There are many reasons why a woman may choose to have their breast augmentation �revised.� Essentially, there is something about the initial outcome that they are no longer happy with. Sometimes, they may be displeased with the implant placement or the size. For others, pregnancy or weight loss has changed their satisfaction with the initial implant. And, other times, the implants need to be replaced because of deflation or a revision needs to be done due to capsular contracture.
