For "minimally invasive" approaches to a deep-lying skull base lesion, the bone opening must be precisely placed and adequately wide to accomplish the surgical goal. Surgical rehearsal in virtual reality (VR) can generate navigation-integrated augmented reality (AR) templates to ensure precise surgical openings. In this video, the authors used AR templates for the transpalpebral, transorbital approach for intradural tumors. VR renderings of patient-specific anatomy were used in surgical rehearsal. The optimal openings were saved and, at surgery, projected into the eyepiece of the navigation-tracked microscope. The template enhanced the planning of the incision and soft-tissue exposure and guided the drill toward the target.

对于深部颅底病变的“微创”入路，骨窗必须精确放置且足够宽，以实现手术目标。虚拟现实（VR）中的手术预演可以生成与导航集成的增强现实（AR）模板，以确保精确的手术开口。在本视频中，作者将AR模板用于经睑、经眶入路治疗硬膜内肿瘤。手术预演中使用了患者特异性解剖结构的VR渲染。保存最佳开口，并在手术时投射到导航跟踪显微镜的目镜中。该模板增强了切口和软组织暴露的规划，并引导钻头朝向目标。视频可在此处找到：https://stream.cadmore.media/r10.3171/2021.10.FOCVID21172 。
