Options to correct deformity after breast explant? (Photo)

If it is determined that scar tissue is causing the deformity it can be released surgically.  At that point you may wish to also consider some fat grafting to improve overall shape.  I recommend meeting with a board certified plastic surgeon in your area for a consultation.

You would need to undergo a surgical procedure to release the scarring that is causing this fold and maybe use fat grafting to make up for any lost volume in the lower pole.  Massaging the breast in the meantime can help.
