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.
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.
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.
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.
借助当代计算机技术，创建虚拟手术环境（VSE）进行培训成为可能。本文描述了一种支持内镜颅底手术演练的患者特定虚拟鼻科学手术模拟平台。我们还分享了我们在选择病例方面的早期经验。
开发了一种鼻科学 VSE，具有高效的直接三维（3D）体绘制，在虚拟解剖结构的手术操作过程中提供同时的立体反馈，以及高保真触觉反馈。我们对 10 例接受各种鼻窦和颅底前手术的患者进行了回顾性分析，以评估鼻科学 VSE 复制实际术中发现的能力。
在所有 10 例患者中，模拟体验逼真到足以以类似于实际手术的方式进行解剖。在手术暴露、解剖特征和病变位置方面，相关性很好。
当前的鼻科学 VSE 具有足够的逼真度，可以实现鼻窦和颅底前的患者特定手术排练。需要进一步的验证研究来评估进行患者特定排练的益处。
