This procedure depends on technically correct harvesting, separating and re-injection of the fat. Since it always involves removal of fat from areas surroundng the buttocks or other areas of the body, it is done in a sterile operating room environment. You should assure yourself of safety by seeking out a board-certified plastic surgeon. The operation has the usual risks of liposuction, including unnvenness or wa viness of the skin and the risk of infection. In terms of alternatives, patients who want a more shapely buttock, but not necessarily a larger buttock, benefit from liposuction around the buttocks to bring out the desired shape. this means removing fat from the low back, the flanks, waist and hips. For patients who do have adequate fat, I think the use of fat for buttocks augmentatino is preferable to the use of buttocks implants. Very skilled surgeons still sometimes get wound healing problems in the incisions needed to place buttocks implants, and implants can look unnatural, move around, and be affected by fluid collections or seromas even years after implantation. Find a doctor who is skilled at liposuction and well versed in the emerging science of fat transplantation. When fat is treated well and lives in its new location it is a very natural way to augment the buttocks.
