Women who have breast implants may need revision surgery for various reasons, including: Implant leak or rupture: Breast implants are durable, but they are not designed to last forever. Rippling: With this complication, visible rippling of the breast implant can be seen on the surface of the skin. It is most common among thinner individuals. Capsular contracture: A scar tissue capsule naturally forms around the implant after it is surgically placed in the chest. Capsular contracture occurs when the capsule begins contracting around the implant, which can lead to breast distortion and pain. Bottoming out: When implants drop significantly on the chest, it makes the implants too low and the nipples too high in comparison. Revision surgery is performed to reposition and secure the implants in the proper position. Symmastia: With this complication, the pockets that contain the implants merge together across the center of the chest. Implant downsizing: Many women who have breast implants decide they want a smaller size. Change in type, shape, or position of implants: Women who are unhappy with the aesthetic results of primary breast implant surgery may opt for revision surgery to achieve their cosmetic goals.
