Background: In plastic and reconstructive craniofacial surgery, careful preoperative planning is essential. In complex cases of craniofacial synostosis, rapid prototyping models are used to simulate the surgery and reduce operating time. Recently, 3-D CT model surgery has been introduced for presurgical planning and prediction of the postoperative result. Objective: For simulation of craniofacial surgery a computer-based system was developed that allows visualization and manipulation of CT-data using computer graphics techniques. Surgical procedures in all areas of the bony skull can be performed interactively. Results: The case of a child with scaphocephalus is presented. Surgery is planned using the craniofacial surgery simulator described above. Conclusion: The computer-based interactive surgery simulation systems presented here allow precise visualization of craniofacial surgery. The accurate computer-aided 3-D simulation of bone displacements is also the prerequisite for transfer of the simulated surgery using a navigation system for surgery. Thus the preoperatively planned procedure could be transferred directly to the operating table. Copyright 2001 European Association for Cranio-Maxillofacial Surgery.
在整形与重建颅面外科手术中，细致的术前规划至关重要。在复杂的颅面骨缝早闭病例中，快速成型模型用于模拟手术并减少手术时间。近来，三维CT模型手术已被引入用于术前规划及术后结果预测。目的：为模拟颅面外科手术，开发了一种基于计算机的系统，该系统利用计算机图形技术实现CT数据的可视化及操作。颅骨所有区域的外科手术均可交互式进行。结果：呈现了一例舟状头畸形患儿的病例。使用上述颅面外科手术模拟器进行手术规划。结论：此处介绍的基于计算机的交互式手术模拟系统可实现颅面外科手术的精确可视化。骨移位的精确计算机辅助三维模拟也是使用手术导航系统进行模拟手术转移的前提条件。因此，术前规划的手术步骤可直接转移至手术台。版权所有2001欧洲颅颌面外科协会。
