This study investigates and compares the reliability and reproducibility of two facial anthropometric methods about external nasal angles, 3D imaging and conventional 2D photography. 2D photograph images and 3D images about external nose of 30 volunteers were taken using digital camera and Morpheus 3D scanner. To evaluate intra-rater reliability, each images were taken over two different days for each subject by the same researcher. To evaluate inter-rater reliability, another researcher took each images for each subject on the first day. The reliability of each method for measuring 4 external nasal angle is obtained using intraclass correlation coefficient (ICC) and compared. Inter-rater and intra-rater reliability of both 3D imaging and 2D photography had excellent agreement in all 4 nasal angles. In the nasofacial angular parameter, Inter-rater ICC, 2D photography was significantly higher than 3D imaging. Result of intra-rater ICC also showed both 3D imaging and 2D photography had good reliability in all 4 nasal angles. Similar to those of inter-rater ICC, nasofacial angular parameter showed statistically significant differences between 3D imaging and 2D photography. In terms of reliability, both 2D and 3D showed appropriate anthropometric results and considering its own advantage, each methods can be used complementarily.
本研究调查并比较了两种面部人体测量方法（三维成像和传统二维摄影）在测量鼻外角度方面的可靠性和可重复性。使用数码相机和Morpheus 3D扫描仪拍摄了30名志愿者鼻子外部的二维照片图像和三维图像。为了评估评分者内信度，同一名研究人员在两天内为每个受试者拍摄图像。为了评估评分者间信度，另一名研究人员在第一天为每个受试者拍摄图像。使用组内相关系数（ICC）获得两种测量4个鼻外角度方法的可靠性并进行比较。在所有4个鼻角中，三维成像和二维摄影的评分者间信度和评分者内信度都具有极好的一致性。在鼻面角参数方面，评分者间ICC，二维摄影显著高于三维成像。评分者内ICC结果也显示，三维成像和二维摄影在所有4个鼻角中都具有良好的可靠性。与评分者间ICC类似，鼻面角参数在三维成像和二维摄影之间存在统计学显著差异。在可靠性方面，二维和三维都显示出合适的人体测量结果，考虑到各自的优势，每种方法可以互补使用。
