A Content Analysis of YouTube Videos on Facial Palsy in South Korea

Abstract

Background and Objectives YouTube has become a major source of health information,raising concerns regarding the accuracy of medical content. Facial nerve paralysis is a clinically significant condition with substantial functional, social, emotional, and economic impact. However, only limited studies have evaluated the quality of YouTube videos addressingfacial palsy. This study aimed to review video content and assess the quality of informationrelated to facial palsy on YouTube. Subjects and Method A YouTube search was performed using five Korean keywords: “안면신경마비,” “벨마비,” “람세이헌트,” “얼굴마비,” and “구안와사.” The top 100 Korean-language videos were screened using a newly created account. Videos unrelated to facial palsywere excluded. Content creators were categorized by professional background. Video qualitywas assessed using the Patient Education Materials Assessment Tool for Audiovisual Materials and a modified DISCERN score. Results Among the 100 included videos, 9 were produced by otolaryngologists, 44 by traditional Korean medicine doctors, 27 by other medical professionals, and 20 by lay persons. Bell’s palsy was the most commonly discussed condition, whereas Ramsay Hunt syndrome,central facial palsy, and traumatic facial paralysis were less frequently addressed. Otolaryngologists’ videos covered verified treatments such as corticosteroids, antiviral drugs, and protective agents for the eyes. Otolaryngologists’ videos showed significantly higher understandability and quality of information compared to others. Conclusion YouTube videos on facial palsy frequently contain low-quality or unverified information, which may negatively influence patients. The findings in this study highlight theimportance of specialist involvement in providing accurate and reliable medical information.
