Unless there is a good reason to replace them, absolutely not. Like everything else in the world, however, breast implants are not designed to, and will not, last forever. Occasionally, they need to be replaced. Most of the time, patients who undergo implant revision simply want bigger or smaller implants. Sometimes, capsular contracture of the implant requires surgical intervention. Malposition of the implants and deflation of saline implants may necessitate a secondary revision surgery to exchange for new implants. In any revision surgery, the goal is to restore beauty and shape to the breasts.
Any one of a number of things can induce a breast implant revision. Many of our breast implant patients, after years, sometimes decades with their implants simply want to change the size of their implants. As we age our bodies change.
