I had one removed in September. Last summer I started having a lot of buzzing in my right ear and dizziness. I went to the Dr and he put me on some medicine which helped but I couldn't hear out of it. I went through several rounds of this and so he sent me to an ENT who found I lost over 80% of the hearing in that ear. He did an MRI and found the AN. I have been under the care of Dr. Babu at the MI Ear Institute who is the BEST for these. I had the surgery and am doing very good. I had a few problems following surgery relating to my baha hearing implant but otherwise good. 8 months out and I have traveled across the country multiple times, have been working and even wearing heels again. I still have some issues with the taste in my mouth. Just an fyi, I was not in great shape when I had the surgery having had 2 major back surgeries in the year and a half before. I am 48.
