【 摘 要 】

A corrective surgery known as the craniofacial surgery is important for the improvement of a patient’sappearance and in some cases a patient’s physical abilities in terms of speech. The postoperative softtissues prediction is often a hit considering the complex facial anatomy. Such surgical planning may bemade simpler and more precise with the use of computational modelling of the relevant area. This paperpresents a general framework for the simulation of soft tissue in order to predict the postoperative resultsof maxillofacial surgery based on the finite element method. Methods for the facial model preparationused in the analysis are described. A 3D facial model of the facial skin and the underlying lower jaw ismodelled from a patient-specific CT data. In conjunction with the representation of soft tissue mechanicalproperties and boundary assignment, the models were submitted for a contact analysis for acomputational postoperative appearance. Finally the simulation results are shown for the case study data.
