Liposuction

Definition:

Liposuction is the removal of excess body fat by suction with specialized surgical equipment, typically performed by a plastic surgeon.

Alternative Names:
Fat removal - suctioning
Description:

Liposuction has achieved the distinction of being the most popular cosmetic surgical procedure. By removing unwanted deposits of excess fat, liposuction improves body appearance and smoothes irregular or distorted body shapes. The procedure is sometimes referred to as body contouring.

Liposuction may be useful for contouring under the chin, neck, cheeks, upper arms, breasts, abdomen, buttocks, hips, thighs, knees, calves, and ankle areas.

However, liposuction is a serious surgical procedure and possibly may involve a painful recovery. It has the potential for rare but serious or occasionally fatal complications, so the decision to have liposuction should be well thought out.

Before undergoing liposuction certain criteria must be met:

An initial patient consultation. This will include a history, a thorough physical examination, and a psychological health examination.
Your spouse's presence may be required during the visit and a second consultation is necessary to give you time to think over the surgery.
You should feel free to express the reasons for the consult, be free to ask as many questions as desired, and feel satisfied with the answers to those questions. A properly informed person makes a better patient.
You must understand fully the pre-operative preparations, the liposuction procedure, and the precise post-operative care.
You must have realistic expectations. Liposuction may help to enhance your appearance and also your self-confidence, but it will probably not give you your ideal body.

There are several different liposuction procedures.

Tumescent liposuction (fluid injection) is the most common type of liposuction. It involves injecting a large amount of medicated solution into the areas before the fat is removed (sometimes, up to three times the volume of fat to be removed). The fluid is a mixture of local anesthetic (lidocaine), a drug that contracts the blood vessels (epinephrine), and an intravenous (IV) salt solution. The lidocaine in the mixture helps to numb the area during and after surgery, and may be the only anesthesia needed for the procedure. The epinephrine in the solution helps to reduce the loss of blood, reduce the amount of bruising, and reduce the amount of swelling that accompanies the surgery. The IV solution helps to remove the fat more easily and is suctioned out along with the fat. This type of liposuction generally takes longer than other types.

The super-wet technique is similar to the tumescent liposuction stated above. The difference is that not as much fluid is used during the surgery--the amount of fluid injected is equal to the amount of fat to be removed. This technique takes less time; however it often requires sedation via an IV, or general anesthesia.

Ultrasound-assisted liposuction (UAL) is a fairly new technique, used in the US since 1996. During this technique ultrasonic vibrations are used to liquefy fat cells. After the cells are liquefied, they can be vacuumed out. UAL can be done in two ways, external (above the surface of the skin with a special emitter) or internal (below the surface of the skin with a small, heated cannula). This technique may help to remove fat from dense, fibrous areas of the body such as the upper back or enlarged male breast tissue. UAL is often used in combination with the tumescent technique, in secondary (follow-up) procedures, or when precision must be enhanced. In general this procedure takes longer than the super-wet technique.
