Welcome to the group, annette​. There have been some women who've had issues with their implants from 20+ years ago ... it's good that you've not had those issues!
So, after the removals, you'd still like to have something done to give you curves again? Have you spoken to your surgeon about alternative implants? Or are you considering using 'external' prosthesis or preferring a surgical procedure again?
I'd suggest you join the Breast Reconstruction group and put your questions there as well.
