Studies of facial aging up to the present have largely been observational and subjective. This study applies state-of-the-art facial imaging and three-dimensional computer modelling to measure changes in the aging female face. The markers of facial aging discussed here go beyond descriptive accounts by individual practitioners and are presented as quantitative measurements of the volume change in the aging periorbital region.
Three-dimensional image data sets were acquired of 42 mother-daughter matched pairs (83 individuals). Overall similarity of the faces of the mother-daughter pair were confirmed using best fit analyses prior to further processing of the data. The changes in facial structure secondary to aging were measured using volumetric comparisons of periorbital tissues in the daughter and mother. The age range of the individuals imaged range from 15 to 91 years.
A consistent pattern of volume difference and regression of soft tissues associated with the medial canthus nasojugal groove was demonstrated in the aged individual of each pair. The volume difference associated with the tear trough ranged from 0.02cc to 1.27cc with median values of 0.38cc and 0.42cc. Volume differences in the adjacent periorbital tissues are also measured.
Imaging clearly shows a consistent pattern of atrophy and regression of soft tissues associated with the medial canthus and nasojugal groove. Histogram depth analysis of the soft tissue shows greatest atrophy in the medial canthal region and soft tissues caudal to the lower lid. Volumetric analysis of the atrophy of these tissues is a useful adjunct in the accurate rejuvenation of the periorbital region.
迄今为止，关于面部衰老的研究在很大程度上都是观察性和主观性的。本研究应用最先进的面部成像和三维计算机建模技术来测量女性面部衰老的变化。这里讨论的面部衰老标志物超越了个体从业者的描述性描述，并作为衰老眶周区域体积变化的定量测量呈现。
对 42 对母女匹配对（83 人）进行了三维图像数据集采集。在进一步处理数据之前，使用最佳拟合分析确认了母女面部的整体相似性。通过比较女儿和母亲眶周组织的体积变化，测量了由于衰老导致的面部结构的变化。所成像个体的年龄范围从 15 岁到 91 岁。
在每对年龄较大的个体中，都显示出与内眦鼻颊沟相关的软组织体积差异和退行的一致模式。与泪槽相关的体积差异范围从 0.02cc 到 1.27cc，中位数分别为 0.38cc 和 0.42cc。还测量了相邻眶周组织的体积差异。
成像清楚地显示了与内眦和鼻颊沟相关的软组织萎缩和退行的一致模式。软组织的直方图深度分析显示，内眦区域和下眼睑下方的软组织萎缩最大。这些组织萎缩的体积分析是准确年轻化眶周区域的有用辅助手段。
