Abstract：
Plastic surgeons routinely use 3D-models in their clinical practice, from 3D-photography and surface imaging to 3D-segmentations from radiological scans. However, these models continue to be viewed on flattened 2D screens that do not enable an intuitive understanding of 3D-relationships and cause challenges regarding collaboration with colleagues. The Metaverse has been proposed as a new age of applications building on modern Mixed Reality headset technology that allows remote collaboration on virtual 3D-models in a shared physical-virtual space in real-time. We demonstrate the first use of the Metaverse in the context of reconstructive surgery, focusing on preoperative planning discussions and trainee education. Using a HoloLens headset with the Microsoft Mesh application, we performed planning sessions for 4 DIEP-flaps in our reconstructive metaverse on virtual patient-models segmented from routine CT angiography. In these sessions, surgeons discuss perforator anatomy and perforator selection strategies whilst comprehensively assessing the respective models. We demonstrate the workflow for a one-on-one interaction between an attending surgeon and a trainee in a video featuring both viewpoints as seen through the headset. We believe the Metaverse will provide novel opportunities to use the 3D-models that are already created in everyday plastic surgery practice in a more collaborative, immersive, accessible, and educational manner.
摘要：
整形外科医生在临床实践中经常使用3D模型，从3D摄影和表面成像到放射学扫描的3D分割。然而,这些模型继续在扁平的2D屏幕上查看，这些屏幕不能直观地理解3D关系，并导致与同事合作的挑战。Metaverse已被提出作为基于现代混合现实耳机技术的应用的新时代，该技术允许在共享的物理虚拟空间中实时对虚拟3D模型进行远程协作。我们展示了Metaverse在重建手术中的首次使用，专注于术前计划讨论和培训。将HoloLens耳机与MicrosoftMesh应用程序配合使用，在我们的重建转复过程中,我们对从常规CT血管造影分割的虚拟患者模型进行了4个DIEP皮瓣的计划会话.在这些会议中,外科医生讨论穿孔器解剖和穿孔器选择策略，同时全面评估各自的模型。我们在视频中演示了主治外科医生和受训者之间一对一互动的工作流程，该视频具有通过耳机看到的两种观点。我们相信Metaverse将提供新的机会来使用已经在日常整形手术实践中创建的3D模型，身临其境,可访问,和教育方式。
