Your implants are tough and meant to last all sorts of stress over time. That being said, our own bodies give out with time as does every living and and just about everything else in life (e.g. cars, microwave ovens) and so is the case for implants. For silicone implants prior to 2006, ruptures occur at rates of approximately 1-2% per year for the first ten years then markedly increases after that time period. A rupture or deflation of the implant may be experienced at any point after the initial augmentation; this complication may be increased by an under-filling or overfilling of saline solution into the implant, excessive compression, trauma, and other causes. (If the implant shell if not filled with the correct amount of saline, there may be a crease or fold in the shell which often leads to a rupture). You will be able to self-diagnose the need for an implant exchange (if using a saline implant) because if the current implant ruptures, the breast will shrink to approximately its preoperative size. A silicone implant that has a rupture is usually noted on a routine mammogram or MRI scan. In either case although the situation needs to be corrected on a timely basis, it is not dangerous to your health from our current knowledge base. Silicone implants after 2006 are more cohesive and less likely to leak or have silicone migration.
