Shaping of the breast is done before and after the microsurgery is performed. There are many issues that contribute to the ultimate contour, and they include:
The shape and possible need for further surgery on the other breast
Skin sparing incisions
Immediate reconstruction
Delayed reconstruction
Old scars
Radiation
The most significant factor is the technical skill and artistic sense of the surgeon. Without excellent technical skill and an artists eye, results can range from failure to an aesthetically displeasing outcome.


Above, a result with a skin sparing mastectomy (left) and a delayed reconstruction (right). The abdominal skin island present on the breast is smaller for the immediate than the delayed reconstruction. The nipple areola reconstruction is usually scheduled for a later date, when all tissue has healed. Secondary revision surgery may be required on the breast to approve appearance or symmetry and depends on patient body type and desires. Later revisions are sometimes done in conjunction with abdominal scar revision.
