In those tragic cases where a full mastectomy is required to treat breast
cancer, reconstruction is a welcome option. With modern techniques and materials
it is possible to restore appearance to a near invisible state. Carried out
by specialized plastic surgeons, restoration is now commonplace.
There are a variety of approaches and each case is unique. Consultation with
a physician is required in order to select the one that is right for you.
Breast implants are one commonly chosen option. Today, these are usually saline
filled bags with a silicon outer shell. They are placed in front of the chest
wall muscles under the skin covering the breast area.
In years past, silicon filled implants were more typical. There was a concern
for the possibility of silicon leaking into the body and causing immune system
problems. But the FDA recently announced, after years of careful study, that
there was little basis for worry and silicon breast implants are now legal
again. Some prefer them for their different behavior.
In some cases, reconstruction is done during the mastectomy. In others, physicians
recommend a waiting period to allow the body to heal before any further surgery.
Each case is individual and can only be decided on its own merits.
Typically, though, two-stage delayed reconstruction is performed if the skin
and chest wall tissues are flat. An implant, called a tissue expander that
functions like a balloon under the tissue, is placed beneath the muscle. The
surgeon then injects saline in stages over a period of time to gradually fill
the sac. In some instances, the expander itself becomes the implant. In other
cases, in a later procedure, the expander is removed and replaced with a permanent
implant.
Tissue flap procedures are another category of breast surgery. These use skin
from the stomach, the thighs or other area as part of the total process.
TRAM (transverse rectus abdominis muscle flap) is one of the most common types,
which uses tissue from the lower abdominal wall. A pedicle flap leaves the
tissue attached to the original blood supply and stretches the tissue up the
breast area. A free flap procedure removes the tissue entirely, along with
muscles, fat, and blood vessels and reattaches them to blood vessels under
the chest.
Another, about equally common, uses tissue from the upper back. A flap is
moved in front of the chest wall to create a pocket. A breast implant is then
inserted into the pocket. There are other procedures as well, such as one that
uses gluteal muscle tissue.
In each case, nipple and/or areola reconstruction may or may not be part of
the total surgery. It may be done later or not at all. Rarely is the nipple
from the original breast used as a replacement out of concern that it may regenerate
the cancer.
Reconstructive surgery is not entirely without risks, of course.
There can be the usual surgical complications, such as infection or scarring,
such as capsular contracture in which scar tissue forms around the implant.
Breast implants may not last a lifetime, depending on individual circumstances,
such as age. Replacing them may require an additional surgery later in life.
The final result may or may not be what the patient was expecting. Only a full
consultation with a physician can provide a realistic assessment of likely
outcomes.
