Nowadays, there is a trend towards computer-aided oral and maxillofacial surgery. However, due to complicated preoperative planning, traditional neurosurgery-orientated navigation systems are not suitable and have to be adapted.
A surgical navigation system is presented for oral and maxillofacial surgery, named AccuNavi, which integrates 3D medical modelling, preoperative surgical planning and intraoperative tracking. Various algorithms were introduced, for each of which a set of dynamic link libraries (DLLs) were developed using C++, as well as the VTK and ITK, via object-orientated programming methodology, allowing for expandability, accessibility and maintainability in our system.
The advantage of AccuNavi is validated through clinical applications, especially in a case report about the planning and subsequent precise treatment of old zygomatic fractures. The postoperative 3D-reconstructed CT image demonstrated that the fractured zygoma was fixed in the appropriate position and orientation.
The clinical application demonstrates the feasibility and reliability of AccuNavi, and it can be extended to various areas in oral and maxillofacial surgery.
如今，计算机辅助口腔颌面外科手术有发展趋势。然而，由于术前计划复杂，传统的神经外科导向式导航系统并不适用，需要进行适应性改进。
我们提出了一种名为 AccuNavi 的口腔颌面外科手术导航系统，它集成了 3D 医学建模、术前手术规划和术中跟踪功能。我们引入了各种算法，并使用 C++、VTK 和 ITK 通过面向对象编程方法为每个算法开发了一组动态链接库 (DLL)，从而实现了系统的可扩展性、可访问性和可维护性。
AccuNavi 的优势通过临床应用得到了验证，特别是在一份关于陈旧颧骨骨折的规划和后续精确治疗的病例报告中。术后的 3D 重建 CT 图像显示，骨折的颧骨被固定在合适的位置和方向。
临床应用证明了 AccuNavi 的可行性和可靠性，它可以扩展到口腔颌面外科的各个领域。
