Helen -
not sure which Dr. Wiet you are referring to - the elder, Richard or the younger, Mark. Richard is a very well-known doc with an excellent reputation and great bed-side manner. He's been treating ANs - and other ear "problems" - for many, many years. In fact, he performed the first Cochlear Implant in Illinois. Richard is on the ANA's Medical Advisory Board and is (or was ?) an assistant professor @ Northwestern University's Medical School. Mark (actually R. Mark) is fairly new to the profession - not as experienced and doesn't have the same bedside manner as his father.
I am a patient of Richard Wiet's long-time medical partner, Dr. Robert Battista who is also an assistant professor @ Northwestern University's Medical School. Dr. Battista is in charge of training the new fellows for the practice (Ear Institute of Chicago) and he's in charge of the pediatric hearing program @ Hinsdale Hospital. He performed both my AN surgery (retrosigmoid approach) and my BAHA implant surgery.
If you're having your MRI in the new 3T machine @ Hinsdale Hospital it's amazing; they were setting it up when I was there in April for my 5 yr post op MRI.
Dizziness can be caused by an AN, but it can also be caused by lots of other things - and sometimes, no one can tell you what the dizziness is from.
My dad - just turned 83 this week - has had vertigo for several years. Despite being tested for numerous things, no doc can tell him the reason he is dizzy. In his case, the best the docs could do is give him a Rx for meclazine (not sure how that's spelled) to combat the vertigo and dizziness.
I'm hoping you'll get some answers next week. In the meantime, don't hesitate to PM or email me (my email address is in my profile).
Best,
Jan
