The aim of this study was to present a treatment protocol for the individual repair of post-traumatic maxillofacial bone defects with vascularized flaps assisted by digital techniques. This study reviewed 20 patients with post-traumatic maxillofacial bone defects who underwent reconstruction with composite vascularized bone flaps assisted by digital techniques between April 2009 and July 2019. Preoperative computed tomography (CT) data were imported into ProPlan CMF software to complete virtual fracture reduction and reconstruction. Surgical navigation, three-dimensionally (3D) printed surgical plates, and prefabricated titanium mesh/plates were used to guide the actual surgery. All patients underwent open reduction and internal fixation and reconstruction surgery in one stage. CT data obtained at 1 week postoperative were imported into Geomagic Control software to evaluate the accuracy of the virtual surgical plan. The mean follow-up interval was 24 months (range 6-96 months). Donor and recipient site morbidity and second-stage procedures to rehabilitate the dentition and cosmetic organs were recorded. The flap success rate was 100%. Nine patients had deep circumflex iliac artery flaps and eleven patients had fibula flaps. The accuracy of computer-assisted surgery was 4.4±0.8mm. There were no postoperative complications. This study is novel in presenting a treatment protocol for individual computer-assisted reconstruction for post-traumatic maxillofacial bone defects with vascularized flaps.
