Two basic types are used in liposuction – the Tumescent technique and Ultrasonic liposuction. On the whole, they have several similarities but are different in some important points. Both types of liposuction consist of similar surgical elements, and if you use ultrasound liposuction, you have to include tumescent as well.
The tumescent type of liposuction is known under many names: standard liposuction, lipoplasty, liposculpture, or suction-assisted lipoplasty. In was first practiced in the USA in the year 1982. The method is as follows: first, the fat is infiltrated with tumescent fluid, which contains saline saluted with local anaesthetic. After being filled up with the fluid, the fat is pulled out with tiny rods or by making small incisions. Scars are hidden with natural skin creases. Tumescent method alleviates pain, as it contains anaesthetic, and reduces blood loss.
Ultrasonic is the other type of liposuction and it also starts with injecting tumescent fluid to make the fat stiff. But from that point the two types differ: with ultrasonic, the fat is liquefied by high-frequency ultrasonic energy, emitted from a thin rod, and then is taken out of the body using the rod as a tiny pipette.
These two types of liposuction have several derivative types that are getting extremely popular as they combine the strong points of the basic types. With the further development of higher technologies we are surely to be encountered with new and modern types of liposuction in the years to come.
Suction-Assisted Liposuction: This is the combinative usage of tiny cannula inserted into the fat area by small incisions. A pressure is exercised over the place in order to drag the fat out.
Another type of liposuction is called Ultrasound-Assisted Liposuction. From the top of the cannula are emitted ultrasound waves that liquefy the fat before sucking it out.
External Ultrasound-assisted Liposuction. This type of liposuction uses ultrasound waves that carry out the procedure by changing the structure of the fat cells. Then a tumescent fluid is injected to transmit the external waves and the fat is taken out.
Power-assisted Liposuction is a type of liposuction that takes the fat out by producing gentle pushes into and out of the skin. The tip of a cannula is the best instrument for doing this. The fat is gradually pulled out after several attempts.
VASER-assisted Liposuction: the last type of liposuction is the most high-tech developed. It uses constant stream of ultrasonic energy being inflicted on the fat area. The fat sells are broken up by the ultrasound waves pressure and then taken out by suction.
