摘　　要：目的:探讨利用螺旋CT建立唇裂畸形计算机仿真模型的方法,建立一适用于唇裂手术模拟及术后面型预测的唇裂畸形计算机仿真模型。方法:利用薄层螺旋CT获取原始数据,利用面向对象的开源软件环境VTK(Visualization Toolkit)技术建立可视化模型,利用Visual C++编写质点弹簧模型程序并使之与VTK显示结合。结果:用质点弹簧模型及VTK技术成功建立出一个具有软组织生物力学特性的唇裂畸形模型,并且较大程度简化了运算过程,提高运算速度。结论:该模型有较好的力学和几何相似性,为唇裂手术模拟提供了一个研究平台。Objective To develop a A 3-month-old unilateral cleft lip, meshes of cleft lip were generated model by Visual C^＋＋. Results The computer-based model for planning and performing cleft lip repair. Methods alveolus and plate patient was previously CT scanned. High-resolution 3D by VTK technology. The visualization model was integrated with mass spring model of cleft lip was instilled with physical properties of soft tissue and the calculation was accelerated by simplifying the process. Conclusion This model combined with mass-spring model, boasting of both mechanical and geometric similarity, could provide a new method for planning and performing cleft lip repair.
