中文摘要：

针对目前颌面外科手术前缺少必要的规划和模拟,临床手术操作对医生经验依赖程度较高的现状,将数字化设计和制造技术与医学工程相结合,构建针对复杂颌面外科手术的手术方案设计体系。集成基于CT的三维模型重建、镜像修复模型设计、手术辅助工具设计、模型快速成形制造等工程技术,实现基于虚拟模型的手术方案设计及基于实物模型的模型外科手术模拟,制订理想的手术方案,并通过辅助工具保证方案在临床手术中得到精确实施。22例手术方案临床成功应用表明,应用基于数字化设计与制造技术的手术方案设计系统,手术质量和效率都得到了提高。

英文摘要：

In maxillofacial surgery,surgical plan and simulation are rarely lacked before clinical operation,and experiences of surgeon are relied heavily.Aiming at this problem,digital design and manufacturing techniques such as image processing,three dimensional tissue reconstruction,surgical aid tool design and rapid prototyping manufacturing were applied into medical areas,to construct surgical plan design system for complicated maxillofacial surgery.With this system,surgical plan design based on virtual model and model operation simulation based on physical model can be realized,and ideal surgical treatment strategy can be acquired,and this strategy can be operated accurately in clinic with help of surgical aid tools.Total 22 successful clinical applications illustrate that,with sugary plan design system based on digital design and manufacturing techniques,the efficiency and quality of maxillofacial surgery can be improved effectively.
