Wallis test was performed for statistical analysis. Intraobserver and inter-observer agreement were calculated Cohen's Kappa index. Results: The videos uploaded by the individuals were significantly higher total video duration (P < 0.001), number of comments (P = 0.048) and viewing rate (P = 0.036) than the others and the videos generally included their treatment journey. Most of the videos included bad information content. The number of likes (P = 0.037), dislikes (P = 0.037) and the interaction index (P = 0.026) of the bad information content videos were significantly higher than the others. The other parameters did not show a significant difference (P > 0.05). Conclusion: The results of this study would suggest that YouTube (TM) is not currently an appropriate source of information about genioplasty for the patients. (C) 2020 Elsevier Masson SAS.
