Hi Brian,
I went back and read your previous posts to see what your symptoms were. Quite a few there, although I bet the hearing loss and balance issues/dizziness are the ones that stay with you.
First, yes. A Vestibular Schwannoma and Acoustic Neuroma are the same thing.
Second, many on this forum would call your AN "small but mighty". Sometimes small tumors are in just the right place to cause lots of symptoms. Do you have tinnitus? I missed that if you did mention it in a previous post. Even though I am SSD now after surgery, I continue with the loud tinnitus I had pre-surgery. I'm not sure if getting treatment earlier would have resulted in less tinnitus, but I didn't go see an ENT until my tinnitus was persistent and loud.
If your balance issues are mostly managable, you may want to consider one of the many radiation choices, especially if you still have good hearing. I think the doctor said it's good that the tumor was up against the ear bones because that keeps it away from the brain, and perhaps less interaction with the facial nerve.
As far as treating it earlier versus later...that's up to you. If it grows, and sometimes even if it doesn't, your symptoms will increase over time. You will lose more of your hearing, and if it begins to impact other nerves, you could eventually end up with numbness in the face and issues with taste. I think at this point you are not looking at big problems since we're talking about a tumor the size of a pimple
.
Nobody can chose for you, but you should do what you think will make you feel the most comfortable. Want it out? Get it taken out. Radiation ok for you? Get it zapped. If it doesn't bother you and the symptoms are not too bad, watch and wait will work for now.
IMPORTANT - If you decide on surgery, PLEASE make sure it is with a center/surgeon who has done LOTS of these in the past! Choosing an "in-network" surgeon who has only done a handful of these surgeries, or worse yet, none, could leave you with life-long facial palsy and other nasty effects. Do your research first, and rely heavily on the suggestions of others here on this forum.
Hope some of that helps,
Ernie
