Hi Denise,
I had my surgery 3 months ago. I went the Mid Fossa route and my hearing was preserved, despite it being pushed up against my cochlea. I had absolutely resolved that I would wake up from surgery with single sided deafness. Boy was I surprised when I could hear! If I hadn't had the surgery, my hearing would have continued to fail in that ear, so I am definitely grateful for it being preserved.
The surgery itself is, well, brain surgery. I was in hospital for 5 days, including my surgery date. You will hear from other post surgery folks (posties as we're called) that the first three days after surgery are the most challenging and you just have to get through them. After that, recovery happened relatively quickly. I remember feeling that every day I felt 50% better. Of course there is a plateau here and there, but I'm almost back to normal. I do still get tired and have to nap. :-) And I continue to go to Physical Therapy to get my balance 100% better (I'm at about 85% right now).
I will say that, the surgery was worth it for me. In many ways I feel more clear headed and better focused. I was having terrible bouts of vertigo while the tumor was there and I feel much better. Occasionally I get a headache, but Tylenol takes care of it in a jiff.
Keep posting and you will hear lots of stories of people's experiences with this. Keep in touch.
Miss Molly
