What is the difference between ultrasound-assisted liposuction (UAL) and regular liposuction?
The ultrasound technique uses sound waves to cause the fat cells to burst, liquefy as an oil, and mix with the wetting fluid. Proponents of the technique believe that the fat can then be more easily suctioned. The advantages of the technique are not agreed on by all plastic surgeons. UAL is slower than super–wet liposuction and, because of the high energy sound waves employed, there is an increased danger of burning the skin and of nerve damage. Ultrasound equipment is expensive and the cost is normally passed on to the patient. However, ultrasound may have an advantage in breaking up fat in fibrous areas that are more difficult to treat with traditional liposuction.
