Abstract

Background
Understanding the age-related morphological changes of facial soft tissue is fundamental in achieving improved outcomes of rejuvenating procedures. Three-dimensional (3D) photogrammetry is a reliable and convenient anthropometric tool to assess facial soft tissue.
Objective
The aim of this study was to establish age-related facial soft tissue morphology in Korean adult females using non-invasive 3D photogrammetry.
Methods
One hundred and ninety-two female participants were divided into three groups based on age: the younger group (aged 20∼39 years), middle group (40∼59 years), and older group (60∼79 years). Thirty-six landmarks were identified via 3D photogrammetric scanning (Morpheus 3D, Morpheus Co., Ltd., Seongnam, Korea). Fortyone facial dimensions were analyzed using the imaging software to find significance between the age groups.
Results
Smaller upper-facial volume (p=0.019) and shorter upperfacial height (p=0.034) were observed in the older group than in the younger group. In the mid-face, narrowed palpebral fissure (p<0.001) with elongated upper eyelid height (p<0.001) and widened nose (p<0.001) were observed in the older group compared with the younger group. Longer lower-facial height (p<0.001) with longer and wider philtrum (p<0.001, p=0.004, respectively), shorter lower vermilion height (p<0.001), wider mouth width (p<0.001), and smaller lower vermilion angle (p<0.001) were seen in the older group when compared with the younger group. Moreover, greater angles of nasofrontal, nasomental, and labiomental angle (p=0.015, p=0.015, p=0.080, respectively), and smaller nasofacial angle (p=0.034) were observed in the older group than in the younger group.
Conclusion
Our results provide clues of aging-related facial morphological characteristics in Korean female population.
