ABSTRACT
Objective To investigate the application of numerical simulation technique in supraorbital and frontal osseous defect.Methods The data of the patients with complex supraorbital and frontal osseous defects were obtained by helix CT scan.Numerical model based on the data was built up by computer.And the true model was produced by Rapid Prototyping.Being stimulated before this operation.the model was directly used in the operation.Results All of these 12 patients(one of defect of brow,four fracture of brow and zygoma,seven of old fracture of brow and zygoma)in this study were satisfied and their brows were symmetry after operation.All of them were satisfied after 1 or 2 years,without implantation exposure and transfiguration except one with infection.Conclusion Based on numerical technique difficulties of repairing,complex supraorbital and frontal osseous defect could be resolved by such process as collecting the bone data,stimulating operation by true models,and producing implantation before the operation.The accuracy of these operations can be improved.
