Brief summary: Discopexy is a surgical procedure aimed at stabilizing the articular disc within the temporomandibular joint (TMJ) in patients experiencing TMJ disorders (TMD). The TMJ is a complex joint responsible for jaw movement, and its proper function relies on the alignment and stability of the articular disc, a fibrocartilaginous structure that cushions the joint. In cases of disc displacement or dysfunction, patients may experience pain, clicking, limited jaw movement, and other symptoms.

Detailed description: Discopexy involves repositioning and securing the displaced disc to its anatomical position, often using sutures or anchors, to restore normal joint mechanics and alleviate symptoms. This procedure is typically considered when conservative treatments, such as physical therapy or splints, have failed to provide relief. Discopexy aims to improve joint function, reduce pain, and prevent further degenerative changes in the TMJ. The aim of the present study is to compare between new surgical techniques of discopexy of TMJ disc either to external ear cartilage or to temporal fascia.
