you know who does it? probs crazy dangerous right?
It isn't something one can just stroll in and get 'done' - it takes a team of craniofacial, maxfac, neurology, and neuroanesthesiology surgeons to perform. Complication rate is surprisingly low; something <5%, as I recall. Of course, those complications aren't pretty. You definitely don't want enopthalmos, although blindness is - again, surprisingly enough - very rare. Aesthetic results are natural-looking, from what I've seen, although it can be difficult to properly gauge given the starting points of the people having the operation. There are a few different surgical techniques, ranging from the mildly nauseating to the downright horrifying (facial bipartition).
Unfortunately, I doubt any western surgeon would even consider it for anything less severe than an IPD >2 SD below average. Let me know if you do ever ask any surgeons about it, though.
