Many body parts present skin depression or asymmetry due to congenital defects, prior trauma or surgeries. Since most deep and large-area body depressions are difficult to be corrected by nonsurgical methods such as the injection of hyaluronic acid and results last for a very short time, autologous fats convenient for collecting and grafting become the most economic option for filling large-area body depressions. Similar to autologous fat breast augmentation, this surgery needs to first purify and filtrate adipocytes collected by liposuction from abdomen or thighs, and then mix them with growth factors before injecting them into the sunken site at a proper volume. Nevertheless, because the self-absorption rate greatly varies along with the activity patterns of different parts, secondary fat grafting may be needed to achieve satisfactory results.

Apart from addressing body surface defects, autologous fats are used to improve or enhance the body curvature or for other simple esthetic purposes, such as buttock augmentation, pectoral reshaping, muscular texture modification (such as hand desquamation or knee or calf curvature), sculpting six packs in combination with ultrasonic high-definition muscular etching or even revision of skin sinking due to a prior improper liposuction. Because its clinical applications are quite extensive and flexible, patients need to thoroughly discuss with Dr. Chuang in making their surgical plans.
