Management of Juvenile Temporo-mandibular Joint Ankylosis by Gap Arthoplasty

Abstract

Bony ankylosis of the temporomandibular joint (TMJ) in a male patient was not diagnosed until the patient reached his early teens, at which time the condition was treated with a costochondral graft. At the time of treatment, there was an expectation that further orthognathic surgery would be required to correct the skeletal deformity. However, with the release of the ankylosis and growth of the costochondral graft, a good functional and esthetic result was achieved without further surgery. It is important that family dentists be aware of the clinical signs and symptoms of TMJ ankylosis, to allow early diagnosis and treatment.

Temporomandibular Joint Ankylosis: Anesthetic Challenge

“…Temporomandibular joint (TMJ) ankylosis can be bony or fibrous, true (intraarticular) or false (extraarticular) [ 1 ]. Children who have TMJ ankylosis may develop mandibular retrognathism, which can lead to functional and esthetic deficiencies [ 2 ]. This can result in limited movement of the jaw and difficulty with activities, such as speaking, eating, and opening the mouth.…”

“…In addition, as the result of insufficient nutrition, the children's development remains behind their counterparts. [2][3][4] The most common cause of TMJ ankylosis is trauma or infection. The incidence of TMJ ankylosis due to trauma ranges from 26% to 75%.…”
