Hi, I had a breast augmentation 7 years ago. Silicone 250cc implants under the muscle. Recently I've noticed one has dropped a significant amount lower. I had a scan to confirm that the implant is not ruptured. Is this a common for this to happen with implants and what is the cause? I spoke to a surgeon who wants to use mesh and just wondering what other surgeons thoughts are on this? I have attached a pic of what they look like now and what they looked like when I first had them done.
