Chances are your new breasts won't look exactly like your natural ones did. However, the contour of your new breasts can usually be restored so that your silhouette looks similar to your silhouette before surgery.
Breast reconstruction with flap surgery is the most complex breast reconstructive option. Your surgeon transfers a section of skin, muscle, fat and blood vessels from one part of your body to your chest to create a new breast mound. In some cases, the skin and tissue need to be augmented with a breast implant to achieve the desired breast size.
Autologous tissue breast reconstruction uses one of two surgical methods:
- Pedicle flap surgery. The surgeon cuts some of the blood vessels to the tissue to be transferred but keeps other blood vessels intact. Tunneling the tissue beneath your skin to your chest area, the surgeon then creates the new breast mound or pocket for the implant.
- Free flap surgery. The surgeon disconnects the tissue completely from its blood supply and reattaches the tissue to new blood vessels near your chest. Because of reattaching blood vessels, free flap surgery typically takes longer than does pedicle flap surgery. The recovery period for this type of surgery is longer, too.
Types of flap surgery
The tissue for reconstructing your breast may come from your abdomen, back or — less commonly — your buttocks. Your surgeon determines which method is best for you based on your body type and your medical and surgical history.
Abdomen (TRAM flap). Your surgeon removes tissue — including muscle — from your abdomen in a procedure known as a transverse rectus abdominal muscle (TRAM) flap. The TRAM flap can be transferred as a free flap or a pedicle flap.
A pedicle TRAM flap uses your whole rectus muscle — one of the four major muscles in your abdomen. For a muscle-sparing free TRAM flap, your surgeon takes only a portion of your rectus abdominal muscle, which may help you retain abdominal strength after surgery.
Abdomen (DIEP flap). A newer procedure, deep inferior epigastric perforator (DIEP) flap, is similar to muscle-sparing free TRAM flap, but only skin and fat are removed. Minimal abdominal muscle tissue is taken to form the new breast mound. Reattaching blood vessels requires expertise in surgery through a microscope (microsurgery).
An advantage to this type of breast reconstruction is that you'll retain more strength in your abdomen. If your surgeon can't perform a DIEP flap procedure for anatomical reasons, he or she might opt for the muscle-sparing free TRAM flap instead.
A variation of the DIEP flap, the superficial inferior epigastric artery (SIEA) flap, uses the same abdominal tissue but relies on blood vessels that aren't as deep within the abdomen. This provides a less invasive option, but not all women's SIEA blood vessels are adequate for this type of flap surgery.
- Back (latissimus dorsi flap). This surgical technique takes skin, fat and muscle from your upper back, tunneling it under your skin to your chest. Because the amount of skin and other tissue is generally less than in a TRAM flap surgery, this approach may be used for small and medium-sized breasts or for creating a pocket for a breast implant. Although uncommon, some women experience muscle weakness in the back, shoulder or arm after this surgery.
- Buttocks (gluteal flap). A gluteal flap is a free flap procedure that takes tissue from your buttocks and transplants it to your chest area. A gluteal flap may be an option for women who prefer tissue reconstruction but who don't have enough extra tissue in their backs or abdomens.
- Inner thigh (TUG). Another newer option, the transverse upper gracilis (TUG) flap, uses muscle and fatty tissue from the bottom of the buttocks to the inner thigh. TUG flap surgery, which isn't available everywhere, may be an option for women whose thighs touch and who have small to medium-sized breasts.
Because adequate blood supply is critical to the survival of transplanted tissue in flap surgery, your surgeon may prefer not to perform a pedicle flap procedure if you're a smoker or if you have diabetes, vascular disease or a connective tissue disorder. Also, obesity may preclude you from having a pedicle TRAM flap.
In general, flap breast reconstruction surgery is more extensive than is mastectomy or implant reconstruction. Flap procedures result in larger incisions that take longer to heal, so they require a longer recovery period and may require a longer hospital stay.
Breast reconstruction may also entail reconstruction of your nipple, if you choose, including tattooing to define the dark area of skin surrounding your nipple (areola).
You may be tired and sore for a few weeks after your surgery. Your doctor can prescribe medication to control your pain. You may have drainage tubes in place for a short time after your surgery to remove excess fluids that collect in the surgical site.
Wearing an elastic bandage or support bra can help keep swelling down and support your breast while it heals.
You'll also have stitches (sutures) after your surgery. They'll probably be absorbable sutures, though, so you won't need to have them removed. Scarring is permanent, but the scars generally fade over time.
Getting back to normal activities may take up to six weeks or more. Your doctor will let you know of any restrictions to your activities, such as avoiding overhead lifting or strenuous physical activities. Don't be surprised if it seems to take a long time to bounce back from surgery — some women report that it takes as long as a year or two before feeling completely healed and back to normal.
Generally, you'll follow up with your plastic surgeon on a yearly basis to monitor your reconstructed breast. Make an appointment sooner than that, however, if you have concerns.
Future breast cancer screening
If you've only had one breast reconstructed, you'll need regular screening mammography on your other breast. Mammography isn't necessary on breasts that have been reconstructed, as the mastectomy removes most of your breast.
You may also choose to perform breast self-exams on your natural breast and the skin and surrounding area of your reconstructed breast. This may help you become familiar with your breast after surgery, so that you can be alert to any new changes.
