Body sculpture: the words become reality.

The last decade has been marked by the development of liposuction. A better knowledge of the anatomy of fat tissue, together with an improvement in different devices, has made our results more predictable. However, such areas as the chin, anterior and inner thigh, and knee have remained "difficult." This is especially true when large volumes of fat need to be removed. Blood loss has remained a problem as well. The development of ultrasound (U.S.) liposuction is a big step toward even more predictable results and to where blood loss can be negligible.
