Liposuction

Liposuction is a minimally invasive cosmetic procedure that uses a thin, hollow tube called a cannula to remove localized areas of body fat. The cannula is inserted through extremely small incisions and then moved back and forth to loosen excess fat, which is suctioned out using a vacuum or a cannula-attached syringe. Treated areas look slimmer, more contoured, and in better overall proportion to the rest of the body. However, liposuction is not a method for losing weight and is not effective in eliminating cellulite or tightening loose and sagging skin.

The ideal candidate for liposuction is in good overall health but has one or more areas of fat that do not respond to diet or exercise. Areas that are often treated with liposuction include the thighs, abdomen, arms, back, hips, buttocks, chest, face, calves, and ankles. Liposuction can be performed alone or in conjunction with other cosmetic procedures, such as thighplasty (thigh lift) and abdominoplasty (tummy tuck).

The Liposuction Procedure

One of the most common liposuction techniques is tumescent liposuction, which may be assisted by ultrasound or laser-assisted techniques. It is performed on an outpatient basis.

During tumescent liposuction, a solution comprising saline solution, lidocaine (an anesthetic), and epinephrine (a blood vessel contractor) is injected into the area being treated. The solution causes the targeted tissue to swell and become firm, which makes it easier to remove via the cannula. The advantages of this technique are that the anesthetic is built in, so there is no need for general or IV sedation, and blood loss is minimized because the epinephrine constricts the blood vessels.

In laser-assisted tumescent liposuction, a laser is used to liquefy the fat, which makes removing it easier. The laser can also be used to tighten treatment-area skin after the fat is removed. Similarly, ultrasound-assisted liposuction works by using ultrasound energy to liquefy fat.

Recovery From Liposuction

After liposuction, patients experience mild swelling, bruising, and discomfort in the treated area. Compression garments or elastic bandages are typically worn to help reduce these symptoms as the area heals. Patients can return to work and other regular activities as soon as they feel comfortable, which is usually after a few days. Exercise and other strenuous activities should be avoided for a few weeks.

Risks of Liposuction

In addition to the usual risks associated with surgery, risks associated with liposuction include the following:

• Loose or rippled skin
• More visible cellulite
• Asymmetry
• Contour irregularities
• Pigmentation irregularities

When large amounts of fat are removed, surgery to remove excess skin may also be necessary.

Results of Liposuction

The results of the liposuction procedure may not be apparent until the swelling and bruising subside, which usually takes a week; residual swelling should completely resolve within a few months. Because the incisions used for the cannula are so small, incisions are rarely sutured, and scarring is almost nonexistent. The results of liposuction are typically long-lasting. The fat cells are permanently removed, but future weight fluctuations may cause the remaining cells to enlarge or shrink in response.
