I just like to get peoples opinions on this.
Say if I can't get a lefort III, would It better to keep my retrognathic profile (class II) or get a lefort I/BSSO to have a normal profile but risk having a flatter looking mid-face?
Well strictly speaking you would need a Le Fort I regardless, since your bite is messed up. While it is possible to correct the bite with an LFIII, it has a very limited range of movements. So it would have to be a combined: modified LFIII + LFI. The main problem with LFI is not that the mid face ends up being flat, but the opposite - a protrusive lower part of the mid face giving a chimp look if the upper part is still recessed.
I don't think you have very recessed orbits. LFI can still improve the way your under eye area looks. It does not touch the orbital area obviously, only tents up the the muscles somewhat. But it helps in the same way chin augmentation is like a free nose job in profile, if that makes sense.
