If you're considering liposuction, this page will give you a basic understanding of the procedure — when it can help, how it is performed and how you might look and feel after surgery. It won't answer all of your questions, since much depends on your individual circumstances. Please ask your doctor if there is anything about the procedure you don't understand.
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 circulation, or those who have recently had surgery near the area to be contoured.
Women may have liposuction performed under the chin, on their hips, thighs, and stomach, and in the under arm and breast area.
Be frank in discussing your expectations with your surgeon. He or she should be equally frank with you, describing the procedure in detail and explaining its risks and limitations.
For men, common sites include under the chin and around the waist. Liposuction may also be used in the reduction of enlarged male breasts, a condition known as gynecomastia.
Your surgeon's education and training have helped to form his or her surgical judgement, so take the time to do some background checking. Patients are encouraged to consider a doctor certified by the American Board of Plastic Surgery ("ABPS"). By choosing a plastic surgeon who is certified by the ABPS, a patient can be assured that the doctor has graduated from an accredited medical school and completed at least five years of additional residency - usually three years of general surgery (or its equivalent) and two years of plastic surgery. To be certified by the ABPS, a doctor must also practice surgery for two years and pass comprehensive written and oral exams.
Though it is rarely necessary, your doctor may recommend that you have blood drawn ahead of time in case it is needed during surgery.
Also, while you are making preparations, be sure to arrange for someone to drive you home after the procedure and, if needed, to help you at home for a day or two.
If only a small amount of fat and a limited number of body sites are involved, liposuction can be performed under local anesthesia, which numbs only the affected areas. However, if you prefer, the local is usually used along with intravenous sedation to keep you more relaxed during the procedure. Regional anesthesia can be a good choice for more extensive procedures. One type of regional anesthesia is the epidural block, the same type of anesthesia commonly used in childbirth.
However, some patients prefer general anesthesia, particularly if a large volume of fat is being removed. If this is the case, a nurse anesthetist or anesthesiologist will be called in to make sure you are completely asleep during the procedure.
There are several liposuction techniques that can be used to improve the ease of the procedure and to enhance outcome.
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 the surgeon's preference. If many sites are being treated, your surgeon 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.
Fluid Injection, a technique in which a medicated solution is injected into fatty areas before the fat is removed, is commonly used by plastic surgeons today. The fluid — a mixture of intravenous salt solution, lidocaine (a local anesthetic) and epinephrine (a drug that contracts blood vessels) — helps the fat be removed more easily, reduces blood loss and provides anesthesia during and after surgery. Fluid injection also helps to reduce the amount of bruising after surgery.
The amount of fluid that is injected varies depending on the preference of the surgeon.
Large volumes of fluid — sometimes as much as three times the amount of fat to be removed — are injected in the tumescent technique. Tumescent liposuction, typically performed on patients who need only a local anesthetic, usually takes significantly longer than traditional liposuction (sometimes as long as 4 to 5 hours). However, because the injected fluid contains an adequate amount of anesthetic, additional anesthesia may not be necessary. The name of this technique refers to the swollen and firm or "tumesced" state of the fatty tissues when they are filled with solution.
The super-wet technique is similar to the tumescent technique, except that lesser amounts of fluid are used. Usually the amount of fluid injected is equal to the amount of fat to be removed. This technique often requires IV sedation or general anesthesia and typically takes one to two hours of surgery time.
Ultrasound-Assisted Lipoplasty (UAL). This technique requires the use of a special cannula that produces ultrasonic energy. As it passes through the areas of fat, the energy explodes the walls of the fat cells, liquefying the fat. The fat is then removed with the traditional liposuction technique.
UAL has been shown to improve the ease and effectiveness of liposuction in fibrous areas of the body, such as the upper back or the enlarged male breast. It is also commonly used in secondary procedures, when enhanced precision is needed. In general, UAL takes longer to perform than traditional liposuction.
As a minimum, your surgeon should have basic (core) accredited surgical training with special training in body contouring. Also, even though many body-contouring procedures are performed outside the hospital setting, be certain that your surgeon has been granted privileges to perform liposuction at an accredited hospital.
Your doctor must have advanced surgical skills to perform procedures that involve the removal of a large amount of fat (more than 5 liters or 5,000 ccs); ask your doctor about his or her other patients who have had similar procedures and what their results were. Also, more extensive liposuction procedures require attentive after-care. Find out how your surgeon plans to monitor your condition closely after the procedure.
However, it's important to keep in mind that even though a well-trained surgeon and a state-of-the art facility can improve your chance of having a good result, there are no guarantees. 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.
Improvement will become apparent after about six weeks, when most of the swelling has subsided.
Don't expect to look or feel great right after surgery. Even though the newer techniques are believed to reduce some post-operative discomforts, you may still experience some pain, burning, swelling, bleeding and temporary numbness. Pain can be controlled with medications prescribed by your surgeon, 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.
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.
Your surgeon 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 your doctor.
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.
