Purpose: The aim of the present study was to evaluate the efficacy of arthrocentesis with and without sodium hyaluronate (SH) injection in the treatment of patients with temporomandibular joint (TMJ) internal derangement. Materials and Methods: The study consisted of 20 patients with chief complaints of limited mouth opening, TMJ pain, and jaw deviation. Patients with disc displacement with reduction and closed lock were randomly divided into two groups. In Group 1, only arthrocentesis was performed, and in Group 2, arthrocentesis plus intra-articular injection of SH was performed. Arthrocentesis was performed under aseptic conditions using normal saline. Clinical evaluation was done for maximum mouth opening (MMO), TMJ pain, and jaw deviation before the procedure and 1 week, 2 weeks, 1 month, and 3 months following arthrocentesis. Results: The mean visual analog scale (VAS) score change was statistically significant in Group 1 and Group 2 for within the group analysis. There was statistically significant difference in VAS score between Group 1 and Group 2 at all time intervals postoperatively. The increase in MMO from preoperative to 3 months postoperatively was statistically significant for within the group analysis. There was a reduction in mandibular deviation in both Group 1 and Group 2, but the difference was not statistically significant. There was no statistically significant difference in deviation between the two groups. Conclusion: Arthrocentesis with SH is superior to arthrocentesis alone in treating patients suffering with TMJ internal derangement, who are refractory to conservative treatment.
