Abstract
INTRODUCTION
Fractures of the zygomatic arch extended to the glenoid fossa are rare and seldom reported.
OBSERVATION
A 26-year-old man with a slightly dislocated fracture of the zygoma associated with trismus, and localized pain in the right Temporo-Mandibular Joint (TMJ) on palpation, but without any condylar fracture. The craniofacial CT scan revealed a fracture of the zygoma extended to the glenoid fossa. The treatment was an intraoral reduction of the zygoma and screw fixation of the glenoid fossa lateral region.
DISCUSSION
The risk of delayed healing by mobilization of the bone fragments was opposed to the risk of TMJ ankylosis due to a prolonged immobilization of the joint. Osteosynthesis of the fracture was finally chosen.
