The study aimed to evaluate the efficacy of disc release, fixation, and chitosan injection in treating TMJ-OA. It was found that this treatment had a significant effect on improving pain and maximum comfortable mouth opening. Results showed that among the 32 patients, 30 were satisfied with the treatment and two were unsatisfied.
Objective: Temporomandibular joint osteoarthritis (TMJ-OA) is common in clinic. The purpose of this study was to evaluate the efficacy of disc release, fixation and chitosan injection in the treatment of TMJ-OA. Methods: From March 2021 to March 2022, 32 patients who underwent the unilateral reduction and fixation of temporomandibular joint disc release were retrospectively studied. All patients were diagnosed with TMJ-OA and were treated with chitosan injection. This group of patients was analyzed by the visual analog scale (VAS) for pain and improvement of maximum comfortable mouth opening before treatment and 6 months after treatment. A paired t-test was used to evaluate the treatment effect, and p < 0.05 indicated that the difference was statistically significant. Results: All 32 patients were successfully treated by surgery and chitosan injection in the second week after operation. The duration of disease in this group ranged from 1 to 10 months, with an average of 5.7 months. After 6 months of follow up, 30 patients were satisfied with the treatment and two were unsatisfied. The difference in the treatment effect was found to be statistically significant (p < 0.05). Conclusions: Temporomandibular joint disc release and fixation combined with chitosan injection is effective in the treatment of TMJ-OA.
