Going to add this here rather than starting a new thread, in case it's helpful to anyone.
Dr. Y's office hasn't given me a final quote on everything, but in case you're thinking of going with him, here are a couple pointers on cost:
1) He recommended a company in Boston to do the CT Scan. The cost would have been right at $900. I decided to call around to hospitals back home (in the DC metro area) and found that Franklin Square Hospital in Baltimore would do the same scan for $65! So right off the bat, I saved over $800. It pays to shop around, because some hospitals will do a CT scan for a fraction of what other places will charge. He requires a CT scan (for me at least) from the chin through the orbital area, without contrast.
2) The cost for all of my procedures that he recommends (orbital rim implant, custom cheek implant, paranasal implant, angular jaw implant, and rhinoplasty) comes to about $20k. That's not including the fee to create the custom implant from the CT scan, which is about $5800, paid in advance.
Hope this information is helpful to someone who may be considering him. I'm still hoping someone will chime in with an opinion about Dr. Y! I've seen some reviews online that are really harsh about him (but I imagine you can find those kind of reviews with any doctor). And a lot of his online before and after examples are honestly less than remarkable. Sometimes I have a problem even seeing any difference, much less a notable aesthetic improvement, in his patients. Of course, not everyone allows their pictures to be posted publicly, so I've reached out to the office for some examples that are similar to my case. I'll see if they respond.
Any advice?? You guys know so much more than I do about this, so I would love to get some feedback, and happy to share photos in private.
