目的探索应用计算机三维重建结合快速成型技术,设计并制造个性化颅耳角支撑物的可行性。方法对1例拟行颅耳角重建的先天性小耳畸形患者,进行全头颅CT扫描,获取CT数据,在PC机上进行三维重建和设计,通过快速成型技术打印出实体模型。结果获得了个性化的骨水泥颅耳角支撑物。结论应用计算机三维重建和快速成型技术可实现个性化颅耳角支撑物的设计和制造。

Objective To explore the feasibility of the design and manufacture of a personalized wedge by three-dimen-sional reconstruction technology and rapid proto-typing technology. Methods The head CT scan was performed on a patient with congenital microtia who was prepared for the auriculocephalic angle reconstruction. The 3D image was reconstructed by the CT data and the model of the wedge was designed. Then it was printed by the rapid proto-typing technology. Results A personalized EH composite wedge was acquired. Conclusion It is realizable to design and manufacture a personalized wedge by three-dimensional reconstruction technology and rapid proto-typing technology.
