245cc Mentor anatomical sub-muscular. I haven't been happy with this revision: more fullness in upper pole than my old implants and from what I specified. The right breast I could almost live with; is as big as my old implant, but still numb with an enlarged scar. Left breast is significantly bigger, I had no asymmetry with previous implants. Does it appear rotated? It is placed higher and the nipple hangs lower. My PS says is bigger because of swelling, could that be after 3 months? There is no pain or discomfort to back this up.
