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

BACKGROUND

The aim of this study was to evaluate the accuracy and quality of the information content of popular YouTube™ videos about genioplasty.

MATERIALS AND METHODS

The keywords "genioplasty, sliding genioplasty and genioplasty surgery" were searched on YouTube™. 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. Intra-observer 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™ is not currently an appropriate source of information about genioplasty for the patients.
