Abstract

Zygomaticomaxillary complex fractures are very common in maxillofacial trauma and may be associated with fractures of the coronoid process. We report a case of dislocation of the coronoid process above a zygomaticomaxillary complex fracture locking the mandible. We also report the surgical management of this uncommon case and its follow-up.

Keywords: ZMC fracture; coronoid process; dislocation.
