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. |
