Fat transfer to buttocks has become very popular. The procedure works very well and the out come is permanent. However you can expect ~ 30 % loss in fat survival. The procedure is performed as out-patient usually under general anesthesia. The main concern here is the amount of fat available. A typical procedure involves liposuction of multiple areas to obtain enough fat to get the desired result. Under normal circumstance abdomen alone does not contain enough donor fat, therefore liposuction of other areas are also considered, such as hips and thighs. The harvested fat must be strained and sometimes washed with sterile antibiotic solution for best result. Activities after surgery are also restricted to allow for maximum fat survival.
