Dr. Sadati also offers a newer alternative process that uses ultrasonic waves to eliminate difficult fat tissue in the body. Ultrasonic waves help to loosen the difficult fatty layer beneath the skin, so that removal is easier and less invasive. There are several benefits to using this technique, one of them being the fact that it requires a smaller incision. It is usually the best choice for patients who will have a smaller area operated on as it targets smaller, isolated fat pockets in the body. It allows those smaller pockets to be loosened and removed with a smaller device, rather than the large vacuum that is used for the standard liposuction procedure.
