摘要：

背景：由于颅颌面部骨骼解剖关系的复杂性，传统诊疗方法不能准确再现颅颌面部畸形的特点，更无法进行术前手术模拟。数字化模型外科技术可以提供给医生一个真实头颅的仿体，反应头颅结构的细节，能够更准确地解决颅颌面部修复对称性等难题。
目的：观察数字化外科技术在颅颌面复杂畸形修复重建中的临床应用效果。
方法：针对四川大学华西口腔医院2008/2009收治的7例复杂颅颌面畸形患者利用CT断层扫描得到颅颌面骨三维数据，通过计算机辅助设计并结合三维重建技术，对畸形进行修复前精确诊断、手术模拟设计，并通过快速成型技术和反求工程技术制作出三维头颅模型及个性化修复体，实现畸形的精确化修复。
结果与结论：基于计算机辅助设计-计算机辅助制造技术的个体数字化修复技术能够完成颅颌面部畸形修复体的设计和制造，可以提高手术精度，缩短手术时间，降低手术风险，改善治疗效果，明显提高了复杂颅颌面外科手术的精确性。提示数字化外科技术针对复杂颅颌面畸形修复重建病例有重要的临床实用价值。

Abstract:

BACKGROUND: Because of the complexity of skeleton anatomy relationship of cranio-maxillofacial region, traditional methods cannot exactly exhibit the characteristics of cranio-maxillofacial region deformities, and cannot simulate preoperative surgery. Digital model surgery technique can provide a real cranial phantom, reflect details of skull structure, and exactly solve some problems such as cranio-maxillofacial repair symmetry.
OBJECTIVE: To explore clinical application effects of individual digital surgery in reconstruction and repair of cranio-maxillofacial complex deformities.
METHODS: A total of seven patients with cranio-maxillofacial complex deformities were selected from West China Stomatology Hospital, Sichuan University between 2008 and 2009. CT scanner was employed to scan the patient heads and faces and to obtain three-dimensional data. Through the computer aid design combined with three-dimensional reconstruction, preoperative precise diagnosis of cranio-maxillofacial anomalies and surgery simulation design were successfully performed. Meanwhile, three-dimensional bionic cranium models and individual prosthesis could be fabricated with reverse engineering and rapid prototyping techniques, which resulted in the well restoration of complex deformity.
RESULTS AND CONCLUSION: Based on computer aid design-computer aid manufacture technique, the individual digital surgery will significantly promote the accuracy in cranio-maxillofacial plastic surgery and increase the clinical therapy effects. What’s more, it simplified the operative procedure, shorten operation time and decrease surgical risk. These suggested that individual digital surgery possesses high clinical practical value in reconstruction and repair of cranio-maxillofacial complex deformity.
