Thanks to all who have shared their experiences. It has been very helpful and I just wanted to share my experience and journey so far. I had CyberKnife (CK) radiosurgery at Kaiser in South San Francisco couple of weeks ago.
I had a sudden loss of hearing one day to my right ear in March 2011. I was put on steroids for a few weeks before being diagnosed with AN after an MRI was performed. I have a 1.1cm x 0.7cm AN, which is considered small, so I had different treatment options, but radiosurgery sounded the best. It's a sight the first time you see the AN "lit up" on the MRI.
At first, I was glad that it was a benign tumor but my main concern was trying to figure out options on how to recover my hearing. It was a little disheartening to learn that trying to just
maintain your hearing was the best outcome as the hearing nerve is quite sensitive and that the loss is permanent. After reading through the treatment options and other side effects people had, I have come to accept the severe hearing loss and fortunate not to have many of the other symptoms of this condition (except minor fullness of ear and mild tinnitus). Still trying to adapt, and hoping the hearing doesn't deteriorate even further although it has during the past couple of months prior to CK.
It was great to find the ANA and this forum to hear people's stories and a support group with people with a similar condition. The other good source was Myacoustic.org, which had interviews with Dr. Steven Chang.

http://www.ncbi.nlm.nih.gov/pubmedKaiser referred me to consult with 3 neurosurgeons: Dr Tse (CyberKnife: machine arm moves) and Dr Efron (open surgery) in Redwood City and Dr Sahrakar in Sacramento (Gamma Knife: table moves). I was considering "wait and watch", but my hearing seemed to be deteriorating. All 3 neurosurgeons pretty much came to conclusion (including Dr Efron) that radiosurgery was probably the best option for me, but was great to have the multiple consultations and each seemed quite experienced in dealing with AN's. Dr. Tse was able to provide statistics as far as surgical outcomes for hearing preservation, tumor control, etc.
My treatment decision making process: My AN was relatively small; a non-invasive option seemed better than opening up my skull with a long recovery period, avoiding risk of facial weakness, and I'm trying to retain what hearing that I have. The statistics of the different outcomes seemed somewhat comparable with slight only differences between different radiology methods. My health insurance plan is with Kaiser and Redwood City/S. San Francisco are closer to where I live. Knowing the strong connection between Stanford and Kaiser was also reassuring.
A week before my CyberKnife surgery, I had both another MRI in Redwood City, a CT scan and fitted for a plastic mask in South San Francisco that holds the face in position during the procedure. I believe that the Kaiser - South San Francisco is the only Kaiser in N. CA with CyberKnife and I heard that they perform about ~2-3 AN's per week. Dr. Mellender was my radiation oncologist and also reviewed my case and consulted on what I should expect.
I had 3 doses of radiation (6Gy each) for ~40 minutes each over 3 days. The procedure is painless and feel almost nothing as you just lay there wearing the plastic mask as the Cyberknife moves around and you try to stay still. The machine notices any movements that you make and makes corrections. The machine's buzzing noise, knowing that radiation was going through you, made me a little nervous though. I just kept my eyes closed throughout. They suggest bringing music. Amazing that this is outpatient surgery and I felt no real difference immediately afterwards. Only immediate after effects have been slightly higher tinnitus and fullness of ear, but are deemed normal immediately after and subsided to prior levels. I could pretty much do anything immediately afterwards.
My experience with Kaiser has been pretty good. Although there are many specialists along the way, I've felt the care has been good, people have been friendly, and I've been informed along the way.
We'll see how the hearing progresses and will have another MRI done in a few months to see what has happened to the AN.
