Modified temporomandibular joint disc anchor: the technique and note

Purpose: To introduce an advanced anchor technique for internal derangement of temporomandibular joint.

Methods: Consecutive 177 patients (232 TMJs) diagnosed as ID, through clinical examinations and MRI, were treated with a newly modified anchor technique from July 2011 to March 2012. The technique is commonly proposed for TMJ ID. The advanced approach was to put an anchoring nail in middle of the inclined surface, just below the posterior oblique surface of the condyle and use two 3-0 Nylon sutures fixing disc to the anchoring nail. Both preoperative and postoperative MRIs were taken to judge the disc position. For patients with malocclusion or irregular dentition, reposition biting plate and orthodontic treatment were also involved.

Results: Among 232 joints of postoperative MRIs, 226 joints (172 cases) were excellent and 4 joints (4 cases) were good, only 2 joints (1 case) were poor which was needed a second open surgery. The total effectiveness was 99.14%.

Conclusion: This advanced procedure has provided successful results in the treatment of TMJ ID. The design was more reasonable. But further clinical evaluation is necessary.
