Ultrasonic Sound Waves Liquefy Fat
During ultrasonic liposuction, fat removal is initiated by sound waves produced by a generator. The ultrasonic waves are transmitted to a thin, vacuum-like tube, called a cannula. When the cannula comes into contact with the fat cells, they quickly liquefy, and are easily vacuumed out.
Ultrasonic Liposuction Risks
Because a large amount of heat is created during ultrasonic liposuction, there is a greater risk of burns, blistering, and scarring. A UAL surgeon with liposuction experience will know how to avoid this problem, but the danger should still be noted. Another risk is a condition called seroma, which occurs when the body tries to fill the void created by fat removal by producing excess fluid. This fluid must be removed continuously with a syringe until the cavity has closed. After ultrasonic liposuction, side effects such as bruising, swelling, and discomfort are common.
