Abstract
Objective To use the individual surface templates of craniomaxillofacial bone in accurate reduction and reconstruction of zygomatic-orbital-maxillar bone fracture. Methods Twenty-five cases of unilateral zygomatic-orbital-maxillar bone fracture were observed in this study. Preoperatively, craniomaxillofacial bones were scanned by CT and 3D surface reconstruction of skulls were performed. Then, 3D reconstructions of skull were performed through CT scans. Individual surface templates of fractured side craniomaxillofacial bone, made by technology of electronic computer-aided design (CAD) and rapid prototyping (RP) base on the CT data of unfractured side, were used to guide reduction and reposition of fractured and migrated zygomatic-orbital-maxillar complex (ZOMC) . Results Among all cases, the individual CAD templates, were well manipulated in surgery, guiding perfectly reposition and reconstruction of ZOMC. The postoperative horizontal asymmetric rates of each landmark are less than 3%. Conclusion On the basis of CAD and RP treatment, the individual templates can be perfectly applied to guide reposition and reconstruction of ZOMC.
