Ankylosis Of The Temporomandibular Joint (Tmj)

Ankylosis of the TMJ is a stiffening or bony deformity of the joint.

Ankylosis of the temporomandibular joint (TMJ) is mostly due to a trauma or an infection, but can also be congenital or the result of rheumatoid arthritis (RA) his (Rheumatoid arthritis (RA)). There occurs a chronic, painless limitation of movement. If ankylosis leads to a standstill of the condylar growth, a facial asymmetry is frequently (hypoplasia of the condyle, condylar hyperplasia of the mandible). Intra-articular (real) ankylosing must be distinguished from the extra-articular (false) ankylosis that can be caused by an enlargement of the coronoid, a depressed fracture of the zygomatic arch or postoperative scarring, radiation or infection. In most cases, the real ankylosing radiographs of the joint show a loss of normal bone architecture.

In most cases, the real ankylosing radiographs of the joint show a loss of normal bone architecture. The treatment may consist of a condylectomy when the ankylosis is located intra-articularly, or ostectomy a portion of the Ramus when the coronoid process and the zygomatic arch are also affected. Mouth exercises must be done over months and years in order to get the result of the surgical correction; However, a forced opening of the jaw without surgery is generally ineffective because of the bony deformity.
