Standardized, high-quality, preoperative photographs of the nose are critical for preoperative rhinoplasty planning, comparative postoperative assessment, and demonstration of surgical results. To produce these high-quality, reproducible photographs, it is essential to standardize lighting, to properly position the patient in standard views, to avoid lens distortion, and to maintain consistent camera-to-subject distances. Traditional photographic standards have been well documented in the literature; however, most do not address digital photography, and none address digital photography for rhinoplasty. Certain variables in digital photography that are not present in 35-mm photography can be critical to the appearance of the final image. Variables such as image color and contrast (which usually vary between digital cameras), focal length differences between 35-mm and most digital cameras, the effect of resolution and compression on image quality, and the effect of the printing method used can affect the appearance of the external anatomy of the nose in the final print or image. Lack of detail in the external nasal anatomy becomes an issue if the surgeon uses the photograph intraoperatively for reference, as the authors do. Initially, the authors experienced difficulties with observing subtleties in the tip-defining points and tip anatomy using digital photography when compared with our traditional methods of 35-mm photography. The lack of detail in the external anatomy was most prevalent in the frontal and basal views. Thus, the authors have since tailored their photographic methods to document the rhinoplasty patient to maximize the visual information of the external nasal anatomy in the photographic and the printed image. This article is intended to review the photographic principles for standardized rhinoplasty photography, address the additional considerations necessary when using digital photography, discuss the printing variables that can affect overall quality of the printed image, and discuss the authors' new method of photographing the rhinoplasty patient.
标准化、高质量的术前鼻部照片对于鼻整形术前规划、术后对比评估以及手术效果展示至关重要。为了拍摄出这些高质量、可重复的照片,必须对光线进行标准化,让患者在标准视角下处于正确位置,避免镜头畸变,并保持相机与拍摄对象的距离一致。传统摄影标准在文献中已有详尽记载;然而,大多数标准并未涉及数码摄影,更没有针对鼻整形的数码摄影标准。数码摄影中存在一些35毫米摄影中没有的变量,这些变量对于最终图像的外观可能至关重要。诸如图像颜色和对比度(通常因数码相机而异)、35毫米相机与大多数数码相机之间的焦距差异、分辨率和压缩对图像质量的影响以及所使用的打印方法的影响等变量,都可能影响最终打印件或图像中鼻子外部解剖结构的外观。如果外科医生像作者一样在手术中使用照片作为参考,那么鼻外部解剖结构缺乏细节就会成为一个问题。最初,与我们传统的35毫米摄影方法相比,作者在使用数码摄影观察鼻尖界定点和鼻尖解剖结构的细微之处时遇到了困难。外部解剖结构缺乏细节在正面和底面视图中最为普遍。因此,作者此后调整了他们拍摄鼻整形患者的摄影方法,以在照片和打印图像中最大限度地呈现鼻外部解剖结构的视觉信息。本文旨在回顾标准化鼻整形摄影的摄影原则,阐述使用数码摄影时所需的额外注意事项,讨论可能影响打印图像整体质量的打印变量,并介绍作者拍摄鼻整形患者的新方法。
