摘要:
[摘要]目的：通过评估手术导航技术辅助治疗颧骨颧弓骨折的精确度，探讨其在颌面部手术治疗中的应用价值。方法：选择
2015年1月-2018年11月在西安交通大学口腔医院就诊的单侧颧骨颧弓骨折患者19例。术前行薄层CT扫描，并将CT数据导入
手术导航术前规划软件。在手术规划系统中选择健侧颧骨颧弓结构并镜像至患侧，镜像的范围大于患侧骨折所累及范围，一
般情况下镜像体范围至少上至眶上缘，下达颧牙槽嵴，后至颧弓根部。通过进一步微调镜像体设计出骨折“复位”的理想位
置，再将设计好的模型导入手术导航仪并在术中辅助引导骨折复位固定。术后均行CT复查，通过两种方式评估手术导航的精
确性。方式一：将术后CT数据导入术前设计软件，经过图像融合后测量术后患侧颧骨颧弓的位置与术前设计的差异；方式
二：通过在术后CT上测量并对比双侧颧骨的位置评估双侧颧骨的对称性。结果：术后关键标志点间距同术前设计差异不超过
2mm，术前术后差异不具有统计学意义，手术效果满意。结论：手术导航技术辅助单侧颧骨颧弓骨折复位固定具有良好的精
确度。

Abstract: Objective To evaluate the accuracy and benefits of surgical navigation technology in the treatment of zygomatic arch
fracture. Methods From January 2015 to November 2018, nineteen patients diagnosed with unilateral zygomatic fracture were
selected in the Stomatological Hospital of Xi’an Jiaotong University. Thin slice CT scans were performed before operation,
and CT data were imported into the preoperative planning software of surgical navigation. In the surgical planning system, the
zygomatic arch structure of the healthy side is selected and mirrored to the affected side. The scope of the mirror images was
larger than that of the affected side. Generally, the scope of the mirror part should include at least the upper orbital margin,
the zygomatic alveolar ridge and the root of zygoma. The ideal positions of fracture reduction were designed by further finetuning
of the mirror body, and then the designed models were introduced into the surgical navigator and used in guiding fracture
reduction and fixation during the operation. Postoperative CT examination was performed to evaluate the accuracy of surgical
navigation in two ways. Method 1: The post-operative CT data were introduced into the preoperative design software, and the
difference between preoperative design and postoperative zygomatic arch position were measured after image fusion. Method
2: The symmetry of bilateral zygomatic bones was evaluated by measuring and comparing the position of bilateral zygomatic
bones on post-operative CT. Results The distances of the key markers between the preoperative design and postoperative
zygoma were less than 2 mm. No significant difference was observed between the preoperative and the postoperative zygomatic
position. Conclusion Surgical navigation is accurate and reliable for assisted reduction and fixation of unilateral zygomatic
arch fracture.
