When a tear or a hole appears in the silicone shell surrounding a breast implant, then this is known as an implant rupture. Rupturing can apply to both saline and silicone breast implants as saline implants also have a silicone shell. Polyurethane implants are also not immune from rupture as these too also have an outer shell, similar to silicone implants. However, modern silicone elastomer shells are much tougher than those of earlier implants. Consequently, the risk of a rupture occuring in modern implants is far less likely, particularly with the higher risk saline implants.
Damage to the body does not necessarily result from an implant rupture. Since saline implants contain sterile saline (salt water) solution, this can quite easily be absorbed and disposed of by the body through natural processes. However, if this does occur, then the unfortunate individual is left with s deflated implant which will be most noticable in appearance. The deflated, ruptured implant will need to be surgically replaced.
Depending on the type of filler used in silicone implants, then rupture of the outer shell may or may not result in leakage of the interior silicone. With cohesive gel filled implants, the silicone should remain intact and you are unlikely to even know that an implant has ruptured. Occasionally, small lumps of silicone called siliconomas may appear in the breast area when an implant ruptures. Polyurethane implants have similar outlook but these more modern implants are filled with the low risk cohesive gel.
