The most significant is that the operation can be used to remove large volumes of fat.
Traditional liposuction is used for sculpturing smaller volumes.
In ultrasonic liposuction there is less capillary tearing and therefore much less blood loss. In traditional liposuction the skin contracts very little. Ultrasonic liposuction may cause skin contraction and retraction especially in areas like the neck. In the early stages and with the two stage method of ultrasonic liposuction the process may take longer. It is expected that as surgeons become more experienced and the equipment better it will take less time.
