Hi Liz,
I had a middle fossa approach 14 months ago. There isn't much you can prepare for, but here is what you might expect post recovery. The first few days can be very challenging as your brain tries to calibrate itself. Don't worry, the really hard stuff lasts a few days, after that it takes a lot of time for healing. Unfortunately, there is no bench mark to go by, like if a person breaks a leg, the medical community can give pretty good estimates of recovery. Surgeries concerning the nerves are very delicate and each person has there own specific recovery. I was very discouraged in the beginning, I expected to be up and about in a few months, my recovery took a real long time. The second symptom you might have, which seems to affect many middle fossa surgeries is fatigue. You will tire quickly, I always say to other AN patients, listen to your body, and take a nap if you need one.
I hope my comments help, and I wish you the very best recovery, please keep your AN friends up to date on how things are going.
God Bless !
