BACKGROUND/OBJECTIVE: Judgement of nasolabial aesthetics in cleft lip and palate (CLP) is a vital component of assessment of treatment outcome. It is usually performed based on two-dimensional (2D) facial photographs. An increasing use of three-dimensional (3D) imaging warrants an assessment if 3D images can substitute 2D photographs during aesthetic evaluation. The aim of this study was to compare reliability of rating nasolabial appearance on 3D images and standard 2D photographs in prepubertal children.
Forty subjects (age: 8.8-12) with unilateral CLP treated according to a standardized protocol, who had 2D and 3D facial images were selected. Eight lay raters assessed nasal form, nasal deviation, vermilion border, and nasolabial profile on cropped 2D and 3D images using a 100-mm visual analogue scale (VAS). Additionally, raters answer two questions: 1. Do 2D or 3D images provide more information on nasolabial aesthetics? and 2. Is aesthetic evaluation easier on 2D or 3D images?
Intrarater agreement demonstrated a better reliability of ratings performed on 3D images than 2D images (correlation coefficients for 3D images ranged from 0.733 to 0.857; for 2D images from 0.151 to 0.611). The mean scores showed, however, no difference between 2D and 3D formats (>0.05). 3D images were regarded more informative than 2D images (P = 0.001) but probably more difficult to evaluate (P = 0.06).
Basal view of the nose was not assessed.
3D images seem better than 2D images for rating nasolabial aesthetics but raters should familiarize themselves with them prior to rating.
背景/目的：唇腭裂（CLP）患者鼻唇美学的评判是治疗效果评估的重要组成部分。通常基于二维（2D）面部照片进行评判。随着三维（3D）成像技术的日益广泛应用，有必要评估在美学评估中3D图像是否可以替代2D照片。本研究的目的是比较青春期前儿童3D图像和标准2D照片在鼻唇外观评分上的可靠性。
选择40例（年龄：8.8 - 12岁）按照标准化方案治疗的单侧唇腭裂患者，这些患者同时拥有2D和3D面部图像。8名非专业评分者使用100毫米视觉模拟量表（VAS）对裁剪后的2D和3D图像上的鼻形态、鼻偏斜、唇红缘和鼻唇轮廓进行评估。此外，评分者回答两个问题：1. 2D或3D图像在鼻唇美学方面提供的信息更多？2. 对2D还是3D图像进行美学评估更容易？
评分者内一致性表明，对3D图像进行评分的可靠性优于2D图像（3D图像的相关系数范围为0.733至0.857；2D图像的相关系数范围为0.151至0.611）。然而，平均得分显示2D和3D格式之间没有差异（>0.05）。3D图像被认为比2D图像提供的信息更多（P = 0.001），但可能更难评估（P = 0.06）。
未评估鼻的底面视图。
对于鼻唇美学评分，3D图像似乎优于2D图像，但评分者在评分前应熟悉3D图像。
