Since liposuction was first developed in the 70's, there have been a number of different procedures developed in attempts to improve the efficacy of the surgery. Some of these techniques have greatly increased the results and safety of the procedure. Others have been found to be problematic or even dangerous. This article will explain ultrasonic liposuction, a procedure which continues to be debated.

Ultrasonic liposuction (also called ultrasonic assisted liposuction, or UAL) was developed in the late 80's. The concept of using ultrasonic sound waves to break down fat during the process of liposuction first originated in Europe. Surgeons got the idea that the vibrations caused by ultra high pitch sound waves could help to shake loose fat and ease in the liposuction process. The surgery spread in Europe and Latin America before making its way into the United States.

Ultrasonic liposuction breaks down into two categories: internal and external. In internal ultrasonic liposuction, the cannula itself (the hollow needle which is used for the fat suction) emits the ultrasonic vibrations. In external, the ultrasonic waves are emitted by a device outside the body. Most ultrasonic liposuction performed today is internal.

Experts remain divided as to the efficacy and safety of UAL. Although some surgeons remain firmly convinced on the side of UAL, many experts believe that UAL is more dangerous than other forms of liposuction. One of the main dangers cited by scientists is the possibility of serious burns. The ultrasonic waves heat the patient's tissue, and if a surgeon is not careful, burns can result. Some studies also suggest that the heat produced by UAL can lead to blood clots.

UAL can also lead to nerve damage. Some research suggests that patients of UAL experience a greater amount of numbness than patients of other types of liposuction. This information has made some scientists caution against using UAL on the face, neck, legs and arms, which have a large supply of vulnerable nerves.

UAL can also lead to the creation of pockets of clear fluid, called seromas. These seromas sometime drain on their own, but they sometimes require additional surgery in order to drain them.

External UAL devices should never be used over the heart or large arteries. They should similarly not be used near the ovaries, as they could lead to serious health issues.

The decision of what type of liposuction you get is up to you, but it is important to do enough research to know possible risks beforehand.
