Abstract
surgery planning and simulation Abstract: Anatomy-based facial tissue modeling for surgical simulation is a field whose time has come. Real-time facial animation has been created in the last few years using models based on the anatomical structure of the human skin. Anatomy-based models are also under development in the field of medical visualization, with which facial surgery can be realistically simulated. In this article we present an anatomy-based 3D finite element tissue model. Integrated into a computer-aided surgical planning system this model allows the precise prediction of soft tissue changes resulting from the realignment of the underlying bone structure. The model has already been used in our Department of Oral and Maxillofacial Surgery and has improved craniofacial surgical planning procedures. The model is described in detail and surgical simulation results are shown and discussed. 1
