your asymmetry is completely normal. 2mm is nothing.
OK, I didn't measure it exactly, but it's significant! You can see quite clearly that my chin and lips are different on both sides and that my entire lower face isn't symmetric, and I have a cross bite...oh, and to add a little fun to the mix my eyes are different colours too
My nose is asymmetric as it's never been the same after the kickboxing accident I had. I was hoping that it would be straighter after the rhino but unfortunately it's still off-center. Maybe I slept on my side too soon or something....
Anyway, jaw surgery won't fix that issue, I have to live with the squinty nose
The dentist I spoke to today had done a decent amount of maxfac rotation and he told me that if I were not non-resident I'd very likely to be able to get at least a BSSO on the NHS. That surprised me. If it's bad enough that the NHS would cover the surgery then I think my parents aren't going to object as much.
I am not worried about the pain of the surgery, TBH. I had the original kickboxing nose-break (anaesthetic and painkiller free, obviously!...)and then the septo- rhino so I kindof know what recovery will be like. Jaw surgery will be worse in terms of swelling, duration, total area and eating but I know what the sensations, congestion, not sleeping etc. will feel like.
My body has inflicted far more intense pain and unpleasantness on me naturally than I have ever experienced via a surgical procedure anyway. Also, you don't know pain until you've tried threading your upper lip
