Arthroscopic Disc Suturing and Repositioning Technique for Treating Anteriorly Displaced Disc in Temporomandibular Joint Disorders: A Posterior Anchorage Technique

Abstract

Several treatment modalities have been reported for patients with arthrogenous temporomandibular disorders. The most common temporomandibular disorder is internal derangement, usually accompanied by displacement of the articular disc. Most often anteriorly and medially displaced, patients may develop clicking, impaired jaw function, and pain. Articular disc repositioning has been described as an effective method to eliminate interference during mandibular translation, improving mandibular range of motion, and eliminating pain.

In this article, we present a new, simple, and reproducible technique without requiring specific instruments for repositioning and suturing the articular disc with posterior anchorage fixed to the tragus cartilage. It has the advantages of a better anteroposterior vector of traction force, without adverse effects as lateralization of the articular disc and skin depression, commonly presented in other techniques.
