We've just finished looking at our data in the first five years since I started using these devices in 2001. Of course, I would like and hope to have longer data as the years go by.
At the present time, my re-operation rate for any indication—which would be for any patient, whether for reconstruction because a patient had changes to the breast because of breast feeding or for replacement on an implant—is 5.7% over the period of the study, and that could be for a variety of reasons. It could be for mal-positioning, such as turning or changing in the position of the implant. It could be for asymmetry, which is a common potential problem, especially when you're reconstructing a single breast and trying to match it to a natural breast on the opposite side. It could be for issues related to scar tissue or contracture around the implant.
I have not identified a ruptured gel implant that I've used in my practice. There may be some I have not identified, which would only be identified through longer follow-up or MRIs of every single patient, but I have not seen a ruptured device yet.
