Zygomaticomaxillary (ZMC) fractures are the second most common facial fractures after nasal bone fractures. The zygoma, with its location and multiple points of articulations, lends itself to both facial structure and esthetics. Secondary ZMC deformities are complications of inadequate primary correction, delayed repair, or lack of repair. Secondary revisions of ZMC aim to correct ZMC displacement and projection and to address orbital discrepancies. Extensive correction involving significant orbital and malar defects requires zygomatic repositioning osteotomies and would greatly benefit from the utilization of virtual surgical planning, intraoperative navigation, and imaging. Minor corrections in malar projection can be corrected by onlay grafting and soft tissue augmentation and resuspension. Isolated or minor orbital corrections can be managed by autogenous or alloplastic material to restore lost orbital volume and anatomy.
颧上颌骨（ZMC）骨折是仅次于鼻骨骨折的第二常见面部骨折。颧骨因其位置和多个关节点，对面部结构和美学都有影响。ZMC继发性畸形是初次矫正不足、延迟修复或未修复的并发症。ZMC的二次修复旨在纠正ZMC的移位和突出，并解决眼眶差异。涉及严重眼眶和颧骨缺损的广泛矫正需要进行颧骨重新定位截骨术，而利用虚拟手术规划、术中导航和成像将大有裨益。颧骨突出的轻微矫正可通过植骨和软组织增大及重新悬吊来纠正。孤立的或轻微的眼眶矫正可通过自体或异体材料来处理，以恢复丢失的眼眶容积和解剖结构。
