Liposuction is a procedure that can help sculpt the body by removing unwanted fat from specific areas, including the abdomen, hips, buttocks, thighs, knees, upper arms, chin, cheeks and neck. During the past decade, liposuction, which is also known as "lipoplasty" or "suction lipectomy," has benefited from several new refinements. Today, a number of new techniques, including ultrasound-assisted lipoplasty (UAL), the tumescent technique, and the super-wet technique, are helping many plastic surgeons to provide selected patients with more precise results and quicker recovery times. Although no type of liposuction is a substitute for dieting and exercise, liposuction can remove stubborn areas of fat that don't respond to traditional weight-loss methods.

The best candidates for liposuction are normal-weight people with firm, elastic skin who have pockets of excess fat in certain areas. You should be physically healthy, psychologically stable and realistic in your expectations. Your age is not a major consideration; however, older patients may have diminished skin elasticity and may not achieve the same results as a younger patient with tighter skin. Liposuction carries greater risk for individuals with medical problems, such as diabetes, significant heart or lung disease, poor blood

Liposuction is a procedure in which localized deposits of fat are removed to recontour one or more areas of the body. Through a tiny incision, a narrow tube or cannula is inserted and used to vacuum the fat layer that lies deep beneath the skin. The cannula is pushed then pulled through the fat layer, breaking up the fat cells and suctioning them out. The suction action is provided by a vacuum pump or a large syringe, depending on Dr. Ratliff's preference. If many sites are being treated, Dr. Ratliff will then move on to the next area, working to keep the incisions as inconspicuous as possible.

Fluid is lost along with the fat, and it's crucial that this fluid be replaced during the procedure to prevent shock. For this reason, patients need to be carefully monitored and receive intravenous fluids during and immediately after surgery.

Though they are rare, complications can and do occur. Risks increase if a greater number of areas are treated at the same time, or if the operative sites are larger in size. Removal of a large amount of fat and fluid may require longer operating times than may be required for smaller operations.

The combination of these factors can create greater hazards for infection; delays in healing; the formation of fat clots or blood clots, which may migrate to the lungs and cause death; excessive fluid loss, which can lead to shock or fluid accumulation that must be drained; friction burns or other damage to the skin or nerves or perforation injury to the vital organs; and unfavorable drug reactions.

There are also points to consider with the newer techniques. For example, in UAL, the heat from the ultrasound device used to liquefy the fat cells may cause injury to the skin or deeper tissues. Also, you should be aware that even though UAL has been performed successfully on several thousand people worldwide, the long-term effects of ultrasound energy on the body are not yet known.

In the tumescent and super-wet techniques, the anesthetic fluid that is injected may cause lidocaine toxicity (if the solution's lidocaine content is too high), or the collection of fluid in the lungs (if too much fluid is administered).

The scars from liposuction are small and strategically placed to be hidden from view. However, imperfections in the final appearance are not uncommon after lipoplasty. The skin surface may be irregular, asymmetric or even "baggy," especially in the older patient. Numbness and pigmentation changes may occur. Sometimes, additional surgery may be recommended.

After surgery, you will likely experience some fluid drainage from the incisions. Occasionally, a small drainage tube may be inserted beneath the skin for a couple of days to prevent fluid build-up. To control swelling and to help your skin better fit its new contours, you may be fitted with a snug elastic garment to wear over the treated area for a few weeks. Dr. Ratliff may also prescribe antibiotics to prevent infection.

Don't expect to look or feel great right after surgery. Even though the newer techniques are believed to reduce some postoperative discomforts, you may still experience some pain, burning, swelling, bleeding and temporary numbness. Pain can be controlled with medications prescribed by Dr. Ratliff, though you may still feel stiff and sore for a few days.

It is normal to feel a bit anxious or depressed in the days or weeks following surgery. However, this feeling will subside as you begin to look and feel better. Healing is a gradual process. Dr. Ratliff will probably tell you to start walking around as soon as possible to reduce swelling and to help prevent blood clots from forming in your legs. You will begin to feel better after about a week or two and you should be back at work within a few days following your surgery. The stitches are removed or dissolve on their own within the first week to 10 days.

Activity that is more strenuous should be avoided for about a month as your body continues to heal. Although most of the bruising and swelling usually disappears within three weeks, some swelling may remain for six months or more.

Dr. Ratliff will schedule follow-up visits to monitor your progress and to see if any additional procedures are needed. If you have any unusual symptoms between visits -- for example, heavy bleeding or a sudden increase in pain -- or any questions about what you can and can't do, call Dr. Ratliff.

You will see a noticeable difference in the shape of your body quite soon after surgery. However, improvement will become even more apparent after about four to six weeks, when most of the swelling has subsided. After about three months, any persistent mild swelling usually disappears and the final contour will be visible.

If your expectations are realistic, you will probably be very pleased with the results of your surgery. You may find that you are more comfortable in a wide variety of clothes and more at ease with your body. And, by eating a healthy diet and getting regular exercise, you can help to maintain your new shape.
