Latissimus Flap
for Breast Mound Reconstruction

See Before & After Photos >>

latpatgallery.jpgWhen a flap is required for breast reconstruction, the latissimus flap is my usual second choice. (My preferred flap method for autologous tissue breast reconstruction is the TRAM flap.) The ultimate decision on which flap to use is made together with the patient, taking into consideration the various advantages and disadvantages of each option. As mentioned previously, flaps are most often required for breast reconstruction when radiation therapy has been used.

The latissimus flap takes the latissimus muscle from the back, along with a portion of skin and fatty tissue that overlies the muscle. The muscle is detached from its insertion along the back, but the blood vessels that supply the muscle are left intact. This flap of muscle, skin and fat is then tunneled under the skin to the anterior chest wall. It is then trimmed, sculpted, and sutured into place to form the breast mound.

There are certain pros & cons when considering the type of flap reconstruction to use. Certainly the interested reader will find a vast diversity of opinion and preference regarding favored types of breast reconstruction among reconstructive surgeons.

fleur.jpgOne of the major drawbacks of the latissimus flap reconstruction method is that (according to many sources in the plastic surgery literature) the flap does not provide enough volume for breast mound reconstruction by itself. In those circumstances, in order to achieve enough volume a breast implant may be necessary after the flap is in place. Because of this issue, I take a larger section of skin and fatty tissue along with the muscle during harvest in a fleur-de-lie pattern (as shown in image) which provides greater volume for the breast mound. This technique does leave a large T-shaped scar on the back, which is perhaps the biggest downfall of this reconstructive method.

One of the advantages of flap reconstruction is that the breast mound is typically reconstructed in a single stage. However, it is not uncommon at all to still require a small outpatient procedure several months after breast reconstruction to do any fine tuning on the breast mound, or to make any adjustments to the other breast (if the patient desires) to maximize symmetry. Examples of other breast surgery done at this setting include breast augmentation (enlargement), mastopexy (breast lift) or breast reduction.

Once the breast mound and any necessary symmetry procedures have been done, we are ready to go to the final stages of breast reconstruction: nipple/areolar reconstruction.

Latissimus Flaps:

TRAM Flaps:

What is the latissimus flap?

The latissimus is the large muscle on the upper back. This flap uses that muscle and a portion of the overlying skin and fatty tissue to recreate the breast mound.

What is the TRAM flap?

This flap takes one or both of the rectus abdominis muscles along with a large section of overlying skin and fatty tissue from the lower abdomen to recreate the breast mound.

Pros:

  • Very reliable blood supply, low risk of flap loss
  • Donor muscle loss very well tolerated
  • Surgical procedure time approx 2-3 hours

Pros:

  • Usually plenty of tissue available to reconstruct the breast mound
  • "Abdominoplasty"-like harvest of lower abdominal tissue can provide bonus benefit of the surgery

Cons:

  • Large T-shaped scar on the back
  • In some patients, there may be the need to augment breast size with implant

Cons:

  • Blood supply of flap not as reliable, has a much higher incidence of partial flap loss and "fat necrosis"
  • Harvest of the rectus abdominis muscle is not as universally well tolerated; this can weaken the abdominal wall with higher risk of postoperative back problems or abdominal hernia and pain
  • Surgical procedure time approx 4-6 hours
  • Longer post-operative hospitalization than latissimus reconstruction
