Abstract
Question: Is arthrocentesis with sodium hyaluronate more effective than arthrocentesis alone in people with temporomandibular joint derangements?
Objective To investigate the efficacy of arthrocentesis with and without injection of sodium hyaluronate (SH) into the upper joint space in the treatment of temporomandibular joint (TMJ) internal derangements.
Design Randomised non-blinded prospective trial.
Intervention Thirty-one people (five males and 26 females, age 14–53 years) who had TMJ problems in 41 joints were randomly divided into two treatment groups. One group received arthrocentesis alone, the other arthrocentesis plus intra-articular injection of SH. Both groups contained patients with disc displacement with reduction and with closed lock. Patients were evaluated before the procedure, on postoperative day 1 and then regularly for 24 months.
Outcome measures Intensity of TMJ pain, jaw function and clicking sounds in the TMJ were assessed using visual analogue scales (VAS). Maximal mouth opening and lateral jaw movements also were recorded at each follow-up visit.
Results Both techniques increased maximal mouth opening, lateral movements and function while reducing TMJ pain and noise. Maximal jaw opening increased at 24 months in both groups (see Table 1).
Conclusions Patients benefited from both techniques but arthrocentesis with injection of SH seemed to be superior to arthrocentesis alone. Jaw function improved and maximal mouth opening increased earlier and continued longer in arthrocentesis and SH group.
