HEI (House Ear Institute) is located in Los Angeles; HEI basically pioneered AN surgery. LA is a long way from Michigan, but people from all over the world go to House for surgery.
At the time I was diagnosed I had never heard of House, I was referred to a local neurotologist (Chicago area) by my ENT; so thankfully I had an excellent doctor right in my own backyard. Even if I had heard of House, it's highly doubtful I would have gone there - too long and expensive a trip, work and family obligations, etc.
My neurotologist is Dr. Robert Battista, Ear Institute of Chicago (
www.chicagoear); he practices with another excellent AN doctor Dr. Richard Wiet. Dr. Battista does both radiation and surgery, and he did my BAHA implant. He and Dr. Wiet also do CIs (Cochlear Implants); Dr. Wiet did the first CI in the state of Illinois. The Ear Institute of Chicago is certified by the ANA as a Center of Excellence.
You have some excellent doctors in Michigan - see the ANA's list. There's MEI (Michigan Ear Institute) and the U of MI has a facility. Off the top of my head Dr. Telian is a great doctor; there are more.
I love my BAHA (implanted March 2008) and fortunately it was paid for by my insurance company. They dragged their feet several months and I had to jump through a few hoops, but that was before Cochlear had an insurance division that helps BAHA candidates get insurance approval. It's my understanding that Oticon also has an insurance division now.
I recommend the BAHA is everyone who is SSD, but realize that it's not for everyone. Some don't want another surgery after their AN surgery - although the two surgeries are COMPLETELY different - and some are opposed to having a titanium rod implanted into their skull. While honestly that did give me pause initially, I decided it was a "non-issue" for me and opted for the surgery. I've never regretted it.
