CORRECTION OF BILATERAL BONY ANKYLOSIS OF THE TEMPOROMANDIBULAR JOINT ASSOCIATED WITH MICROGNATHIA

This is a case report of the bilateral bony ankylosis of temporomandibular joint associated with micrognathia, which was corrected by arthroplasty with silicone rubber implant in left side, condylectomy and coronoidotomy in right side. We suspected this deformity to be arised from unknown high fever in childhood. Ankylosis occured before mixed dentition period was main etiological factor of facial deformity. So, the earlier correction is the better result. It is to prevent recurrence of ankylosis and improve the prognosis that adequate bone resection, proper selection of interposing material and post-operative continuous forceful mandibular movement.
