My surgeon said that my nose would widen and tip up a little and that the widening would be exaggerated the first few months until the swelling went down. He said that since my upper palate is widening, and therefore my face is going to be wider, that it was good to have my nose widen a little since it would look strange to have a thin nose in a wide face. My nose, as it is now, is really small.
I have to admit that I'm a little nervous about this. I've always liked my nose, but if having a wider nose means having a healthy, pain-free bite, then it will be worth it.
