These two options are quite different. Fat grafting is a method of transferring small amount of fat into a breast, layer by layer. The fat cells survive by vascular ingrowth from the wound bed. This is a very useful technique to improve contour of the reconstructed breast and thickness of the mastectomy skin flap. It also provides a small improvement in the volume of the reconstructed breast.
However, the recipient bed must be a healthy and well vascularized field for the fat graft to take. In a radiated breast, the skin is fibrotic — often hard — and the vascular blood supply is compromised. If the fat cells do not get new vascular ingrowth from the wound bed, the body will clear these fat cells in a process call resorption.
The rates of resorption in fat transfer are from 50 to 70%.
For example, a transfer fat volume of 200 cc, only 100cc (50%) of the transferred fat cell will survive in the procedure. Therefore, fat grafting technique is mainly used to improve contour of a reconstructed breasts with a minor improvement of volume. It is not meant as a technique to rebuild an entire breast.
There are complications from fat grafting, such as painful fat necrosis, fat cyst oil, uneven contour, and infection from fat necrosis.
Fascial cutaneous flap is a technique of transporting a large amount of tissue composing of skin and subcutaneous fat with its own nourishing blood vessels to reconstruct a breast. The flap blood supply is hooked up to the recipient chest blood vessels and thus become a living tissue immediately at the time of surgery. It does not depend on the slow vascular ingrowth from the wound bed. The source of the tissue flap can be catered according to the woman’s body habitus. Depend on the location a woman stores her excess skin and fat, the sites become the most suitable donor site for a flap in breast reconstruction. A plastic surgeon also takes into consideration the resultant scar to see whether it will the best donor site for a flap. This is also known as tailored autologous tissue (flap) reconstruction. The most common donor sites for flaps in breast reconstruction are lower abdomen, lower back, the flanks, upper buttocks, and
