Hello,
I am sorry you have had such a difficult and unpleasant experience with breast augmentation. In reality, both Drs Pozner and Rand are correct. Dr Rand has made the assumption that all avenues have been thoroughly taken to prevent recurrance. Dr Pozner is delineating how aggressive a surgeon has to be to try to erradicate recurrance. In as few words as possible, capsular contracture is almost always associated with bacteria, and the environment they create around the implant called biofilm. Sources of contamination are usually the skin, the old implant, or remnants of the old capsule still in your body. Additionally, people who have occult infections like urinary tract infections can 'seed' the implants in your body with bacteria in your bloodstream after the surgery.
Every few years I have seen people like you come to my doorstep. If you have already had 4 surgeries (original plus 3 re-operations?), you have every right to call it quits; I usually tell people three strikes and you're out. However, if you are game for another surgery, you should be very thorough the next time, starting with possibly choosing another surgeon who is an expert in revision surgery.
I hope you can find happiness quickly. Best of luck.
