Hi, thanks for replying! I think there's a difference between being disfigured and unable to chew compared to cases of not liking your result because it isn't as dramatic or as natural as you hoped. After all, everyone wants different outcomes and someone might be unhappy with their result because it isn't as dramatic as they wanted whereas another person with the same result might be extremely pleased.
Also, I did research and talked to a lot of different oral maxillofacial surgeons and most of the time, when it comes to not being able to CHEW properly/having a bad bite after surgery, it's because of the orthodontics, not the surgery itself. That's why your orthodontist and your surgeon have to communicate and come up with a proper treatment plan in order to effectively correct your bite.
