[Temporomandibular ankylosis and progressive ossifying myositis. Review of the literature apropos of a case report].

A case of extraarticular temporomandibular ankylosis due to progressive ossifying myositis is reported. The local pathology appeared 13 years after the initial generalized symptomatic onset. CT scan helps to the diagnosis. Despite surgical therapy, the pathology reappears so we conclude to the unique efficiency of medical therapy: corticosteroids by pulse therapy. A review of the literature on the subject was made. A discussion ends the publication.
