Introduction: Temporomandibular joint osteoarthritis (TMJ OA) is a degenerative disease characterized by deterioration of articular tissue with concomitant osseous changes in the condyle and/or articular eminence, joint positive for TMJ noise with jaw movement or function, crepitus detected on palpation on opening, closing, right/left lateral, or protrusive movement. Hyaluronic acid (HA) is a polysaccharide of the family of glycosaminoglycans. HA has been shown to improve and restore normal lubrication in joint, provide nutrition to the avascular articulating disc, and stabilize the joint. Materials and Methods: Twenty patients with OA of TMJ with age limit between 18 and 60 years of age were enrolled in this study. Patients were randomly divided into two groups, in which one group received arthrocentesis only, and another group received arthrocentesis plus intra-articular injection of sodium HA (0.5 ml) in superior joint space in a cycle of 5 weekly arthrocentesis (one per week). Patients were followed at regular interval of 1st day, 5th day, 7th day, 4 weeks, 6 weeks, and 12 weeks. Assessment of clinical outcome was done in terms of reduction in pain (visual analog scale score), maximum mouth opening (MMO) in millimeters, painful/pain-free lateral or protrusive jaw movement, and clicking/crepitus in joint. Results: Significant reduction in pain was observed in both the groups. MMO, lateral and protrusive movements improved significantly in both groups; however, arthrocentesis with sodium HA was superior to arthrocentesis alone. Conclusion: Combination of arthrocentesis with HA injection showed much better outcome than arthrocentesis alone.
