中文摘要

美容鼻整形通常依赖术中参考图像来帮助实现患者期望的美学效果。然而，这些图像通常以二维（2D）格式显示，这过度简化了三维（3D）鼻部解剖结构，并要求外科医生将注意力从手术区域转移开。增强现实（AR）技术可能通过将患者特定的3D全息图像投射到外科医生的视野中，提供实时空间可视化，从而解决这些限制。本文描述了一个使用3D面部成像系统和头戴式混合现实显示器将AR整合到美容鼻整形工作流程的方案。术前获取3D面部图像，与患者共同变形以代表期望的手术结果，导出为全息模型，并在术中显示以与手术区域进行视觉比较。该方案已成功纳入手术工作流程，允许外科医生在术前规划和术中评估期间在真实空间中操作全息模型。该方案为将AR纳入美容鼻整形提供了一个可重复的工作流程，并可能增强术中可视化、支持手术决策，并促进术前规划与术中解剖结构之间的比较。

英文摘要

Cosmetic rhinoplasty often relies on intraoperative reference images to help achieve the patient's desired aesthetic outcome. However, these images are typically displayed in a two-dimensional (2D) format, which oversimplifies three-dimensional (3D) nasal anatomy and requires the surgeon to divert attention away from the operative field. Augmented reality (AR) technology may address these limitations by projecting patient-specific 3D holographic images into the surgeon's field of view, providing real-time spatial visualization. This article describes a protocol for integrating AR into the cosmetic rhinoplasty workflow using a 3D facial imaging system and a head-mounted mixed-reality display. Preoperative 3D facial images are acquired, collaboratively morphed with the patient to represent the desired surgical outcome, exported as holographic models, and displayed intraoperatively for visual comparison with the surgical field. The protocol was successfully incorporated into the surgical workflow, allowing surgeons to manipulate holographic models in real space during preoperative planning and intraoperative assessment. This protocol provides a reproducible workflow for incorporating AR into cosmetic rhinoplasty and may enhance intraoperative visualization, support surgical decision-making, and facilitate comparison between preoperative planning and intraoperative anatomy.
