I am fairly new to this forum. I live in DFW and after a sudden partial hearing loss in September followed by an MRI, I discovered I had an AN (17mm x 10mm x 11mm). I considered options across the country before settling on UTSW, where I had surgery in December. I think I made the right choice. My surgeons were Dr. Mickey and Dr. Isaacson. Their bios are available on the UTSW faculty web site, but to gain a better appreciation for their knowledge, I recommend you meet them in person.
