Burn injuries account for over 100,000 hospital admissions per year.
With the opening of many specialized burn centers for acute burn injuries,
death rates from severe burns have dropped significantly. Survivors,
however, are often left, with functional impairment and grotesque distortion
of appearance. Particularly is located in the head and neck regions.
Functional impairment in the head and neck region results in drooling,
neck contracture, corneal exposure, nasal airway blockage, lip incompetence,
inability to make facial expressions, etc. As a specialist in reconstruction
and burn rehabilitation, the plastic surgeon is an integral part of the burn
team. Scarring, whether it's normal or hypertrophic, contractures, loss of
functional body parts, and change in the color and texture of burned skin
are processes common to all burned patients that have the potential to be
reconstructed.
A realistic approach, however, is necessary to harmonize patients'
expectations (which are often very high) with the likely outcomes of
reconstructive surgery. Burn reconstruction starts when a patient is
admitted with acute burns and lasts until the patient's expectations
have been reached or there is nothing else to offer. However, even when
this time has come, the patient-surgeon relationship may still continue
and can last a lifetime.

What are the reconstructive options?
As with the initial treatment of severe burns, reconstructive burn
procedures often require skin grafting or flap reconstruction. Skin grafts
involve taking skin from unburned sites on the body (known as donor sites).
This skin is then placed (grafted) onto the burn wound. The grafted skin
attaches to the underlying wound and effectively closes it.
Skin grafts are often used in the revision of scar contracture, which
is another unfortunate consequence of burns. A contracture is a permanent
shortening of the muscle, tendon or scar tissue producing deformity or
distortion. Contractures often restrict normal body movement. In these
reconstruction procedures, a surgeon excises (removes) an existing scar
and applies a graft to the site of the removed scar. Skin grafting for
burn reconstruction is a surgical procedure and is usually performed in
the hospital on an inpatient basis under general anesthesia. As with
grafts used for initial treatment, recovery may take several weeks.
A graft "takes" or is successful when new blood vessels and tissue form
in the injured area. Sometimes, skin grafts do not take because of early
complications such as infection (the most common cause of graft failure),
shearing (mechanical forces that cause a graft to detach from the skin),
or fluid collections underneath the graft. While grafting is a proven and
effective treatment, it is important to understand that all grafts leave
some scarring at both the donor and recipient sites. More Burn Surgery Facts...
Split-Thickness Grafts
Split-thickness skin grafts (STSGs) are grafts that include the
thin top layer of the skin (epidermal layer) and part of the underlying
thicker component of skin (dermal layer). Split thickness skin grafts
are often removed from flat body surfaces such as the abdomen, thigh
or back. These grafts are sewn or stapled into place on the wound/burn
and covered with compression dressings (tightly wrapped elastic bandages)
to provide firm contact. Occasionally, graft sites are left open to air.
Split-thickness skin grafts are generally not used for weight-bearing
parts of the body or for areas subject to friction such as hands or
feet. The advantages of STSGs include less tissue use, an improved
chance of graft survival and minimized donor site damage. However,
one disadvantage is that these grafts tend to contract more than
full-thickness skin grafts. More Burn Surgery Facts...
Full-Thickness Grafts
Full-thickness skin grafts (FTSGs) consist of both the epidermal
and complete dermal skin layers. This type of graft is used instead
of a split-thickness skin graft when cosmetic outcome is essential
and contracture is not tolerable for function. The thicker the graft,
the less the potential there is for contracture. Other advantages
include increased resistance to trauma over thin grafts and less
distortion functionally and cosmetically. More Burn Surgery Facts...
Skin Flaps
Sometimes, the area requiring reconstruction lacks the blood
supply needed to support a skin graft. Skin flaps, an advanced form
of skin grafting, is a complex procedure in which skin, along with
underlying fat, blood vessels and sometimes muscle, is moved from a
healthy part of the body to the injured site. In skin flaps located
adjacent to the wound site, blood supply may remain attached at the
donor site. In instances where the skin flap needs to be attached to
a wound elsewhere on the body, surgeons will reattach blood vessels
in the flap at the new site through microvascular surgery. More Burn Surgery Facts...
Tissue Expansion
Tissue expansion is an important and valuable addition to the
reconstructive armamentarium of plastic and reconstructive surgeons. It
is a safe technique and can be used successfully for the rehabilitation
of selected burn victims. It allows the creation of skin that maintains
all the skin characteristics in the area (sensation, texture, color,
and hair follicles) with minimal or no donor site complications.
At the time of tissue expander placement, a moderate volume
of saline is placed, but only enough to fill the space without too much
tension on the suture line. Inflation schedules must be individualized
according to the nature and location of the deformity. Filling is
generally performed at weekly intervals, and each inflation proceeds
to a point of slight discomfort or blanching of the skin overlying
the implant.
After making the decision to use tissue expansion, the
surgeon must choose the type of flap to be used. When the desired
expansion has been achieved, the expander is removed and the flap is
moved to the recipient site.
Patient selection is very important, since this process
implies a temporary but significant cosmetic deformity and may interfere
with social life and other activities. Only well-motivated persons
should be considered as candidates for the procedure, following
extensive pre-surgery discussion. More Burn Surgery Facts...
Donor Sites
When performing a skin graft, the surgical team must pay attention
to the donor site as well since that can also result in poorly healed
tissue. Thick split-thickness and full-thickness skin grafts result in
deeper donor site wounds that require longer healing time and may
result in contraction and hypertrophic scarring.
With thicker split-thickness and full-thickness skin
grafts, dermal tissue may be permanently lost at the donor site. The
dermal layer cannot grow back by itself and most often results in scar
formation. Healing time for most split-thickness skin grafts is
approximately 10 to 20 days. Most full-thickness skin grafts require
a longer 21 to 90 day period. As a result, medium-thickness split
grafts are frequently used as a compromise to provide improved graft
survival and durability with minimized donor site complications. More Burn Surgery Facts...
How do surgeons decide what to use?
In evaluating your condition, a plastic surgeon will be guided by a set
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 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, and 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.
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. More Burn Surgery Facts...
What are the risks and concerns about Burn reconstruction?
As with any surgery, complications can occur. Individuals vary greatly
in their anatomy and healing ability and the outcome is never completely
predictable. Complications include infection; excessive bleeding, such as
hematomas (pooling of blood beneath the skin); significant bruising and
wound-healing difficulties (hypertrophic scarring and keloid formation);
and problems related to anesthesia and surgery. Once again, it is always
important to be realistic in your expectations and to have good
communication with your plastic surgeon regarding the possible outcome.
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. More Burn Surgery Facts...
