Have you ever performed a re-do of a breast reduction?

A second breast reduction, or "re-reduction," can be an option, but it comes with some specific risks. One of the primary concerns is preserving the blood supply to the nipple and areola. If the blood supply is compromised, it could lead to nipple necrosis, though this is rare with careful planning. Altered nipple sensation or loss of sensation is also a potential risk. An experienced surgeon will understand the implications of your previous surgeries and have experience with revision procedures.
To minimize risks, it's essential to consult with an experienced plastic surgeon who specializes in breast revision procedures. They can assess your previous surgery and create a tailored plan to ensure the best outcome while addressing the unique challenges of a second breast reduction.

Thank you for the good question.  It is generally safe to undergo additional reduction surgery but care must be taken to avoid complications.
One of the concerns when repeating breast reduction surgery is related to blood flow to the remaining breast tissue; is important to perform the operation in such a fashion that the blood flow to the nipple/areola/breast tissue is not compromised. The part of the tissue that is left in place after breast reduction surgery is called the “pedicle"; this segment of tissue is responsible for delivering the blood supply to the nipple/areola/ breast tissue. If the pedicle (that was used during the previous breast reduction procedure) is cut then the blood flow to tissues may be compromised leading to serious complications such as tissue necrosis etc.
It will be helpful for you to find the previous surgeon's operative report prior to the redo surgery, if you are working with a different surgeon. Sometimes, previous operative reports are not available;  careful planning of the repeat breast reduction procedure can nevertheless help prevent complications.
 If your initial operation was done several years ago, it is likely that a significant amount of blood supply has been established.   Best wishes.

Thank you for your question. The need to repeat a breast reduction is a fairly common occurrence. It is safe to perform, ideally if the technique used the first time is available it makes the procedure easier, but it is safe and commonly done. I would recommend you see a board certified plastic surgeon in your area for a consultation.
