Intraoperative videography is widely used to record rhinoplasty procedures, yet little is known about the optimal surgical vantage points at critical procedural steps. To assess commonly used camera angles in public and proprietary intraoperative rhinoplasty videos and discuss approaches to obtaining these viewing angles. Public and propriety rhinoplasty videos were reviewed and categorized based on procedure type, specific area(s) of focus, and camera angles utilized at a series of critical operative steps. The most commonly used camera angles were recorded and assessed based on surgical field visualization and the authors' personal recording experiences. Of the 114 videos that met inclusion criteria, 49 were full-length open rhinoplasty procedures, 20 full-length endonasal rhinoplasty procedures, 17 tip techniques, 8 opening techniques, 7 fashioning grafts, 7 osteotomies, and 6 cartilage harvests. With respective to footage acquisition, the upward camera angle was most frequently used for recording, and endoscopic view was least frequently used. These findings demonstrate that there is extensive variability in camera angles between surgical films. Moreover, many of these camera angles are insufficient due to obstruction by surgical staff, inability to visualize deep structures, and difficulty capturing the three-dimensional nasal framework. A guide indicating the best viewing angles for different aspects of the procedure would be useful to optimize educational videos.
术中录像被广泛用于记录鼻整形手术，但对于关键手术步骤的最佳手术视角知之甚少。本研究旨在评估公共和专有的术中鼻整形录像中的常用摄像角度，并讨论获得这些观察角度的方法。对公共和专有的鼻整形录像进行了回顾和分类，依据手术类型、特定关注区域以及在一系列关键手术步骤中使用的摄像角度。根据手术视野的可视化和作者的个人录制经验，记录并评估了最常用的摄像角度。在符合纳入标准的 114 个视频中，有 49 个是全长开放式鼻整形手术，20 个是全长经鼻内镜鼻整形手术，17 个是鼻尖技术，8 个是切口技术，7 个是塑造移植物，7 个是截骨术，6 个是软骨采集术。就拍摄角度而言，向上拍摄的角度是最常用于记录的角度，而内镜视角是最不常用的视角。这些发现表明，手术影片中的摄像角度存在广泛的差异。此外，由于手术人员的阻碍、无法可视化深部结构以及难以捕捉三维鼻架，许多这些摄像角度是不够的。一个可以指示不同手术方面最佳观察角度的指南，对于优化教育视频是有用的。
