Context: Breast Reconstruction After Mastectomy

What is flat closure?

A flat closure (also called aesthetic flat closure) is surgery done to rebuild the shape of the chest wall after the removal of one or both breasts. It is also a surgical option for people who have had their breast implants removed.

Source links and citations

During an aesthetic flat closure, a surgeon removes extra skin, fat, and other tissue in the breast area. The remaining tissue is then tightened and smoothed out so that the chest wall appears flat and contoured. Simply forgoing additional procedures to reconstruct the breast(s) after a mastectomy will not achieve a flat closure (11).
