I have the same functional issue as you, I also have a cross bite which I am going to go through surgery for, mainly for functional reasons as I am currently ok with the way I look. However my main issue with my face is my smile and recessed maxilla which make me look older too if my face is totally relaxed. Did you have a consultation with a surgeon yet? I highly suggest getting one, even if you decide not to go through because I discovered a whole lot of other issues I never even knew of when I went in for my consult! I know exactly what you mean by one side being weaker, I have that too as well as the asymmetry. I hope some of it gets corrected by jaw surgery, however jaw surgery is not perfect, and people like us who are pretty normal looking don't have much to gain by it aesthetically. I mean, for functional reasons yes. But looks wise there's always more to lose. I'm not too worried because I think it will be a positive change for me aesthetically because of the movements being made and the fact that I have confidence that Dr.G has the utmost ability to bring out the best results. Anyways, get a consult. In my opinion, men who do lefort 1 have more to lose. I saw some pretty horrible results in men, kind of feminizes the face by making your bottom jaw less prominent. But like I said, your movements of 2/3mm are very small. Hard to tell. And besides you'd have to pull your wisdoms first. If you can I would highly recommend Dr Gunson, the consult fee is only $250.
