I went in for some post-operative x-rays today. I, of course, had very little idea what to look for. I was able to locate the titanium without any trouble. I even found my braces ;-)
But the radiologist (or whoever took the x-rays; she may have had some other degree) said that the surgery was a very good one. She specifically pointed out a straight mid-line and said that my chin looked nice. I still can't see it very well because of the swelling. I hope that I'll get to compare the new to the old ones.
Anyway, it's great news - I sure would hate to have to have the surgery re-done, and it looks like that won't be an issue.
