I'm having revision surgery next month with a lift, implant exchange (current 525mod+ saline) and going smaller. My chest wall diameter is 12cm, planning to go high/extra high profile in the Gel Xtra mentor implant. Doc suggested a 465cc silicon based on my measurements but I'm hoping to go significantly smaller with a 380. Doc hopes not to do a full anchor but if needed, will. Internal bra suggested? And implants hopefully stay put this time around with less weight/size.
