Abstract
Aim: The aim of this study was to compare the efficacy of arthrocentesis with arthrocentesis plus steroid in the treatment of temporomandibular joint (TMJ) internal derangements. Methods: Nine males and 11 females aged 17-39 years were enrolled in the study. The patients were complaining of limited mouth opening and TMJ pain. Arthrocentesis was performed under aseptic conditions. All patients were clinically evaluated before the procedure, and 1 week and 6 months after the procedure. Intensity of TMJ pain and maximal mouth opening was recorded at each follow-up visit. Results: Both groups showed significant improvement in mouth opening and a reduction in pain scores in the postoperative period; however, the addition of steroid did not improve the overall outcome of the procedure. Conclusion: Arthrocentesis is a simple and safe procedure for patients with internal derangement of the TMJ with closed lock. However, the outcome was not improved by the addition of steroid.
