To make three-dimensional computer-assisted elastic models for the face, we decided on five requirements: (1) an elastic texture like skin and subcutaneous tissue; (2) the ability to take pen marking for incisions; (3) the ability to be cut with a surgical knife; (4) the ability to keep stitches in place for a long time; and (5) a layered structure. After testing many elastic solvents, we have made realistic three-dimensional computer-assisted two-layer elastic models of the face and cleft lip from the computed tomographic and magnetic resonance imaging stereolithographic data. The surface layer is made of polyurethane and the inner layer is silicone. Using this elastic model, we taught residents and young doctors how to make several typical local flaps and to perform cheiloplasty. They could experience realistic simulated surgery and understand three-dimensional movement of the flaps.
为制作面部的三维计算机辅助弹性模型，我们确定了五个要求：（1）具有类似皮肤和皮下组织的弹性质地；（2）能够接受用于切口的笔标记；（3）能够用手术刀切割；（4）能够长时间保持缝线在位；（5）具有分层结构。在测试了多种弹性溶剂后，我们根据计算机断层扫描和磁共振成像立体光刻数据制作出了逼真的面部和唇裂三维计算机辅助双层弹性模型。表层由聚氨酯制成，内层由硅胶制成。使用这个弹性模型，我们教授住院医师和年轻医生如何制作几种典型的局部皮瓣并进行唇成形术。他们能够体验逼真的模拟手术并了解皮瓣的三维运动。
