Ah okay, so you're saying the maxilla will move, it just will pivot in a rotation rather than move forward?
I'd expect nose widening of 1 to 2mm. Regarding upturning, that is harder to say. I've seen CCW cases with a lot of upturning and some with none. It's going to have to do with your anatomy (ans, tissue thickness, current nose droop, etc). I'd plan for at least a little change in that regard.
Kavan might be able to help on the plastic surgery question. That's out of my realm.
