Liposculpture / Fat Grafting 

Fat grafting, also referred to as fat transfer or fat injections, is the surgical process by which fat is transferred from one area of the body to another area. The surgical goal is to improve or augment the area where the fat is injected. The technique involves extracting adipose fat by liposuction, processing the fat, and then reinjecting purified fat into the area needing improvement.

Since the 1990's Plastic Surgeons have reliably used fat grafting as a way to improve and enhance the cosmetic appearance of the various areas of the face and body. 

Fat grafting process
The process of fat grafting involves three steps:

extraction of the fat from the donor area with liposuction
decanting, centrifugation, and processing of the fat
reinjection of the purified fat into the area needing improvement
In the first step, fat is extracted from a donor area using liposuction techniques. This is best accomplished by manual methods using thin liposuction cannulas with small holes. Laser or ultrasonic liposuction should not be used for the extraction as it may destroy the fat cells.

The fat is then processed with decanting and centrifugation to separate debris, excess fluid, and dead cells from the viable adipose fat cells. An alternate method is to wash the fat with a sterile saline solution. The fat that is discarded are the fat cells which will likely not survive in the graft and they can even create problems for the good cells.

In the final step, the fat is reinjected in small droplets throughout the subcutaneous tissue of the recipient area. This is to ensure good blood supply to every fat droplet so that the fat graft can survive.

The amount of fat injected is measured in cc's and ultimately varies according to patient case specifics and the area of the body where the processed fat is being injected.
