Lasers
in Plastic Surgery
If you're considering laser resurfacing ...
In
laser resurfacing, sometimes called "laser peel,"
a carbon dioxide (CO2) laser is used to remove areas of
damaged or wrinkled skin, layer by layer. The procedure
is most commonly used to minimize the appearance of fine
lines, especially around the mouth and the eyes. However,
it is also effective in treating facial scars or areas
of uneven pigmentation. Laser resurfacing may be performed
on the whole face or in specific regions. Often, the procedure
is done in conjunction with another cosmetic operation,
such as a facelift or eyelid surgery.
Laser
resurfacing is still a very new procedure. However, it
has been shown that in some cases, this surgical method
produces less bleeding, bruising and post-operative discomfort
than is typically seen with other resurfacing methods.
This
brochure will give you a basic understanding of the laser
resurfacing procedure - when it can help, how it's performed
and what results you can expect. It cannot, however, provide
all the details which may be relevant to your particular
needs. Please ask your plastic surgeon if there is anything
about the procedure you don't understand.
A
word about the laser
Laser resurfacing is performed using a beam of laser energy
which vaporizes the upper layers of damaged skin at specific
and controlled levels of penetration.
It's
clear that laser resurfacing may offer a number of advantages
over other resurfacing methods: precision, little (if
any) bleeding and less post-operative discomfort. However,
laser resurfacing isn't for everyone. In some cases, an
alternative skin resurfacing treatment, such as dermabrasion
or chemical peel, may still be a better choice.
All
resurfacing treatments work essentially the same way.
First, the outer layers of damaged skin are stripped away.
Then, as new cells form during the healing process, a
smoother, tighter, younger-looking skin surface appears.
Laser resurfacing is a new method being used by plastic
surgeons to remove damaged skin. Because it is new, there
are no long-term data on this technique. However, a number
of studies using microscopic examination have shown that
the physical changes that occur to laser-treated skin
are essentially identical to those that occur with either
dermabrasion or chemical peel. Ask your plastic surgeon
about the latest facts concerning long-term follow-up.
For
superficial or medium resurfacing, the laser can be limited
to the epidermis and papillary dermis. For deeper resurfacing,
the upper levels of the reticulas dermis can also be removed.
Varied penetration allows treatment of specific spots
or wrinkles.
It's
also important to consider the length of recovery when
choosing among the skin-resurfacing alternatives. In general,
the more aggressive the resurfacing procedure is, the
more prolonged the recovery is likely to be. "Light"
resurfacing procedures, such as superficial chemical peels
or superficial laser resurfacing, offer shorter recovery
times. However, these lighter procedures may need to be
repeated multiple times to achieve results comparable
to those achieved with more aggressive techniques.
The
best candidates for laser resurfacing
In many cases, facial wrinkles form in localized areas,
such as near the eyes or around the mouth. The laser can
be precisely controlled so that only these specific areas
are targeted.
Men and women of all ages can benefit
from laser resurfacing. The ideal patient
for laser resurfacing has fair, healthy,
non-oily skin.
When healing is complete, the face
has a more youthful appearance.
Patients with olive skin, brown skin or black skin may
be at increased risk for pigmentation changes no matter
what type of resurfacing method is recommended. Your plastic
surgeon will evaluate your skin characteristics and make
recommendations accordingly.
Also,
individuals who have taken accutane in the past 12-18
months or are prone to abnormal (keloid-like) scarring
or those with active skin infections on the treatment
area may not be appropriate candidates for this procedure.
Remember,
having laser resurfacing can help enhance your appearance
and your self-confidence, but it won't completely remove
all facial flaws or prevent you from aging. Lines that
occur as a result of natural movements of the face - smiling,
squinting, blinking, talking, chewing - will inevitably
recur. Your plastic surgeon can suggest ways to help you
preserve your results by protecting yourself from sun
exposure or using maintenance treatments, such as light
chemical peels or medicated facial creams. Before you
decide to have laser resurfacing, think carefully about
your expectations and discuss them with your surgeon.
All
surgery carries some uncertainty and risk
When laser resurfacing is performed by a qualified, experienced
surgeon, complications are infrequent and usually minor.
However, because individuals vary greatly in their anatomy,
their physical reactions and their healing abilities,
the outcome is never completely predictable.
Risks
associated with laser resurfacing include: burns or other
injuries from the heat of the laser energy, scarring,
and obvious lightening or darkening of the treated skin.
Also, laser resurfacing can activate herpes virus infections
("cold sores") and, rarely, other types of infection.
Additional
corrective measures and treatment may be required if healing
seems abnormal or delayed or if there is any evidence
of abnormal pigmentation or scarring.
You
can reduce your risks by choosing a qualified plastic
surgeon who has received special training in laser surgery.
Planning
your surgery
Not every practitioner who offers laser surgery has the
same level of experience and skill with laser use. That
is why it is especially important that you find a plastic
surgeon who is adequately trained in the procedure.
One
safety measure is to find out whether your surgeon has
privileges to perform laser resurfacing with a CO2 laser
at an accredited hospital. Even if the operation is to
be conducted in your doctor's private facility, the fact
that he or she has privileges to use that same laser in
a hospital ensures that the doctor has been reviewed by
the institution's experts.
In
your initial consultation, be frank in discussing your
expectations with the surgeon and don't hesitate to ask
any questions you may have. Your surgeon should be equally
frank with you, explaining the factors that could influence
the procedure and the results - such as any abnormal skin
condition which has been diagnosed or previously treated,
medications you are taking or have taken in the past,
previous skin injuries or previous operations.
Your
surgeon will discuss your medical history, perform a routine
examination and photograph the area to be treated. He
or she should explain the procedure in detail, along with
its risks and benefits, the recovery period and the costs.
Remember,
cosmetic laser treatments can be expensive and are usually
not covered by medical insurance. On rare occasions, the
procedure can be used for modification of scars or the
removal of pre-cancerous skin growths. These conditions
could meet the criteria for "medical necessity,"
usually required by insurance companies before coverage
will be provided. Your plastic surgeon can advise you
how to contact your insurance carrier to determine whether
benefits will be allowed in such instances.
Fine, vertical creases or "lipstick lines"
are commonly treated with laser
resurfacing.
Within about five weeks after treatment,
the upper lip is noticeably smoother.
Preparing for the laser procedure
Depending on your individual needs, your surgeon may recommend
that you begin a pre-treatment plan to prepare the skin
for resurfacing.
At
the time of the procedure, you will be given specific
instructions on how to care for your skin immediately
following your laser treatment. Your surgeon may also
instruct you to follow a specific maintenance regimen
for long-term care of the skin to maximize the benefits
of the procedure.
While
you are making plans, be sure to make arrangements for
someone to drive you home if you will be given tranquilizers
or sedation for your laser treatment.
Where
your laser treatment will be performed
Laser resurfacing may be performed in a hospital, an outpatient
surgery center or a surgeon's office-based facility. For
cost containment and convenience, laser resurfacing is
usually done on an outpatient basis. For the more extensive
resurfacing procedures or for resurfacing combined with
other surgical procedures, you may be admitted to a hospital
or a recovery center.
Types
of anesthesia
Laser resurfacing is most commonly performed under local
anesthesia with sedation, especially when it's used to
treat localized areas of the face. You'll be awake but
relaxed, and will feel minimal discomfort. For more extensive
resurfacing, your surgeon may prefer to use general anesthesia,
in which case you'll sleep through the procedure.
The
procedure
Laser resurfacing is a relatively quick procedure. It
usually takes anywhere from a few minutes to 1 1/2 hours,
depending on how large of an area is involved.
When
the imperfections are especially deep, your surgeon may
recommend that the resurfacing be performed in two or
more stages.
During
the procedure, the activated laser is carefully passed
back and forth over the skin until the surgeon reaches
the level that will make the wrinkle or scar less visible.
When
the procedure is over, your surgeon may choose to treat
the resurfaced skin with applications of protective creams
or ointments until healing is complete. Some surgeons
choose to apply a bandage over the treated areas which
will cover and protect the healing skin for the first
five to ten days.
After
your treatment
You are likely to experience some mild swelling and discomfort
after laser resurfacing. However, this can be controlled
with ice packs and medications prescribed by your surgeon.
If
a bandage was applied after your procedure, it may be
replaced with a fresh one after a day or two. After about
a week or so, your bandage will be removed and a thin
layer of ointment may be applied to the skin. Once this
stage is reached, your surgeon will provide instructions
on how to gently wash and care for your healing skin.
During
this phase of healing, it is very important that you not
pick the crusts off the treated area or scarring may result.
Most patients are free of crusts by about 10 days post-operatively.
Redness may persist for several weeks.
Getting
back to normal
Your new skin will usually remain bright pink to red in
the weeks following the procedure. Your surgeon may prescribe
medications to make this color subside more rapidly. After
about two weeks or so, most patients can safely apply
makeup to conceal this temporary color change. However,
some pinkness may remain for up to six months.
It
is rare, some patients may find that their healing skin
is unusually sensitive to the makeup that was regularly
used prior to treatment. In such instances, makeup should
be avoided until a substitute can be found or until the
healing progresses to a point at which the makeup no longer
causes a reaction.
Above
all, in the months following treatment, it's important
to protect the treated area from the sun until all the
color has returned to normal. Using sun protection regularly
will help to maintain your results and reduce the chance
of any new sun damage to your skin.
If
you must be in the sun, apply a strong sun block with
an SPF of 15 or higher and shade your face with a hat
or visor. If resurfacing was performed around the eyes,
it's best to also wear good quality sunglasses with UVA
and UVB 100 percent filters.
Your
new look
The final result from laser resurfacing may take several
months to fully appear. However, once the pinkness fades,
patients usually notice a significant improvement in the
quality of their skin and a fresher, smoother appearance.
It's
important to understand that your results will be long-lasting,
but not permanent. Remember, your new skin is not immune
to the effects of aging. In the months and years following
your laser treatment, your natural facial movements will
eventually cause any "expression" lines to recur.
As
with other methods of skin rejuvenation, laser treatments
can usually be repeated. However, by protecting yourself
from the sun and following a skin-care regimen recommended
by your plastic surgeon, you can help maintain your rejuvenated
look.
