Im not sure about revision. I visited another surgeon and he agreed that I was over advanced but he wouldn't bother with surgery again because of possible complications, and said that it would only be bringing back the jaws a couple mm so he thinks its not worth it.
Several people used to tell me I looked like Robert Pattinson, but my lower jaw was definitely recessed and I had a class 2 malocclusion. My jaws definitely didn't look like his. I guess it was more about the eyes, hair, nose, skin color...
My BMI is low, im skinny and have a normal neck. Just my jaw was recessed and my airway was too small.
