The introduction of intraoperative computed tomography and image-guided navigation have demonstrated some advantages for the correction of midfacial post-traumatic deformities. However, these methods still do not achieve satisfactory results. The authors sought to describe a novel method for the precise correction of complex midfacial post-traumatic deformities using three-dimensional printing customized surgical guides.
Ten patients with midfacial post-traumatic deformities admitted between January 15, 2018 and August 20, 2020 were included. To design the surgical guide for each patient, preoperative planning and simulation datasets were used as a virtual template. Each surgical guide comprised three-dimensional printing cutting guides and customized titanium plates to guide the osteotomy and repositioning of the fracture fragments intraoperatively. Reduction and fixation were confirmed by intraoperative navigation. Postoperative deviation chromatography analysis and clinical examination were conducted to evaluate the surgical outcome. All operations were successfully performed.
The average difference between the virtual plans and postoperative results was less than 1.5 mm. The 3- to 6-month follow-up evaluation demonstrated that symptoms were alleviated, and postoperative function and esthetics improved considerably.
Three-dimensional-printed customized surgical guides can accurately and effectively transfer the virtual surgical plan to the patient and could be considered an ideal and valuable option for this potentially complicated procedure.
术中计算机断层扫描和图像引导导航已显示出一些优势，可用于矫正外伤性鼻骨和面中部畸形。然而，这些方法仍未达到满意的效果。作者旨在描述一种使用三维打印定制手术导板精确矫正复杂外伤性鼻骨和面中部畸形的新方法。
纳入 2018 年 1 月 15 日至 2020 年 8 月 20 日期间收治的 10 例外伤性鼻骨和面中部畸形患者。为每位患者设计手术导板，使用术前规划和模拟数据集作为虚拟模板。每个手术导板由三维打印切割导板和定制钛板组成，用于术中引导骨折块的截骨和复位。术中导航确认复位和固定。术后通过偏离色谱分析和临床检查评估手术结果。所有手术均成功完成。
虚拟计划与术后结果的平均差异小于 1.5 毫米。3 至 6 个月的随访评估表明，症状得到缓解，术后功能和美观明显改善。
三维打印定制手术导板可以将虚拟手术计划准确有效地转移到患者身上，对于这种复杂的手术，它可以被认为是一种理想且有价值的选择。
