I had Mentor Xtra silicone implants, size 435cc done 3/13/24. So only 5 months ago. Over the past few months my right implant slides laterally when I lie down (doesn’t have to be flat either). It doesn’t feel comfortable and it looks terrible. Not something I’d expect from new implants. I reached out to my surgeon and was told if it’s troublesome it would need surgical intervention, and he is retiring next week so I could go elsewhere. I’m beside myself.
