How it works
Everything begins with a consultation. Your doctors examine your chest and your back, assess how much skin and tissue can be used, review your treatment history (especially any radiation), and listen to what you hope for in shape and size. Together with your doctor, you decide whether to use the back flap on its own or to add an implant, and whether reconstruction happens during the same operation as the mastectomy or afterward.
The surgery is usually done under general anesthesia, which means you are fully asleep and feel nothing during the operation. How long it takes varies from case to case and depends on whether an implant is placed.
Your doctor makes an incision on your back and lifts a block of skin, fat, and latissimus dorsi muscle along with its feeding blood vessel. This tissue is passed through a tunnel under the skin at the armpit and rotated to the front of the chest — the blood vessel stays connected so the tissue keeps its supply and stays alive. There, your doctor shapes it into a breast that balances with the other side.
If more volume is needed, your doctors can place an implant behind the flap. The incisions on your back and chest are closed, and small drains are usually placed to let fluid escape in the first few days. Rebuilding the nipple and areola, if you want it, is usually done as a separate step once the tissue has settled.
