我们提出了一个原型的面部手术模拟系统的手术规划和面部变形的预测。我们使用基于物理学的人类头部模型。我们的头部模型具有由软组织和颅骨组成的3D分层结构，由精确的3D CT患者数据构建。本研究的目的是分析正颌外科手术后下颌骨位置的变化与面部形态的关系，并模拟出精确的三维面部形态。在实验中，我们使用我们的模型来预测下颌骨多颌畸形患者手术后的面部形状。仿真结果与手术后的实际人脸图像对比表明，该方法具有一定的实用性。
We propose a prototype of a facial surgery simulation system for surgical planning and the prediction of facial deformation. We use a physics-based human head model. Our head model has a 3D hierarchical structure that consists of soft tissue and the skull, constructed from the exact 3D CT patient data. Anatomic points measured on X-ray images from both frontal and side views are used to fire the model to the patient's head.The purposes of this research is to analyze the relationship between changes of mandibular position and facial morphology after orthognathic surgery, and to simulate the exact postoperative 3D facial shape. In the experiment, we used our model to predict the facial shape after surgery for patients with mandibular prognathism. Comparing the simulation results and the actual facial images after the surgery shows that the proposed method is practical.
