Complications can occur with breast implants that may require removal of the implant. Examples of complications include infection, extrusion (implant exposure at the surface of the skin), rupture, and contracture. Research evidence reveals that the incidence of microbial contamination of the luminal saline of the implant is unlikely. Normal saline is a physiologic solution consistent with an organism's normal functioning.
A contracture occurs when the capsule surrounding a breast implant tightens. Extreme cases can cause the breast to feel hard and painful. Disfigurement may also result if the capsule surrounding one implant contracts and the other does not, or if the capsule contracts unevenly. Contractures have been graded according to the Baker Classification as follows:
