Welcome? Very sorry you are going through this, but you aren't alone.
Your tumor is in the "small" range and I am wondering if your doctor offered you "Wait and Watch" as an option? Also radiation treatment is the other form of treatment. If you do not have debilitating symptoms, ie: severe balance issues, nausea, headaches, facial nerve palsy/weakness, "W&W" is a good thing to consider as these tumors tend to stop growing for a while or grow very slowly.
The recovery from surgery can be somewhere between 6 weeks to one year. Some people have debilitating headaches after one year. One doesn't know how they will heal, but the majority recover within 6 weeks and back to work shortly thereafter. Regaining balance and learning to walk, spin around, move your head side to side will be your challenge and vestibular re-training therapy is a must after surgery. Also many people suffer from "brain drain" and find themselves in an exhausted state just doing the most simple of tasks. There is much going on for the brain to assimilate; eye focus, brain processesing all incoming stimulation and body balancing itself, is exhausting. Some discover they are deaf on the operated side and this is a learning curve in itself, but one that is easily overcome.
Your wife will be faced with her own set of challenges too. There is a new category to this site for the "Caregivers" and can be helpful to her. My recovery was helped along by my husband's patience (I was impatient and grumpy) and prodding (had to get up and perform exercises every hour on the hour for 6 weeks straight) to get my balance back. He had to learn to deal with my deafness, no talking from another room, no talking to me while I'm on the phone, trying to remember what side is my good side when in public so I can hear him better in stores, restaurants, keeping his mustache trimmed (he still is lazy about this) so I can see his lips moving (I learned to read lips), speaking clearly and slow, etc. This was a huge learning curve for him and frustrating time for me--lots of sighing on my part.
If your facial nerve is involved you may discover your taste is alterted for a short period of time, my taste came back after 6 weeks. I still have, on some days, numbness at the tip of my tongue, metal taste in my mouth or can't taste much. This comes and goes and I'm used to it, doesn't bother me much.
