To understand the answer to this question, it really helps to understand the reasoning behind saying yes or no to your question. In theory, any time the skin is broken for any reason, including piercing your ears, there is the risk that bacteria that lives naturally on the skin could be introduced internally to your body (one of the skin's main functions is to act as an external barrier to bacteria and other organisms that can cause infection). If the bacteria enters your body then finds it's way into the blood stream, it could theoretically find its way to the surface of the breast implants and cause either an infection of the implants which could lead to their near-term removal or seed the surface with a small amount of bacteria which in theory could lead to hard scar tissue (capsular contracture). Thus, it is in your best interest not to be in a hurry to get your ears pierced and instead allow your body to heal completely from the breast augmentation. While no one is likely going to have a definitive answer on what "heal completely" means, I would suggest waiting at least 4-6 weeks before having your ears pierced. A little patience now could be worth thousands of dollars and countless hours of recovery in the future...it's always better safe than sorry. Best of luck with your continued recovery!
