The surgery
The time required to perform liposuction may vary considerably, depending
on the size of the area, the amount of fat being removed, the type of anesthesia
and the technique used.
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.
Technique variations
The basic technique of liposuction, as described above, is used in all
patients undergoing this procedure. However, as the procedure has been developed
and refined, several variations have been introduced.
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.
All surgery carries some uncertainty and risk
Liposuction is normally safe, as long as patients are carefully selected,
the operating facility is properly equipped and the physician is adequately
trained.
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.
After your surgery
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. Your
doctor 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 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.
Getting back to normal
Healing is a gradual process. Your surgeon 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.
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.
Your new look
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.

As healing progresses, a more proportional
look will emerge.

A slimmer body contour can help you feel
more confident and comfortable.
