Are YouTube videos about skull bone anatomy useful for students?

The aim of this study was to evaluate the content, quality, and functionality of YouTube videos on the anatomy of skull bones and to measure their educational usefulness. In this cross-sectional study, the keywords "skull bones" and "skull anatomy" were searched in the YouTube search tab. Demographic data such as type, source, duration, upload date, and view rates of the videos were recorded. The quality and content of the videos were measured using the total content score (TCS), modified DISCERN scale, JAMA score, and Global Quality Scale (GQS). SPSS 26.0 software was used for statistical analysis. Twenty-five (34.7%) of the first 72 videos found by keyword searches were included in the study. According to the GQS criteria, six of them (24%) were considered useful and 19 (76%) not useful. There was a strong statistically significant correlation between the GQS and DISCERN scores (r = 0.813, p < 0.001). There were strong statistically significant positive correlations between TCS and GQS scores (r = 0.887, p < 0.001) and between TCS and modified DISCERN scores (r = 0.691, p < 0.001). Additionally, there was a moderately strong statistically significant positive correlation between GQS and JAMA scores (r = 0.507, p < 0.05). There were also moderately strong statistically significant correlations between JAMA score and DISCERN score (r = 0.521, p < 0.001), video length (r = 0.416, p < 0.05), number of comments (r = 0.457, p < 0.05), and number of "likes" (r = 0.608, p < 0.001). There was a moderately strong statistically significant positive correlation between TCS and JAMA scores (r = 0.431, p < 0.05). Most YouTube videos have insufficient information about skull bones to meet the expectations of medical and dental school curricula. Anatomists and institutions should be encouraged to prepare and present YouTube videos using assessment systems such as DISCERN, JAMA, GQS, and TCS, in line with current anatomy curricula.
