I was a b cup. I didn't want keyhole (I was too big as a b size anyway) as I have not been very impressed by the way the chest sits afterwards. It can end up looking like a boob that's had it's inards sucked out (looks like they have been popped). The specific surgeon that I had my surgery done with leaves some of the breast tissue behind in the higher end of the chest so it doesn't look "pigeon chested". The only thing is I will have to keep my eye out for lumps more than with sugery where they remove all of the breast tissue. I am happy with the contouring on my chest, will have to see how the scarring heals and get on my gym as soon as I am able. I have been told to wait for a month or so until the tightness eases.
Both my nipples were removed, the areola was made (much) smaller and the whole thing moved up 1cm. The surgeon said I because when I was younger i used to work out a bit it had stopped ny chest drooping so he only had to move it up 1cm. With larger breast sizes they may have to move them up more. The thing is with keyhole is i am not sure whether they do anything with the nipples or areola and female ones are usually bigger than males. My nipples were bigger than my partners and she's a DD cup. I haven't had them reduced as apparently they will shrink through the trauma of the op but it will remain to be seen, my areolas are now only about half the size they were pre op though.
