Experience is critical. But, doing a couple of AN's a month is A LOT. I see repeatedly claims of "thousands" of procedures etc being thrown around and I'll say this: I don't believe them. There are not enough AN's in this country to support some of the claims I see posted about "my doctor".
I'm not talking about the Dr and number you referenced. What I am saying is that my Dr told me he does 2 or 3 a month and that that is a lot. 500 a year would be roughly 20% of all AN's diagnosed in the entire nation. Think about how likely it is that that would be the case. Think about the likelihood of one Dr performing 2 such procedures a day, 5 days a week, for an entire year.
If a neurotologist does 30 AN procedures a year, along with cochlear implants, all the other kinds of delicate surgeries that they do, along with research, teaching, and in-service training, along with publishing and report writing, never mind that they go on vacation and play golf too, it is a lot of AN's.
There are many Drs. in the USA that do these procedures regularly and with good results that are completely unheard of on this forum. This forum is comprised of basically a handful of people who have AN's. There are thousands of people with AN's who have had treatment that have never registered with this board and you wouldn't hear of their positive experiences with Drs. never, or rarely mentioned on here. My Dr is a good example. Search "David M. Kaylie" on here and other than my posts, you will find very little mention of him. I think Clarice is the only other member to have experience with him. Yet, he is a premier provider in this field who even patented a device for monitoring the facial nerve during these surgeries and he works out of a facility that people like Ted Kennedy and Preston Robert Tish, millionaires who could have gone anywhere, went to.
I've never been to Michigan, much less researched AN treatment providers there. But, my guess is that there are some very good neurotologists who who practice in Michigan who very likely got their training by working under people like Dr. Chiang. In fact, I would contact him, as well as other well known Drs. in this field and ask them who they may have trained that practice in Michigan. Call House Clinic, and others and see what Drs who used to be there are now in Michigan.
Here is an example of what I mean. A good friend of mine is a highly regarded plastic surgeon who specializes in facial nerve reconstruction. He trained at Duke and Johns Hopkins. He has all the experience and training and reputation of a "superstar" in this field. He laughingly told me about how when he lived and practiced in upstate NY, people didn't understand that he was still a premier guy in his field. In other words, if someone in Buffalo NY had a disfiguring facial trauma, they would be looking right past him trying to find a "good" surgeon somewhere else.
