The purpose of this research is to evaluate how well the filling effect of the fat remains over time. A person's own fat may be used to improve the appearance of the body by moving it from an area where it is less needed. This is called fat grafting, and it is a common procedure, performed approximately 65,000 times by plastic surgeons in the United State last year. The fat is usually taken from the thighs or abdomen with a small liposuction tube and then moved to an area that has lost volume or fullness due to aging, trauma, surgery, birth defects, or other causes. Typically, the transferred fat results in an increase in volume of the body site being treated.
