Abstract: Objective: To evaluate the efficacy of sodium hyaluronateacid(SH) injection combined with stabilizationsplint for the treatment of anterior disc displacement without reduction. Methods: Forty patients with temporomandibular joint anterior disc displacement without reduction were randomly divided into the experimental group and the control group. The experimental group wasinjected withSH in the articular cavity combined with stabilizationsplint, and the control group was only injected with SH in the articular cavity. Comparative analysis was performed before, 3 months, and 6 months after treatment in patients withFricton dysfunction index, pain index(VAS) and maximal mouth opening. Results: After treatment, temporomandibular dysfunction,arthralgia and mouth openingof patients in the two groups weresignificantly improved(P<0.05). No significant difference ofthe mouth opening was found between two groups (P>0.05). The VAS,CMI and DI of the experimental group decreased significantly than those of the control group (P<0.05). Conclusion: Intraarticular injection of SH combined with stabilizationsplint for the treatment of anterior disc displacement without reduction is betterthan the simple articular cavity injection of SH.
