Abstract
Management of Temporomandibudar Joint Ankylosis with Costo-Chondral Graft Application: Case Report and Review of Literature
Highlights
The term ankylosis of temporomandibular joint (TMJ) is derived from the Greek word meaning stiffening of a joint due to disease process and referred to describe a permanent movement disfunction of the mandible caused by the fusion of joint surfaces by bone, fibrous or mixed tissue, bilateral or unilateral [1,2,3]
Extra-articular ankylosis may be due to the synostosis of the jaws after inadequate surgical treatment of the condylary area, development of fibrous tissue in the muscle masses which surrounding jaw, as well as other causes that create mechanical barriers to the movement of the mandible and due to region's sizable neoplasms [2,3]
The causes that lead to a true TMJ ankylosis may be congenital or acquired [4,5]
Summary
The term ankylosis of temporomandibular joint (TMJ) is derived from the Greek word meaning stiffening of a joint due to disease process and referred to describe a permanent movement disfunction of the mandible caused by the fusion of joint surfaces by bone, fibrous or mixed tissue, bilateral or unilateral [1,2,3]. Acquired etiologic factors include lesions, trauma and mainly intra-articular fractures of the condyle, local and systemic inflammatory conditions, neoplasms, TMJ infection and arthritis that lead to the synostosis of the TMJ (infectious or chronic inflammatory arthritis and mainly ankylotic spondylo-arthritis, rheumatoid arthritis, fibrosis and coronoid process hyperplasia). Reconstruction of the TMJ with autogenous element represents one of the most intriguing and challenging operations in all of the bone grafting [6,8] Purpose of this case report is to present the surgical management of a unilateral TMJ ankylosis and recent literature review. Resection of the newly formed bone mass, replacement of the condyle with the use of costo-chondral graft and replacement of the articular disc with the temporal fascia. Radiological examinations showed that the ankylosis was in the right TMJ due to the development of bone between the condyle and the articular fossa including anterior and posterior articular tubercle (Figure 2). Ten years after the surgical treatment and rehabilitation of the dental arches, the patient showed no recurrence and the postoperative result was maintained stable
