Zygomatic fractures can be associated with functional and esthetic problems. Recent improvements in surgical techniques and materials have enabled stable fixation of zygmomatic fractures. Multiple-point fixation is most commonly used for internal fixation. Generally, reduction and fixation are performed through lateral brow, subciliary, temporal, or intraoral incisions (three-point fixation). Our experience indicates that postoperative scarring and sensory disturbances are caused by a subciliary incision with inferior orbital rim fixation. It is thus recommended that inferior orbital rim fixation with mini- or microplates be avoided. In patients in whom the fracture does not involve the orbital floor, reduction of the zygoma and zygomatic arch through a temporal incision is performed at this institution. Fixation of the lateral zygomaticomaxillary buttress and anterior wall of the maxilla with miniplates through an intraoral incision is also performed. If necessary, zygomaticofrontal suture fixation with a miniplate or wire is performed through a lateral brow incision. The status of inferior orbital rim reduction is confirmed by palpitation. Inferior orbital rim fixation with mini- or microplates is recommended for reduction of comminuted fractures and orbital floor fractures with herniation of internal orbit components. Patients who did not undergo inferior orbital rim fixation were free of inferior orbital rim deformity, diplopia, and postreduction rotation.
