What is reconstructive surgery?
It's
estimated that more that one million reconstructive
procedures are performed by plastic surgeons every
year. Reconstructive surgery helps patients of
all ages and types - whether it's a child with
a birth defect, a young adult injured in an accident,
or an older adult with a problem caused by aging.
The goals of reconstructive
surgery differ from those of cosmetic surgery.
Reconstructive surgery is performed on abnormal
structures of the body, caused by birth defects,
developmental abnormalities, trauma or injury,
infection, tumors, or disease. It is generally
performed to improve function, but may also be
done to approximate a normal appearance.
Cosmetic surgery is performed
to reshape normal structures of the body to improve
the patient's appearance and self-esteem.
Although no amount of surgery
can achieve "perfection," modern treatment
options allow plastic surgeons to achieve improvements
in form and function thought to be impossible
10 years ago.
This will give you a basic understanding
of some commonly-used techniques in reconstructive
surgery. It won't answer all of your questions,
since each problem is unique and a great deal
depends on your individual circumstances. Please
be sure to ask your doctor to explain anything
you don't understand. Also, ask for information
that specifically details the procedure you are
considering for yourself or your child.

All surgery
carries some uncertainty and risk
When reconstructive surgery is performed by a
qualified plastic surgeon, complications are infrequent
and usually minor. However, individuals vary greatly
in their anatomy and healing ability and the outcome
is never completely predictable.
As with any surgery, complications
can occur. These may include infection; excessive
bleeding, such as hematomas (pooling of blood
beneath the skin); significant bruising and wound-healing
difficulties; and problems related to anesthesia
and surgery.
There are a number of factors
that may increase the risk of complications in
healing. In general, a patient is considered to
be a higher risk if he or she is a smoker; has
a connective-tissue disease; has areas of damaged
skin from radiation therapy; has decreased circulation
to the surgical area; has HIV or an impaired immune
system; or has poor nutrition. If you regularly
take aspirin or some other medication that affects
blood clotting, it's likely that you'll be asked
to stop a week or two before surgery.

Options
in wound treatment
In deciding how to treat a wound, a plastic surgeon
must carefully assess its size, severity, and
features: Is skin missing? Have nerves or muscles
been damaged? Has skeletal support been affected?
As you and your plastic surgeon
form your surgical plan, it's important to have
a clear understanding of what will happen during
the procedure. Asking questions is key to making
an informed decision.
Direct closure is usually performed
on skin-surface wounds that have straight edges,
such as a simple cut. Maximum attention is given
to the aesthetic result, taking extra care to
minimize noticeable stitch marks.

Advanced
wound care: flap surgery/microsurgery
Though success will largely depend on the extent
of a patient's injury, flap surgery and microsurgery
have vastly improved a plastic surgeon's ability
to help a severely injured or disfigured patient.
Using advanced techniques that often take many hours
and may require the use of an operating microscope,
plastic surgeons can now replant amputated fingers
or transplant large sections of tissue, muscle or
bone from one area of the body to another with the
original blood supply in tact.
A flap is a section of living
tissue that carries its own blood supply and is
moved from one area of the body to another. Flap
surgery can restore form and function to areas
of the body that have lost skin, fat, muscle movement,
and/or skeletal support.
A local flap uses a piece of
skin and underlying tissue that lie adjacent to
the wound. The flap remains attached at one end
so that it continues to be nourished by its original
blood supply, and is repositioned over the wounded
area.
A regional flap uses a section
of tissue that is attached by a specific blood
vessel. When the flap is lifted, it needs only
a very narrow attachment to the original site
to receive its nourishing blood
supply from the tethered artery and vein.
 |
| With
flap surgery, tissue, sometimes including
underlying fat and muscle, is taken from the
back and tunneled to the front of the chest
wall to support the reconstructed breast. |
 |
| The
transported tissue forms a flap to cover a
breast implant, or it may provide enough bulk
to form the breast mound without an implant. |
A musculocutaneous flap,
also called a muscle and skin flap, is used when
the area to be covered needs more bulk and a more
robust blood supply. Musculocutaneous flaps are
often used in breast reconstruction to rebuild a
breast after mastectomy. This type of flap remains
"tethered" to its original blood supply.
In a bone/soft tissue flap,
bone, along with the overlying skin, is transferred
to the wounded area, carrying its own blood supply
 |
| A
bone/soft tissue flap is used to reconstruct
the nose following skin cancer excision. |
 |
| The
incision lines of the flap are hidden within
the natural creases of the nose and face. |
A microvascular
free flap is a section of tissue and skin that
is completely detached from its original site
and reattached to its new site by hooking up all
the tiny blood vessels.
Other reconstructive procedures
In addition to correcting cuts and other surface
wounds, plastic surgeons also regularly treat
both cancerous and non-cancerous growths and problems
with the supporting structures beneath the skin.
Tumors, both cancerous and benign,
vary widely in type, severity and recurrence.
The removal method chosen will depend largely
on the type of growth, what stage it's in, and
its location on the body.
Skin cancers and growths are
usually removed by excision and closure, in which
the growth is simply removed completely with a
scalpel, leaving a small thin scar. If the cancer
is large or spreading, major surgery may be necessary,
using flaps to reconstruct the affected area.

Who has
reconstructive surgery?
There are two basic categories of patients: those
who have congenital deformities, otherwise known
as birth defects, and those with developmental
deformities, acquired as a result of accident,
infection, disease, or in some cases, aging.
Some common examples of congenital
abnormalities are birthmarks; cleft-lip and palate
deformities; hand deformities such as syndactyly
(webbed fingers), or extra or absent fingers;
and abnormal breast development.
Burn wounds, lacerations, growths,
and aging problems are considered acquired deformities.
In some cases, patients may find that a procedure
commonly thought to be aesthetic in nature may
be performed to achieve a reconstructive goal.
For example, some older adults with redundant
or drooping eyelid skin blocking their field of
vision might have eyelid surgery. Or an adult
whose face has an asymmetrical look because of
paralysis might have a balancing facelift. Although
appearance is enhanced, the main goal of the surgery
is to restore function.
Large, sagging breasts are one
example of a deformity that develops as a result
of genetics, hormonal changes, or disease. Breast
reduction, or reduction mammaplasty, is the reconstructive
procedure designed to give a woman smaller, more
comfortable breasts in proportion with the rest
of her body.
In another case, a young child
might have reconstructive otoplasty (outer-ear
surgery) to correct overly-large or deformed ears.
Usually, health insurance policies will consider
the cost of reconstructive surgery a covered expense.
Check with your carrier to make sure you're covered
and to see if there are any limitations on the
type of surgery you're planning. Work with your
doctor to get pre-authorization from the insurer
for the procedure

Planning
your surgery
In evaluating your condition, a plastic surgeon
will be guided by a se t of rules known as the reconstructive
ladder. The least-complex types of treatments-such
as simple wound closure-are at the lower part of
the ladder. Any highly complex procedure-like micro-surgery
to reattach severed limbs-would occupy one of the
ladder's highest rungs. A plastic surgeon will almost
always begin at the bottom of the reconstructive
ladder in deciding how to approach a patient's treatment,
favoring the most direct, least-complex way of achieving
the desired result.
The size, nature and extent
of the injury or deformity will determine what
treatment option is chosen and how quickly the
surgery will be performed. Reconstructive surgery
frequently demands complex planning and may require
a number of procedures done in stages.
Because it's not always possible
to predict how growth will affect outcome, a growing
child may have to plan for regular follow-up visits
on a long-term basis to allow additional surgery
as the child matures.
Everyone heals at a different
rate-and plastic surgeons cannot pinpoint an exact
"back-to-normal" date following surgery.
They can, however, give you a general idea of
when you can expect to notice improvement.

Skin
grafts
A wound that is wide and difficult or impossible
to close directly may be treated with a skin graft.
A skin graft is basically a patch of healthy skin
that is taken from one area of the body, called
the "donor site," and used to cover another
area where skin is missing or damaged. There are
three basic types of skin grafts.
A split-thickness skin graft,
commonly used to treat burn wounds, uses only
the layers of skin closest to the surface. When
possible, your plastic surgeon will choose a less
conspicuous donor site. Location will be determined
in part by the size and color of the skin patch
needed. The skin will grow back at the donor site,
however, it may be a bit lighter in color.
A full-thickness skin graft
might be used to treat a burn wound that is deep
and large, or to cover jointed areas where maximum
skin elasticity and movement are needed. As its
name implies, the surgeon lifts a full-thickness
(all layers) section of skin from the donor site.
A thin line scar usually results from a direct
wound closure at the donor site.
A composite graft is used when
the wound to be covered needs more underlying
support, as with skin cancer on the nose. A composite
graft requires lifting all the layers of skin,
fat, and sometimes the underlying cartilage from
the donor site. A straight-line scar will remain
at the site where the graft was taken. It will
fade with time.

Tissue
expansion
Tissue expansion is a procedure that enables the
body to "grow" extra skin by stretching
adjacent tissue. A balloon-like device called an
expander is inserted under the skin near the area
to be repaired and then gradually filled with salt
water over time, causing the skin to stretch and
grow. The time involved in tissue expansion depends
on the individual case and the size of the area
to be repaired.
The advantages of tissue expansion
are many-it offers a near-perfect match of skin
color, sensation, and texture; the risk of tissue
loss is decreased because the skin remains connected
to its original blood and nerve supply; and scars
are less apparent than those in flaps or grafts.
The expander temporarily creates what can be an
unsightly bulge, making this option undesirable
for some patients.
 |
| Tissue
expansion is ideal for scalp repair because
the stretched skin on the scalp retains normal
hair growth. Most other body tissue does not
grow hair to the same degree. |
 |
| Following
tissue expansion, the repaired scalp restores
a more natural appearance. |
|

Hand
surgery
Whether the defect is congenital or acquired, plastic
surgeons can usually restore comfort, mobility,
and normal appearance to patients with hand problems.
Acquired defects include carpal tunnel and other
painful conditions caused by pressure on the nerves
(usually at the wrist or elbow); trigger fingers,
a condition caused by swelling of a flexor tendon
in the hand; ganglion cysts, a benign cystic growth
and scar contracture which occurs when a wound or
burn on the hand heals poorly and forms scar tissue
that curls the fingers or restricts mobility. Dupuytren's
disease causes a similar problem of hand contracture.
Children born with syndactyly
(webbed fingers) can benefit from finger separation,
where a zig-zag-type incision separates the fingers
and rearranges the tissue between them, preventing
growth deformities. If a child had polydactyly
(extra fingers), correction is often more than
simply removing the extra digits. The surgeon
may also need to balance the tendons of the hand
and stabilize the remaining finger joints so that
the hand functions as normally as possible. Plastic
surgeons also reconstruct missing digits, including
the thumb, which supplies half of the hand's function.
 |
| In
a typical syndactyly, two fingers are fused
together. The surgeon often uses zig-zag incisions
to separate the fingers, creating triangular
skin flaps. |
 |
| Skin
flaps cover most of the exposed areas between
the fingers. Skin grafts are used to fill
the shaded areas at the base of the fingers. |

If
you're considering laser surgery...
In the past decade, laser technology has revolutionized
many areas of plastic surgery. The laser's allure
comes from its ability to "blast" away
or diminish imperfections or growths with a minimum
of bleeding, bruising, and scarring.
Currently, there are many types
of lasers available, with many more under development.
Therefore, it's important to understand that not
all lasers are alike.
If you're planning to have laser
surgery, it's best to find a doctor who is well
experienced with, and has access to, a variety
of lasers.
The yellow pulsed-dye laser
uses a type of dye as its active medium. It has
a pulsing beam that is heavily absorbed by hemoglobin,
which gives blood its red color. This laser is
often used for performing surgery on children
who have pinkish birthmarks called port-wine stains.
The laser destroys the abnormal blood vessels,
lightening the birthmark to the point of being
barely noticeable. Scarring, which was a problem
with earlier laser models, is minimal with the
yellow pulsed-dye laser.
The "pigment-blasting"
laser family-the Q-switch ruby, the Q-switch YAG,
and the alexandrite is a new group of lasers effective
in eliminating the black and blue pigments of
tattoos, pigmented lesions and the brown patches
and spots that often occur with aging. Though
the removal of decorative tattoos is considered
a cosmetic procedure, the removal of "traumatic
tattoos" is a reconstructive process. Traumatic
tattoos occur when material particles are forced
under the skin through an accident-as in an explosion
or a collision.
The carbon dioxide laser, sometimes
called the "workhorse" of lasers, is
an invisible light absorbed by water, the primary
component of human skin. When the beam is focused,
it can cut tissue and seal blood vessels simultaneously.
When defocused, it vaporizes. These characteristics
make it the treatment of choice for removing warts
and many types of skin growths.
The YAG laser has been shown
to be effective in the surgery of various types
of hemangiomas, which are skin growths with heavy
concentrations of blood vessels. It delivers highly-focused
energy and-unlike other lasers-its tip can be
placed directly on the skin, mimicking a scalpel.
The argon laser is similar to
the yellow pulsed-dye laser. The argon laser emits
a blue-green light that is absorbed heavily by
the color red. It is particularly effective in
treating abnormalities that have a proliferation
of blood vessels, such as blood blisters, "spider"
blood vessels on the face, "strawberry"
birthmarks, hemangiomas, and bulky vascular tumors.
The copper vapor laser is a
newer type of laser that emits a yellowish light.
Its uses include treating brown or red pigmented
areas.
The number of laser treatments
you'll need depends largely upon the size and
severity of the defect. A child with a large birthmark
may need six to ten laser treatments to achieve
satisfactory results. Only one treatment may be
needed to remove some small spider veins on the
face.
Lasers have a number of valuable
uses, but a laser should not be viewed as a "magic
wand" that improves the results of any type
of surgery. For traditional kinds of surgery and
most plastic surgery, the scalpel is still the
proven instrument of choice.
