Not so much a cost, although it is a factor, but cranio-facial surgery means bone work, and 90% of the surgery is focused on bone remodel. He will not attempt, nor should any surgeon, attempt to do any soft tissue work since as soom as skin is cut into it swells and becomes not proportional. Any attempt at soft tissue work other then forehead and that is simply because of forehead advancement due to the cut necessary for forehead remodel, will result in bad effect.
A lot is in the character of the surgeon, Lazaro is one who will push the envelope only so much, and not take away more then he can put back. In other words, he will stop short of critical, it is safe, and as he puts it him self, you can always go back and take away another 2 mm however to ad 2mm when they are gone is way more complicated.
He guarantees the results so that you will be satisfied, if after nose job you want another 2mm further reduction, and if your bone will allow it, he will do the surgery for free except hospital pay. That is rather unheard of in this FFS industry.
Anyway, from your reply it seems that perhaps you would be better of with some other surgeons in the US, they work more in the American style of medicine. 🙂 Good luck!
