Abstract
Lip repositioning surgery is a minimally invasive procedure used in the treatment of gummy smile. With the increasing demand for aesthetic dental procedures, platforms like YouTube™ have become popular sources for visual health information. This study aimed to evaluate the quality, reliability, and educational value of YouTube™ videos related to lip repositioning surgery and to identify factors influencing video quality. This research was conducted on YouTube™ using the term "lip repositioning" on February 20, 2025. The first 150 videos sorted by relevance were screened. According to the inclusion criteria, 53 videos were recorded. Data such as video duration, upload source, view count, comments, likes/dislikes, and country of origin were recorded. Viewer engagement was analyzed through interaction index and viewing rate. Content was evaluated using the Video Content Quality (VCQ) score, Global Quality Scale (GQS) and DISCERN tool. Statistical analyses were performed with a significance level of P < 0.05. Most videos were uploaded by dentists (64.2%), and 71.7% were educational. The mean VCQ score was 9.98 ± 3.95, indicating low-to-moderate content quality. Videos uploaded by professionals had higher quality scores (p < 0.001), while 56.6% were of poor content quality. Although YouTube™ is a widely used source for health information, videos on lip repositioning surgery lack sufficient educational value and reliability. Professional content creation should be encouraged.
