Objectives: This study aimed to compare the effects of different intra-articular injections using a mixture of hyaluronic acid (HA) and platelet-rich plasma (PRP) versus hyaluronic acid and corticosteroid in the management of TMJ internal derangement with reduction. Materials and Methods: Sixty patients were randomly divided into two equal groups. Group I was injected with hyaluronic acid and PRP, while group II was injected with hyaluronic acid and corticosteroid. Pain intensity according to the visual analogue scale, maximum inter-incisal opening (MIO), lateral movement, and joint sound were measured pre-operatively and at 1 week, 1 month, and 6 months post-operatively. Results: MIO and lateral movements were improved in both groups, with a reduction in the number of patients suffering from clicking sounds along the follow-up periods with no significant difference between the studied groups. However, regarding pain, the group injected with HA and PRP achieved the best results after 6 months, while patients treated with HA and corticosteroids obtained the best results at the end of the 1st week. Conclusion: Hyaluronic acid and platelet-rich plasma mixture performed better than hyaluronic acid and corticosteroid in the treatment of TMJ internal derangement with reduction at the long-term follow-up regarding pain intensity.
