I had a BSSO to correct my underbite 3 months ago and I believe that my maxilla should have been advanced as well. I feel like my upper set of teeth look pushed back and not far enough forward. I also feel when I talk they are not very prominent. I have prominent cheekbones on the outer sides of my fave but my midface looks flat. I just want to know if my maxilla is normal or not. My surgeon claims everything is normal my SNA angle is 82. I just want to know if my maxilla is normal.
