in germany if you want to be a malox... surgeon you have to study medicine and over the top you have to study dental medicine so two faculties. I was at one of the best surgeons nationwide. prof. dr. dr. al-nawas chief doc at the mall..clinic of the university of mainz. btw both docs knew about my hawmophilia
I'm fully aware of the fact that maxillofacial surgeons have double degrees. That's pretty much the case almost everywhere for the last 30 years. And even so, 90% of the time they do dental implants and pull wisdom teeth. Being a faculty member, writing 100s of papers means NOTHING. FWIW, I think I found the publication profile of the surgeon you mentioned. He has 100s of papers on implants and oral cancer, almost nothing on orthognathic surgery. But scientific interests don't mean anything anyway. I consulted with the head of the orthognathic surgery department of the local university (top 20 world-wide). He asked me why I chose to consult with him. I said because he's the head of the department. He said "IT MEANS NOTHING. I COULD BE JUST AN ACADEMIC. THE ONLY THING THAT MATTERS IS VOLUME OF WORK AND RESULTS".
tldr;
Consult with Zarrinbal without pre-alerting him of your haemophiliac status if possible. But do pop the question at the end.
P.S.
After my Le Fort I surgery the surgeon said I had "a lot of vascularity" in my upper jaw, so everything will heal well (you need good blood supply to the jaw after it's been mobilised). Someone here told me that that's a code word for "bled like a stuck pig". The nurse gave me a bag to spit blood into - the stitches inside the mouth bleed for a while. I was told to throw up in it if I feel sick and "trust me, everyone swallows a ton of blood after this surgery and vomits" (I didn't end up vomiting, my stomach must like blood). So perhaps Le Fort surgery does cause a lot of bleeding.
