[Arthroscopic sclerotherapy and suturing for disc displacement of the TMJ]

The generation of the scar using TMJ arthroscopic sclerotheray in retrodiscal tissue needs some weeks. As the sclerotherapy can't fix disc reposited at once, we designed some new methods of discal traction suture with posterior sclerotherapy and anterior release.

30 cases with 15 joints of disc displacement with reduction and 16 joints of disc displacement without reduction were treated with the above-mentioned techniques.

The mean follow-up period was 27 mon (range 6-39). According to the rang of interincisal distances during maximum active opening and painful level using a standard 100 mm visual analog scale, and, analyzing an eight-item jaw pain questionnaire and jaw function using 5 item jaw function questionnaire, the total success rate was 74.2% (23/31), the success rate of disc displacement with reduction was 93.3% (14/15), and the success rate of disc displacement without reduction was 56.4% (9/16).

TMJ arthroscopic disc traction suture with posterior sclerotherapy and anterior release is effective on disc displacement. Diagnosis, treatment and post-operative evaluation can be performed in the same arthroscopic procedure.
