Fat Grafting from the Buttocks
Fat grafting using fat from the buttocks is a common procedure used to add volume to the face. As people age, the face naturally becomes thinner. The area beneath the eyes may appear hollow or dark because the fat there has diminished. When fat grafting is performed to restore fullness to the face, the fat has to come from somewhere else on the body in a procedure called autologous fat transfer.
The buttocks are an ideal source of fat to be grafted onto other parts of the body. Because the buttocks have a lot of excess fat, the amount needed for facial fat grafting may not be noticeable once removed from the buttocks. In contrast, relatively little fat is needed to make a significant impact on the appearance of the face.
Fat grafting starts with removing fat from the buttocks via liposuction. Tiny incisions are made usually in the crease underneath each buttock so the resulting scars will be discreet. A stainless steel tube called a cannula is inserted through these incisions to extract fat. The fatty tissue is processed to remove free oils, fluids, and blood until the material is virtually all adipose. The fat is then put into syringes and injected into the desired areas.
The patient may experience some swelling and bruising of the buttocks following liposuction. This will diminish in a few days. Most patients can return to work at a desk job in a day or two. The area where the fat is grafted may also be swollen and bruised for several days. If fat was grafted into the face, the patient may wish to stay home until these physical side effects completely subside.
Fat grafting can also be performed on the buttocks to enhance their shape or size. This is the opposite process of liposuction. Fat grafting of the buttocks requires that fat be taken from another fatty area, like the thighs, and placed into the buttocks. The placement of this extra fat underneath the skin can enhance the curve of the buttocks.
Fat grafting of the buttocks can be used to balance out a person’s figure or simply give the buttocks more fullness. Liposuction can remove the crescent-shaped bulge of fat just below the butt on the upper posterior thighs. This fat can then be injected into the top of the buttocks to create a more definitive curvature between the lower back and buttocks.
It is more typical that the fat is removed from the buttocks for fat grafting to other parts of the body.
Fat grafting can be used to add fullness to virtually any part of the body. Some of that fat injected will be absorbed by the body. The surgeon may overfill the area slightly to compensate for this expected absorption. The remaining fat can last up to three years, possibly more, depending on the patient. Fat grafts typically do not last as long in elderly people, people who smoke, and people who exercise very frequently.
