So for a long time I was collecting videos from youtube with people who need/needed jaw surgery. You can watch my YouTube profile and see some playlists like "Jaw Surgery 1-2" or "Results", etc. Account - http://www.youtube.com/user/MrRaiden61/videos
But today I found a really big collection of videos here - http://mail.bracesinfo.com/videos/orthognathic-surgery/1/
There are about 50 pages of videos about jaw surgery. I know videos are very important for many people (like me) and they're really inspiring.
You can also go here http://mail.bracesinfo.com/videos.php and choose the type of surgery you are looking foor.
I hope that's will be useful. Best of luck.
