FWIW, seeing posts like these make me nervous but also likely more tolerant to such problems down the line. There's really not much you can do, right? So you're preparing people for the realities of this surgery and thank you for that.
But we're touching on a new point worth mentioning. Less work is better. Everything a surgeon does has real risks so you want him to be conservative. Ideally, you have a guy who has enough experience to understand how to balance the two since you don't want more surgeries either. I'm likely opting out of genioplasty, for example, because opinions vary on whether it's good aesthetically and I'm accustomed to it already but it's associated with numbness in the region.
Local guys tend to excel here because they don't have a lot of confidence in this area. Another advantage to them is they don't need to wing their surgeries either, they can actually practice models in advance. They can react more quickly to problems. The flip side is they know less so can't handle complex cases well. My opinion is to keep routine cases local and send only complex ones to experts. It's the same philosophy with all medical care really.
