A Randomized Controlled Trial of Superior and Inferior Temporomandibular Joint Space Injection with Hyaluronic Acid in Treatment of Anterior Disc Displacement Without Reduction

Superior and Inferior Temporomandibular Joint Space Injection with Hyaluronic Acid in Treatment of Anterior Disc Displacement Without Reduction

Article specifications

This clinical trial was published in 2009 in Journal of J Oral Maxillofac Surg. (IF 2012:1.333) by Chinese specialist. The purpose of the present study was to compare the outcome of inferior and superior joint space injection of sodium hyaluronate in patients with disc displacement without reduction of the temporomandibular joint (TMJ). One hundred twenty patients with disc displacement without reduction of TMJ
were randomized into 2 experimental groups. One group of patients received superior joint space injections of sodium hyaluronate and the other group was treated with inferior joint space injections. Patient’s TMJ status and clinical symptoms were evaluated at the 3 and 6-month follow-up appointments.

 

Results

This study showed that inferior joint space injection with sodium hyaluronate is a valid method of treating disc displacement without reduction of TMJ and a long-term study will be needed to assess the effect of inferior joint injection on the morphologic changes of the TMJ.
