Since you are in Reno, you might want to consider checking out Barrow Neurological Institute in Phoenix. I live in the Phoenix area, so they were convenient for me, but I think I would've checked them out anyway, and I would definitely recommend them given my outcome. I am about 7 months post-op after having my 2.5 cm acoustic neuroma "de-bulked" using the retrosigmoid approach. I had experienced facial numbness, but had only a slight loss of hearing prior to surgery--due to the way my tumor grew. All of these are somewhat unique in size and location and the pre-treatment damage they cause, so as you can tell, one treatment doesn't fit all situations.
I was very lucky to be referred to Dr. Robert Spetzler at Barrow and he and Dr. Weisskopf, a neurotologist who is also fabulous, did my surgery. The size and location of mine was such that they did not feel gamma knife was a good option. The retrosigmoid approach was recommended as giving the best chance of saving the facial nerve and hearing--I didn't lose any additional hearing and my facial nerve is fine, too. I'll be following up with regular MRIs (just had my first one and it was as expected) and perhaps will need to have radiation at some point. I know it's a scary time, but the reality is that the options you have sound great and these people are fabulous at doing what they do. I can't say enough great things about my experience with these two specific wonderful doctors, and everyone at Barrow and St. Joseph's. I think you are right to take some time to figure out what feels best.
