The zygornaticomaxillarx complex (ZMC) plays an important role in maintaining the structure and function of the face. The prominent convex shape of the ZMC makes it particularly vulnerable to trauma, resulting in a tetrapod fracture involving all four buttresses. ZMC fracture usually leads to local depressed deformities, even dysfunction such as limited mouth opening and diplopia. This article lescribes the etiology, clinical features, surgical approaches and postoperative complications of ZMC fractures based on our own clinical experiences and literature review. It is believed that lateral brow incision combined with intraoral incision can provide better access to ZMC fractures and avoid the disadvantages caused by coronal incision. This surgical approach leaves minimal scar and injury to the facial nerve, with better esthetic and functional outcomes. Supported by Shanghai Leading Academic Discipline Project (Grant No. Y0203).
颧上颌复合体(ZMC)在维持面部结构和功能方面起着重要作用。ZMC突出的凸形使其特别容易受到创伤,导致涉及所有四个支柱的四联骨折。ZMC骨折通常会导致局部凹陷畸形,甚至出现诸如张口受限和复视等功能障碍。本文基于我们自己的临床经验和文献综述,描述了ZMC骨折的病因、临床特征、手术方法及术后并发症。认为外侧眉弓切口联合口内切口能够更好地显露ZMC骨折,避免冠状切口带来的弊端。这种手术方法瘢痕最小,对面神经损伤小,具有更好的美学和功能效果。得到上海重点学科项目(批准号:Y0203)资助。
