【摘要】：目的本研究的目的是采用三维立体摄影技术采集中国北方汉族年轻成人面部三维图像并进行面部数据测量,初步建立该人群面部形态特征的正常值,比较性别间面部形态差异,为临床面部数字化评估提供新方法和参考依据。方法共招募100例(男、女各50例)20-29岁、正常BMI范围、面部外形正常的中国北方汉族成人作为研究对象。使用VECTRA H1三维成像系统(Canfield Scientific Inc,USA)采集面部三维图像,利用三维图像测量面部32个线性指标和1个角度,计算4个比值。所有的拍摄和测量由同一名研究者完成,选择10幅(男、女各5幅)三维图像重复测量,采用组内相关系数(ICC)进行检验者内误差分析。采用两独立样本t检验比较男、女间差异,采用配对t检验比较面部左、右侧差异。结果检验者内误差分析显示研究者对所有项目的测量一致性良好(ICC值均0.80)。男性面部测量值总体而言大于女性,有16个线性测量指标(眼外角间宽、左右眼裂宽、眼内角间宽、鼻宽、鼻高、鼻长、鼻深、全上唇高、口宽、唇峰宽度、上唇皮肤部高度、形态面长、面宽、下面长、耳屏间宽)、2个比值(鼻宽/口宽、形态面指数)以及7组面深度指标(眶上面深、上1/3面深、外眦-耳屏深度、中1/3面深、口角-耳屏深度、颏上点-耳屏深度、下1/3面深)的性别间差异具有统计学意义(P0.05)。眼外角间宽、鼻宽、鼻高、鼻长、形态面长、面宽、下面长、耳屏间宽及7组面深度指标的性别间差异存在临床显著性(平均差异3mm)。结论本研究建立了中国北方汉族成人面部形态的正常参考值并比较了男女性面部形态差异,可为面部重建、修复、正畸正颌、年轻化治疗等提供定量的参考依据。经验证,本研究所采用的基于三维图像的面部测量方法可用以临床面部数字化评估。
[Abstract]:Objective the purpose of this study was to collect and measure the facial data of young adults of Han nationality in northern China by using three-dimensional stereoscopic photography, and to establish the normal value of facial features and to compare the difference of facial morphology between sexes. Methods A total of 100 cases (50 male and 50 female, aged 20 to 29 years old) were recruited for clinical facial digital evaluation with normal range of BMI. VECTRA H1 3D imaging system was used to collect 3D facial images, and 32 linear indexes and 1 angle were measured using 3D images. All the shooting and measurement were performed by the same researcher. Ten 3D images (5 male and 5 female) were measured repeatedly. Intra-group correlation coefficient (ICC) was used to analyze the internal error of the test. Two independent samples were used to compare the difference between male and female, and the paired t-test was used to compare the left face. The right side difference. Results Intra-test error analysis showed that the researchers had a good consistency of measurement for all items and ICC values were 0.800.The facial measurements of men were generally larger than those of women, and there were 16 linear measurements (width of extraocular angle, width of left and right eye fissure, and the width of left and right eye fissure). Intraocular angle width, nasal width, nasal height, nose length, nasal depth, total upper lip height, mouth width, lip peak width, upper lip skin height, morphological face length, face width, lower length, intertragular width, 2 ratios (nasal width / mouth width, Morphologic index) and 7 groups (supraorbital depth, upper 1/3 face depth, lateral canthus-auricular depth, middle 1/3 face depth, angle of mouth-auricular depth, supramental point-auricular depth), facial depth of 7 groups (supraorbital depth, upper 1/3 facial depth, medial 1/3 facial depth, supramental point), There was significant difference between the two sexes (P 0.05). The width of the extraocular corner, nose width, nasal height, nose length, shape face length, face width, bottom length, There was a significant clinical difference between sex (mean difference 3 mm) in the width of auricle and facial depth in 7 groups. Conclusion the normal reference value of facial morphology of Han adults in northern China was established and the differences of facial morphology between men and women were compared. It can provide quantitative reference for facial reconstruction, repair, orthodontic orthognathic and younger treatment, etc. It is proved that the method of facial measurement based on 3D image can be used to evaluate the clinical face digitally.
