The Anatomy of Suborbicularis Fat: Implications for Periorbital Rejuvenation

This anatomy helps to define midface adipose tissue as a system of superficial and deep fat, of which medial and lateral sub-orbicularis oculi fat are a part. A working hypothesis of facial aging continues with the concept that loss and/or ptosis of deep fat compartments leads to changes in shape and contour. Folds, in contrast, occur at transition points between thick and thinner superficial fat compartments. These anatomical observations further the goal of site-specific augmentation and facial rejuvenation.
