Some of the potential complications that may be discussed with you include reactions to anesthesia, blood accumulation that may need to be drained surgically and infection. Although rare, an infection that does not subside with appropriate treatment may require temporary removal of the implant. Changes in nipple or breast sensation may result from breast augmentation surgery, although they usually are temporary. When a breast implant is inserted, a scar capsule forms around it as part of the natural healing process. The capsule may sometimes tighten and compress the implant, causing the breast to feel firmer than normal.
Capsular contracture can occur to varying degrees.
If it is severe, it can cause discomfort or changes in the breast's appearance. In such cases, more surgery may be needed to modify or remove the scar tissue, or perhaps remove or replace the implant. Breast implants are not lifetime devices and cannot be expected to last forever. If a saline-filled implant breaks, its contents are harmlessly absorbed by the body within hours. A definite change in the size of the breast is clearly noticed.
