Hello Al,
The recovery time can vary, but most physicians told me the smaller the tumor the shorter the expected recovery time. My tumor was a bit larger than yours, 1.2cm at my last MRI and 1.4cm at surgery, and my recovery was about 2 weeks. I define recovery as getting back to daily activities, driving, no pain, no drowsiness, etc. I felt I could have returned to work at 2 weeks as well, but played it safe by only working from home and going back into the office at 4 weeks. Most surgeons tell you to plan for 6-8 weeks though.
I also had balance issues prior to surgery. Mine was a lightheadness when walking that increased in severity when running or working out to the point where I felt I could pass out. At 2 weeks post-surgery my balance was better than pre-surgery and continued to improve. I am now nearly 8 weeks post surgery and I would say I am nearly close to normal. The balance nerve in the AN ear is cut with surgery, and as Michellef08 stated, it is better for your brain to learn how to use 1 fully functioning balance nerve rather than using both with 1 damaged nerve sending your brain mixed signals. It certainly has helped me.
I wish you the best with your decision and treatment.
