Just an update...
I've been in braces for about 5 months. I talked with the surgeon again today since I'm still deciding on surgery. I feel like I got quite a bit more information this time around.
Lower jaw - The asymmetry of the lower jaw is obviously my main issue. From what I understand, he would move the long side back about 7 mm which would rotate my chin to center. Other side would be moved back more like 2-3 mm.
Upper jaw - I asked about the upper jaw since I have a cant, and also some downward growth/gumminess. The surgeon agreed on both counts, but said both issues are so small that it is not absolutely necessary to do upper jaw surgery. He said my cant is less than 2 mm. If we did the upper jaw, he would correct the cant and impact 1-2 mm for the gumminess.
Interesting news about the gumminess. He said I have a hyperactive upper lip. (Aha!) It makes me show a lot of gum, over 4 mm when I smile really big. If I don't do upper jaw surgery, I could calm down the hyperactive lip with botox. (I may do the lip botox soon and see what I think.)
A couple of pics below from the front to show the asymmetry. Last two pics show the gummy smile, and the last one also shows the hyperactive upper lip in action.
I'm leaning towards surgery, at least for the lower jaw. Upper jaw... I'll need to think on that one. Might as well fix all of it?
