The main cause of decreased mouth opening in patients suffered from trauma is bony or fibrous ankylosis of
temporomandibular joint, but other causes such as fibrous or bony union of zygoma and / or maxilla to the
coronoid process of the mandible must be considered in preoperative management of such cases.
Bony union of the mandible to the maxilla and zygoma is rare. In this report, one case, a victim of
earthquake (Bam city, December 2002) with the diagnosis of traumatic maxillomandibular fusion and the
