On constitutive modeling of soft tissue for the long-term prediction of cranio-maxillofacial surgery outcome

Abstract In this paper, we discuss physically based approaches to the modeling of deformable soft tissue for the long-term prediction of patient's postoperative appearance in cranio-maxillofacial (CMF) surgery simulations. Since the biomechanical properties of living tissues and their numerical modeling are, in general, very complex, our focus is on the investigation of qualitative and quantitative differences between different physical models for the range of boundary value problems (BVP) typically appear in cranio-maxillofacial surgery.
