Reconstruction of the zygomatic arch using a mandibular adaption plate.

Zygomatic complex fractures are one of the most common facial fractures treated by maxillofacial surgeons. Because of the importance of the zygomatic complex in midfacial skeletal orientation, comminuted zygomatic arch fractures can lead to significant morbidity and deformity. Common repair modalities include closed reduction via a Gilles approach, open reduction and internal fixation with screws and/or plating systems, primary bone grafting, and/or biosynthetics. In patients with significant comminution and arch defects, who are poor candidates for bone grafting, reconstruction can be difficult. In this clinical report, we present 2 patients with comminuted zygomatic arch fractures and significant bony defects, who were reconstructed with mandibular adaption plates alone without primary bone grafting. Over a mean follow-up period of 12.5 months, both patients healed well without any complications and had acceptable cosmetic outcomes.
