Jays,
Glad you found this place, sorry that you had to find this place.
To echo what many others are saying, your decisions have to be your decisions. I can relate to the difficulty you are having since my circumstances were very similiar. While I am willing to tell the path I took, please understand it is not in any way a recommendation or suggestion that you or anyone else take that same path.
I've had tinnitus and hearing lose for quite a while. It happens, you adapt, overcome, and move on. In November and December of 2007 I had 3 episodes of short duration volume increase in my tinnitus..as in for 30 seconds to a minute it got so loud as to drown out all other sounds. After the 3 episode (yes, I'm sometimes slow to take hints) I figured a trip to the audiologist was due.
Asymetrical hearing results got me referred to an ENT. Discussions with the ENT hammered out probably cause for the hearing loss asymetry but not the tinnitus goofiness. An MRI, just to rule out an extremely rare possibility of a tumor on the hearing nerve, which the long practicing ENT had only seen 2 of in his entire practice, was ordered. Seemed like a waste of good resources to me, but since it was promised to be painless, I agreed. End result was the discovery of a right side AN approx 8mm x 3mm and referral to another ENT that specialized in these types of things. This was all at Tripler Army Medical Center in Hawaii.
After a week the ENT surgeon contacted me...that was one looooong week... we met and the whole thing was explained to me, including the 3 options. Then I went off to make "The Decision". I'm very left brained...I like statistics, I like standards and lines drawn that reveal options when you cross them. The wonderful world of AN's has lots of statistics..often conflicting and always presented with lots of "exceptions". There don't seem to be any well drawn lines as to which option, given a specific size/location of the growth, is the best option.
Finding good info about best options was further complicated by my growth being so small compared to the size at discovery for a lot of other folks.
I pretty much went with the epithany theory of decision making... gather as much information as possible, get it into my head...then just let is swirl around while not thinking about it. Finding information was pretty easy (especially so after finding ANA). Getting that info into my head, not that difficult either. Not thinking about this thing in my head..pretty much impossible. In the end, I didn't really make the decision...my brain made it for me.
I went on a 3 day camp out with a bunch of friends on the President's Day long weekend. On Tuesday morning, upon settling in front of my computer for that first cup of coffee, I opened up my email program and had started typing out an email to my surgeon telling him I had decided to take the surgical route... As I typed the words I realized that I didn't remember actually making that decision. Upon a bit of reflection I realized that decision felt right...so I finished the email. The rational part of my brain presented it as ... it's not going to get smaller and you're not going to get younger.
End result, on May 13, 2008 I underwent a middle fossa route removal. One oddity that we spent some time verifying is that my AN was on the side where I had better hearing. Post surgical results... a bit of hearing loss, but my right ear still has better audiogram numbers than my left, some balance issues (not thinking a career change to circus tightrope walker is in my future), and "bugginess" in my right side facial nerve (I have full mobility back but do have the occasional oddity with the functioning).
One other oddity... mine turned out to not be a schwannoma but a meningioma (growth of the brain lining rather than on the actual nerve lining) but was placed such that it is considered an acoustic neuroma. The only difference is that apparently meningioma have a slightly less statistical probability of stopping growth than do schwannomas..make wait and watch a slightly statistically less good of an option (I warned you I liked things statistical).
Again, the foregoing should not be construed as a suggestion or recommendation. You have to make the decision that you can live with. Good luck.
... take care... tim b
