The latest advance in fat aspiration is ultrasonic liposuction, or UAL. Using an ultrasound wave with a frequency of 22,500 Hz (the frequency needed to emulsify the fat cell) the fat can be aspirated without damaging the retaining septa of the skin, arteries, veins and nerves. Using this technique to emulsify and liquefy the fat, large volumes of fat can be aspirated without significant blood loss. Ultrasound is extremely useful for aspirating fat from very difficult zones where the fat is more hardened, such as the upper abdomen and the back.

Not only does ultrasonic liposuction permit fat emulsification and aspiration, but the fat tissue around the treated zone also receives ultrasound waves of lower intensity and can later be remodeled to give shape to the whole area. Ultrasonic liposuction is our first choice because of the advantages it offers: fat can be aspirated from deep planes, retaining septa of the skin are not altered, and a wide area can be remodeled extremely well. Once the ultrasonic liposuction is completed and the volume desired has been removed, we can remodel any localized irregularities and create the desired sculptural shape by working at the surface with a 3 mm cannula.

By combining ultrasonic liposuction and liposculpture in specific areas, we achieve highly satisfactory aesthetic outcomes.

During the postoperative period, lymphatic drainage is very important. We perform at least 10 sessions on alternate days to help to model the treated areas and to reduce the swelling. The patient wears an elastic pressotherapy suit to help the modeling. We strongly recommend physical exercise (for example, stationary cycling without any resistance) and hydrating creams.
