subject: Various Techniques Used In Liposuction Procedures [print this page] Since its beginnings as a simple fat-removal procedure in the 1970s, liposuction has become very popular. In fact, walking down the streets of New York, one would most assuredly cross paths with several people who have successfully undergone liposuction procedures. There are several different techniques used today to remove unwanted fat cells. The type of technique used depends on the surgeon and the area treated. These techniques include tumescent, dry, wet, super wet, ultrasonic (UAL), power assisted (PAL), and laser assisted lipolysis (LAL).
In general, liposuction involves removing fat cells with a hollow tube called a cannula and a suction device called an aspirator. A small incision is made near the area to be treated large enough for the cannula to fit. The fat cells are then suctioned out permanently, the incision closed, and the patient allowed to recover and enjoy final results after a few months.
The tumescent technique was one of the first techniques used for liposuction. It involves the injection of large amounts of local anesthetic (such as lidocaine). The procedure can then be done with only intraveneous sedation rather than general anesthesia.
The dry technique is done without the injection of any fluids, hence the name. This technique is rarely used today.
The wet technique requires the injection of a small amount of fluid (less volume than the amount of fat to be removed). The fluid injected includes the local anesthetic lidocaine, adrenaline, and a saline solution. The combination of these fluids loosens the fat cells, making it easier to suction the fat cells. It also reduces the chances of bruising.
The super wet technique uses about half the volume of local anesthetic as the tumescent technique (about the same volume as the amount of fat to be removed). This is the most-utilized technique for the removal of large amounts of fat. It may require IV sedation, as well as local or complete anesthetic.
Ultrasonic Assisted Liposuction (UAL) uses ultrasonic vibrations to emulsify (liquefy) fat cells before their removal. The liquid fat cells are then suctioned, just as in other procedures.
Power Assisted Liposuction (PAL) involves a special mechanized cannula and the use of tumescent fluid. The cannula uses small, rapid vibrations to break up fat cells before they are suctioned. PAL is considered a more gentle technique, as surgeons do not have to use as much force when removing fat cells.
Laser Assisted Lipolysis (LAL) also involves the use of tumescent fluid and a specialized cannula. A smaller incision is made in order to insert a microcannula, which is inserted to deliver laser energy and heat to break up fat cells.
