Condylar ankylosis: Unilateral posttraumatic condylar pseudoankylosis

Sung-Gyu Hong , Sung-Joon Hong

Abstract

The ankylosis of temporomandibular joint occured by several causes directly developes TM joint disfunction, In cases with prolonged condylar ankylosis, especially at growing age the condylar ankylosis evokes malfunction of growth center area, and then develops the abnormal facial morphology and malocclusion. Therefore it must be cured. Almost authors have agreed to the necessity of surgical correction of the TMJ anlylosis. but they did not decide the one surgical method to get the best result. The Tx. method suggested by many authors are the using interposition after resection of condyle to remain a lever of 3rd class in Mn. kinetics, the autogenous condylar graft and the alloplastic condylar graft. Some authors have got the satisfied results only with the condylectomy of the involved TMJ. This study also operated only the detachment of fibrous adhesion on ankylosed condylar side and then established occlusion in the case with the unilateral TMJ ankylosis and fibrous joint adhesion and facial asymmetry evoked after the fracture of condylar head at early age. This study got a improved mouth opening and a stable postsurgical result after I year. Also, this study reviewed many author´s study about the chanracteristics, etiology, diagnosis and Tx. method for the ankylosis of TMJ.
