Abstract：Objective To evaluate the preoperative prediction accuracy and clinical application value of three dimensional(3D) printing technology in the management of multiple maxillofacial fractures.Methods Eight patients with multiple maxillofacial fractures in our hospital from Jun.2014 to Mar.2015 were chosen to undergo CT scanning with maxillofacial 3D reconstruction before operation.The data was input to 3D printer to yield rapid pro-totyping model with the same size of patients'maxillofacial regions.Simulations of fracture surgery and pre-forming of fracture fixation materials were conducted on the model to compare the consistency of model with the data obtained from real fracture operations.Results 3D printing models can accurately replicate the facial fractures.The actual fracture conditions of all patients were corresponding to preoperative prediction with operation time shortened signifi-cantly and good recovery of facial appearance and masticatory function.Conclusion With high precision,3D print-ing technique can be applied to the preoperative prediction of multiple maxillofacial fractures in order to improve the surgical accuracy,shorten the surgical time and achieve effective rehabilitation.
