Abstract
Autologous fat transplantation has been performed for almost a century. Only recently, however, has the fat removed by suction been used for correcting certain skin defects as well as for cosmetic enhancement. This paper presents the clinical indications for such a procedure as well as different methods of harvesting the fat intended for transplantation. New techniques and instrumentation intended to facilitate the extraction and injection of fat and make it as atraumatic as possible are described and illustrated. Although survival of the transplanted fat varies, depending on many factors, and has not been fully documented, this procedure is a new and exciting addition to the cosmetic surgeon's armamentarium.
