I had my first BA consultation this week and scheduled my surgery for 3 weeks from now. My surgeon recommended MemoryShape for me and I chose the 495cc high profile as I did not want to go any smaller. I really like how the fullness of a round implant looks over the more natural MemoryShape. I really feel like I'd like to have the MemoryGel Siltex high profile 500cc implants. The diameter is only 13.2cm so they are no wider than the MemoryShape 495cc. Would this switch work?
