Role of Fat Transfer in Facial Rejuvenation

Abstract

Fat transfer (autologous fat grafting) has increased in popularity for soft tissue augmentation despite perceived drawbacks of unpredictable results. It is considered safe due to the autologous property and fat graft survival duration. Though it is more invasive and expensive than available semipermanent and permanent synthetic fillers, it has least reported complications and longer survivability. The relevant anatomy and pathophysiology is discussed and the clinical applications and techniques as well as possible complications are described.
