Facial lifting and volume restoration are the major strategies of facial rejuvenation, but the aging of facial soft tissues has not been sufficiently explored.
This study aimed to reveal the age-related changes in full facial soft tissue of Han Chinese by using computed tomography.
The measurements were performed on head computed tomographic images of 200 Han Chinese subjects (100 men and 100 women). The thickness of facial soft tissue was measured at 20 anthropological landmarks of the skull.
The thickness at rhinion was increased, whereas the thickness at midphiltrum, supradentale, and infradentale was decreased, indicating the significant differences in both sexes. Besides, the thickness at glabella, nasion, supramentale, and menton was decreased significantly in women. The thickness at supraorbital and lateral orbit was increased with aging in either sex. The thickness at frontal eminence, infraorbital, supraglenoid, and gonion showed significant age-related increases in women, and the thickness at zygomatic arch, supra M2, and infra M2 was significantly decreased in men.
These results suggest that soft tissues in different areas of the face are selectively thickened or thinned with aging, thus providing a reference for rejuvenation procedures.
面部提升和体积重塑是面部年轻化的主要策略，但面部软组织的衰老尚未得到充分探讨。
本研究旨在通过计算机断层扫描（CT）揭示汉族人全颜面软组织的年龄相关性变化。
对 200 例汉族受试者（男、女各 100 例）的头部 CT 图像进行了测量。在颅骨的 20 个人体测量标志点测量了面部软组织的厚度。
鼻尖处的厚度增加，人中、上唇龈点和下唇龈点处的厚度减少，男女两性之间存在显著差异。此外，女性的眉间、鼻根、上唇龈点和颏点的厚度显著减少。眶上和眶外侧的厚度随年龄增长而增加，无论性别如何。女性的额突、眶下、颧弓下和下颌角处的厚度与年龄呈显著正相关，男性的颧弓、上颌第二磨牙上方和下方的厚度显著减少。
这些结果表明，面部不同区域的软组织随年龄增长选择性地增厚或变薄，为年轻化手术提供了参考。
