Abstract

Purpose: The study assessed the efficacy of orthopedic suture anchor as a modified suture anchor for disc repositioning in case of a closed lock of TMJ.

Patient and methods: Disc repositioning was undertaken via a mini preauricular approach. The disc was repositioned on the surface of the condyle and stabilized using an orthopedic suture anchor. Postoperatively functional outcomes were assessed in terms of reduction in pain, joint movement and absence of joint noise and clicking sounds. Postoperative MRI was used to assess the disc position and morphological changes in the disc and arthritic changes in the condyle at the end of six months.

Results: Patients were post surgically followed up at regular intervals of 1, 3 and 6 months. Patient experienced significant improvement in mouth opening with good functional outcomes and stable repositioning of disc as noticed By MRI at the end of six months.

Conclusions: We describe a modified technique of disc repositioning using an orthopedic suture anchor for more favorable disc position and joint function. However the long term functional sequel of the procedure and changes in the articular disc needs to be assessed.

Keywords: Disc repositioning; Internal derangement; Orthopedic suture anchor.
