To what extent is oral and maxillofacial surgery educational content posted on Instagram?

Hashtags on Instagram help users globally search for posts to their liking. This study aimed to determine who posts the most popular oral and maxillofacial surgery (OMS) hashtags on Instagram and to evaluate the impact of educational content. The posts were analyzed for the type of post and differences between content creators when posting OMS-related content. This cross-sectional study evaluated OMS content categorized by 36 hashtags. The top 9 posts with each hashtag were evaluated based on the type of content creator, if it was a video or picture, and if it was educational or for marketing purposes. 6 million posts existed among 36 hashtags. Regarding the categories of person/organization posting the content (US or non-US oral and maxillofacial surgeon, residency program, patient, and 'other'), the top posts (N = 295) were posted by 'other' and the least by 'residency program'. Among the posts by non-US oral and maxillofacial surgeons, there was 3.8-fold more marketing content, while among the posts by US oral and maxillofacial surgeons, there was 2-fold more educational content. Educational posts achieved the highest engagement in terms of 'likes'. This study highlights how oral and maxillofacial surgeons can educate the general population and expand their reach.
