Overview of current thoughts on facial volume and aging.

摘要

Facial aging is a dynamic process involving the aging of soft tissue and bony structures. Much is known in regards to how the face loses volume as the soft tissue structures age. Epidermal thinning and the decrease in collagen cause skin to lose its elasticity. Loss of fat, coupled with gravity and muscle pull, leads to wrinkling and the formation of dynamic lines. The aging process has also been shown to affect the facial bones. Multiple studies suggest that the bony aging of the orbit and midface is a process primarily of contraction and morphologic change. This loss of bony volume and projection may contribute to the aged appearance. In this review, we will demonstrate how specific soft tissue and bony aspects of the face change with age in both genders and what impact these structural changes may have on overall facial aesthetics.
