Based on physical laws, stage of technical development and the user's individual skills a number of possible errors have to be considered for the application of CAS in paranasal sinus and anterior skull base surgery.
PATIENTS/METHODS: Based on our experiences of 436 navigated cases hard- and software errors, errors of image acquisition and transfer, errors of patient registration, user related errors as well as strategic errors are analyzed.
Any hindrance of the camera field leads to a limitation of functionality of optical systems in the same extent as electromagnetic systems can be affected by ferromagnetic materials. The mode of image acquisition is dependent from the CAS-system involved. The reconstruction algorithm requires particular attention. The patient registration based on the headset proved to be reliable for endonasal sinus surgery.
In dealing with navigation devices in paranasal and anterior skull base surgery the user must pay critical attention to possible malfunction in order to guarantee a successful image guided surgical procedure.
基于物理定律、技术发展阶段以及用户的个人技能，在鼻旁窦和前颅底手术中应用计算机辅助手术（CAS）时必须考虑一些可能出现的错误。
患者/方法：基于我们436例导航病例的经验，对硬件和软件错误、图像采集与传输错误、患者配准错误、用户相关错误以及策略性错误进行了分析。
摄像头视野的任何阻碍都会导致光学系统功能受限，其程度与电磁系统受铁磁性材料影响的程度相同。图像采集模式取决于所涉及的CAS系统。重建算法需要特别关注。基于头戴设备的患者配准在鼻内鼻窦手术中被证明是可靠的。
在鼻旁窦和前颅底手术中使用导航设备时，用户必须密切关注可能出现的故障，以确保图像引导手术的成功进行。
