Breast implants are prostheses consisting of a gel-like or fluid material in a flexible sac. They may be placed either under or over the chest muscles. Implants are available filled with saline or silicone gel (this includes both traditional and ‘gummy bear’ implants). Besides placement location and type of fill, doctors and their patients will decide whether to perform immediate or delayed reconstruction. Some good information regarding implants can be found here.
