In order to achieve a better functional and aesthetic reconstruction result, many studies for pre-surgical planning are employed to assist surgeons in the surgery, especially for computer-aided system that is widely used in recently. Most of methods for pre-surgical planning are performed by observing the geometry features of mandible defect portion, and then the number of fibular segment required to shape the original contour can be determined. However, this relies on vision measurement and model production. In order to simplify this process, this study aims to develop an automatic surgical planning system for mandibular reconstrcution using fibular flap. The study insists of two major parts, which are parameterization and reconstruction planning. In the parameterization, a mandible Stereo Lithograph (STL) model and fibula scan data will be parameterized into feature-defined structure points according to their geometry characteristics. A New STL model can be generated using structure points. For reconstruction planning, the structure parameters are used to determine the mandible defect and the orientation of fibula to reconstruct, and then to calculate for the optimal reconstruction solution. Finally, the simulation of osteotomy and reconstruction are performed in the virtual reality.
