摘要 目的:探讨3D打印技术在粉碎性颧骨颧弓骨折治疗中的应用价值。方法:选择2014年1月—2017年4月期间在西安交通大学口腔医院就诊的单侧粉碎性颧骨颧弓骨折21例。术前行薄层CT扫描,并将CT数据导入计算机辅助设计软件;进一步在计算机中将健侧颧骨颧弓镜像至患侧,最终打印出"复位"理想的患侧颧骨颧弓形态模型。在此模型上,进行内固定钛板预成型。术中利用预成型的内固定钛板引导骨段复位并最终完成内固定。术后行CT复查,三维测量颧骨颧弓位置并与术前设计位置进行比较,评估手术效果。采用SPSS 25.0软件包对测量数据进行配对t检验。结果:术后关键标志点间距同术前设计差异无统计学意义,手术效果满意。结论:3D打印技术有助于术前设计和植入物精确塑形,能有效提高单侧粉碎性颧骨颧弓骨折复位的精确性。 PURPOSE:To explore the validity of 3 D printing technique in the treatment of unilateral comminuted zygomatic bone fracture.METHODS:Twenty-one patients with unilateral comminuted zygomatic bone fracture were included in the present study,which were treated from hospital January 2014 to April 2017.All patients underwent CT scan and the data were imported in Mimics 10.01 software.The zygomatic bone of healthy side was mirrored to the fracture side to rebuild a'perfect'reduction model.Bone fixation plates were pre-modeled on the model printed by a 3 D printing machine and used for bone reduction and fixation during operation.Three dimensional measurements were performed to evaluate the validity of 3 D printing based on pre-and post-operative three dimensional CT model.SPSS25.0 software package was used to perform paired t test on the measured data.RESULTS:No significant difference were observed between postoperative CT model and preoperative'perfect'reduction model.All patients were satisfied with their facial appearance.CONCLUSIONS:3 D printing technique is helpful to improve the accuracy of reduction of unilateral comminuted zygomatic bone fracture via preoperative pre-modeling.
