As of Dec. 2011, I'm one of the first U.S. centers to offer the Liposonix, the first FDA approved fat melting device. It is FDA approved on the abdomen and flanks but has been used off-label on many other parts of the body. It uses high-intensity focused ultrasound to cause lysis or destruction of the fat cells. There is no other device that can make this claim in the U.S. It is nonsurgical liposuction, a revolutionary technologic breakthrough. It is not a replacement for liposuction because you cannot remove the high volumes of fat possible thru liposuction but you can get about an inch reduction (2.5 cm) in fat per treatment per area. It has been used on thighs, buttocks, hips, flanks, back. It can be extremely painful in the inner thighs if there's not enough fat--adjustments can be made with settings and number of passes to treat that area. There are many treatment techniques that can be applied towards treating off-label regions and that's where the skill level and experience of the surgeon is extremely important.
