Fat transfer, is the process of using the patient's own fat to increase the volume of fat in another area of their body. The fat is harvested or extracted with a liposuction cannula. They are prepared for reintroduction into the body and injected into the new part of the body where the additional bulk is used for medical or cosmetic purposes. The most common donor areas, where fat is taken from, are the stomach, thighs, and waist.
The procedure is minimally invasive making it very appealing. Another advantage of fat transfer is that the body does not reject it because it is the patient's own fat. However, there is a rate of absorption, a percentage of the transferred fat, that does not survive. Therefore, it is extremely important to select a surgeon that uses a proven technique with the highest fat survival rate.
