Gunson is worth seeing even if you don't plan to have surgery with him because their consultations are so good, thorough and informative. Wolford is a jaw surgery god, but he's obsessed with TJR, which means he's not the right surgeon for a lot people. His consultations are also more expensive than Gunson's, so I'm not sure it's worth it since the actual surgical plan will be very similar. Sinn is not comparable to these two. I'd only see him if you need some rare cranio stuff like a modified LeFort 3.
