The best candidates
for liposuction
To be a good candidate for liposuction, you must have realistic
expectations about what the procedure can do for you. It's important
to understand that liposuction can enhance your appearance and self
confidence, but it won't necessarily change your looks to match your
ideal or cause other people to treat you differently. Before you
decide to have surgery, think carefully about your expectations and
discuss them with your surgeon.
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.
Planning your
surgery
In your initial consultation, your surgeon will evaluate your health,
determine where your fat deposits lie and assess the condition of your
skin. Your surgeon will explain the body-contouring methods that may
be most appropriate for you. For example, if you believe you want
liposuction in the abdominal area, you may learn that an
abdominoplasty or "tummy tuck" may more effectively meet
your goals; or that a combination of traditional liposuction and UAL
would be the best choice for you.
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.
Preparing for your
surgery
Your surgeon will give you specific instructions on how to prepare for
surgery, including guidelines on eating and drinking, smoking, and
taking or avoiding vitamins, iron tablets and certain medications. If
you develop a cold or an infection of any kind, especially a skin
infection, your surgery may have to be postponed.
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.
Anesthesia for
liposuction
Various types of anesthesia can be used for liposuction procedures.
Together, you and your surgeon will select the type of anesthesia that
provides the most safe and effective level of comfort for your
surgery.
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.
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.
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.
