Objective To explore the application effect of aesthetic tragal incision in temporomandibular joint disc repositioning surgery. Methods A total of 41 patients who underwent temporomandibular joint disc repositioning surgery at the First Afffliated Hospital of Xinjiang Medical University from January 2022 to December 2024 were selected, and they were divided into group A (19 patients, 27 sides) and group B (22 patients, 31 sides) according to different incisions used. Group A adopted traditional preauricular crutch-shaped incision, and group B adopted aesthetic tragal incision. The clinical symptoms, joint disc repositioning effect, Stony Brook Scar Evaluation Scale (SBSES) score, satisfaction and complications were compared between the two groups. Results The maximum mouth opening of the two groups at 6 months after surgery was higher than that before surgery, and the VAS score was lower than that before surgery (P<0.05). There were no statistically signiffcant differences in maximum mouth opening and VAS score between the two groups at 6 months after surgery (P>0.05). There was no statistically significant difference in joint disc repositioning effect between the two groups (P>0.05). The SBSES score and satisfaction score of group B were higher than those of group A (P<0.05). The incidence of complications in group B was 22.58%, compared with 37.04% in group A, the difference was not statistically signiffcant (P>0.05). Conclusion The application of aesthetic tragal incision in temporomandibular joint disc repositioning surgery can effectively improve the severity of postoperative scars and enhance patient satisfaction, without affectingthe joint disc repositioning effect and patient prognosis.
