Abstract
Fat grafting is one of the most useful tools for the plastic surgeon, since it has been described as having most of the characteristics of the ideal filler. However, it is not exempt of complications or drawbacks: loss of volume, fat necrosis, and infection are some of the most common problems of fat grafting.
The loss of volume is evidently the most frustrating problem faced with fat grafting, since adipocytes are highly fragile cells with very short lives that cannot tolerate excessive manipulation. The process of fat grafting, as in skin grafts, relies on different variables such as donor-site election, harvesting, processing, and injection techniques. Each step involves several variables that might influence the survival of the graft and will be discussed in this chapter.
We will discuss the current knowledge on fat integration and remodeling. We also will review the available literature on the different variables that can impair the survival of the fatty graft, such as the effect of the donor site, methods of harvesting, and different processing techniques, including newer technologies.
