Hi,
I'm sorry you have an Acoustic Neuroma, as it is a very complicated medical issue.
I would recommend watching doctors' educational videos from the ANA website. I used the videos to learn enough to ask important questions of different doctors. I consulted 7 MDs at 5 different institutions while I was in Watch and Wait for 2 years.
My tumor turned out to be growing quickly, compared to the normal growth rates, which meant, for me, that surgery was the better choice over radiation treatment.
I too had been afraid of poor surgical outcomes, generally, but then I decided to go to a hospital/program/surgeons who have a track record of great outcomes. With such a difficult surgery, it is important to have the best doctors. I was willing to travel very far, and had insurance that allowed me to. It turned out to be a great choice for me.
My surgery, at 65 yo, was very successful. You can look on this chatboard for more info from my other notes. It's 2 years now, after my surgery, and I have no regrets.
Wish you all the best in your decisions. Hope you can get a few consults with different MDs, who can review your history, MRI, and symptoms meaningfully and help you decide.
Best,
Skier
