In order to get surgical simulation with lower radiation,less cost and real time operation,a visualizing system for intra-operative simulation and post-operative facial appearance prediction of orthognathic surgery was developed.By acquiring radiographs of three orthogonal views and facial mesh data,using a specialized registration procedure,applying mesh deformation algorithm based on radial basis function interpolation,exploiting a novel mesh cutting algorithm based on prism,the system reconstructed the patient's skull,simulated complex osteotomies,aligned reconstructed skull and face,and finally predicted post-operative facial appearance of patient.The simulation result to a clinical patient shows that the proposed system can be an assist of orthognathic surgeon to make preoperative plan and execute intra-operative procedure.
