背景：借助现代计算机技术，可以创建用于培训的虚拟手术环境（VSE）。本文介绍了一个病人特定的虚拟神经外科手术模拟平台，支持排练内窥镜颅底手术。我们也分享我们的早期经验，选择cases.Methods：一个神经外科VSE的开发，具有高效的直接三维（3D）体积渲染器，同时在虚拟解剖手术操作的立体反馈，以及高保真触觉反馈。我们进行了回顾性分析，对10例患者进行了各种形式的窦和腹侧颅底手术，以评估的神经外科VSE的能力，以复制实际的术中findings.Results：在所有10例，模拟的经验是现实的，足以执行解剖在实际手术中以类似的方式。优秀的相关性被发现在手术暴露，解剖特征，和位置的pathology.Conclusion：目前的神经外科VSE显示足够的现实主义，让患者特定的手术排练的窦和腹侧颅底。需要进一步的验证研究来评估进行患者特定排练的好处。(C)2017 ARS-AAOA，LLC.
Background: With the help of contemporary computer technology it is possible to create a virtual surgical environment (VSE) for training. This article describes a patient-specific virtual rhinologic surgical simulation platform that supports rehearsal of endoscopic skull-base surgery. We also share our early experience with select cases.Methods: A rhinologic VSE was developed, featuring a highly efficient direct 3-dimensional (3D) volume renderer with simultaneous stereoscopic feedback during surgical manipulation of the virtual anatomy, as well as high-fidelity haptic feedback. We conducted a retrospective analysis on 10 patients who underwent various forms of sinus and ventral skull-base surgery to assess the ability of the rhinologic VSE to replicate actual intraoperative findings.Results: In all 10 cases, the simulation experience was realistic enough to perform dissections in a similar manner as in the actual surgery. Excellent correlation was found in terms of surgical exposure, anatomical features, and the locations of pathology.Conclusion: The current rhinologic VSE shows sufficient realism to allow patient-specific surgical rehearsal of the sinus and ventral skull base. Further validation studies are needed to assess the benefits of performing patient-specific rehearsal. (C) 2017 ARS-AAOA, LLC.
