I have been doing a lot of reading and maybe I misunderstood the radiation treatment??? I thought that there is a higher risk of fusing the facial nerve and vestibular nerve together
I haven't come across that anywhere.
if future surgery was needed patients are more likely to get damage and paralysis of facial nerve.
More likely?
No.
Radiation treatment has a very high success rate including preservation of hearing in many cases.
Here's an article that compares all three options: radiation, surgery, observation. What is important about this article is that it isn't a study in itself but a review of many studies by the top specialists in the field and involving many thousands of AN patients.
http://thejns.org/doi/pdf/10.3171/2012.6.FOCUS12192As for hearing loss, I knew I was developing hearing problems for a couple of years and thought it was just age. I procrastinated and one day (Dec 2011) I put the phone up to my right ear (I always used the left) and got the shock of my life. My friend on the other end sounded like a squeaky little far away mouse and the audiologist said that hearing in that ear was no longer "serviceable." Took a while to run through the hoops at the VA but I finally got my MRI in Apr 2012 revealing a 3mm x 4mm x 9mm AN. Since my hearing was mostly gone on that side and the tumor was small I agree to watch and wait with my next MRI scheduled for Oct 2012. At my Oct MRI the tumor had grown to 4mm x 5mm x 12mm (about 20% in 6 months) and when I put the phone up to my right ear there was nothing. Hearing on the AN side 100% gone.
My experience (and Rachel's) illustrate just how fast these insidious little buggers can do damage.
I'm not pushing any particular remedy. Radiation might be right for you. Surgery might be right for you. Depends on a lot of variables. And it's gotta be your decision.
But based on what I have learned in the past year, watch and wait should be more like watch and act.
