There is the Tumescent technique which is widely used by doctors every where. With the tumescent technique, if the surgeon does not over inject the area with TOO MUCH Lidocaine solution, this technique is proving best. Once upon a time they just shoved the hose in there and sucked away. With the tumescent technique, they engorge the tissues with a saline/Lidocaine solution and suction the fat cells which are not engorged with the solution. This technique also hinders of suctioning out of tissues that are not targeted for removal and lessens bleeding. However, if a surgeon injects too much of the solution the patient can get Lidocaine toxicity which can cause sickness, complications and sometimes death. Although Lidocaine toxicity is most often seen in body sculpture where large amounts of solution in injected within the body and the operation my require a longer period of anesthesia.
There is also a Super-wet technique which is basically like the Tumescent but with not as much solution injected. It breaks down to about the same amount injected as the amount of fat removed.
There is also the Ultra Sonic technique (UAL) which is regularly leaving patents with serious post-operative burns. Apparently the high frequency waves are over-exciting the water particles (or any fluid containing) causing them to boil beneath the skin as well as damaging superficial tissues as well.
And lastly there is the Power-Assisted Liposuction (PAL or MicroAire Technique). PAL is a newer technique where the cannula eases through the fatty tissue (even fibrous) with less trauma than traditional techniques and with no burn risks as with the UAL techniques. This new machine uses a special high-speed "linear reciprocating" suction cannula. You see, with the newer cannula surgeons are able to perform more effective high-volume liposuction in a shorter time, without trauma, especially in more fibrous areas. Fibrous tissue has always been a problem in the buttocks, saddlebags (upper sides of thighs in women), back and the male breast (gynecomastia). The PAL system moves through these areas faster, with less trauma resulting in less work and strain for the surgeon and less pain and a faster recovery in patients.
