I had my AN removed in July of 2004. I had a translab. for 2.5cm tumor. After surgery, I had no movement and was told I would regain movement, my facial nerve was intact. I started to regain movement about 6 months following surgery. It started out as a little sensation/twitch around my naso-labial fold (crease in area next to nose). I was not able to blink following surgery and my blink came back about the same time. It was a gradual process. At rest, you don't notice a difference, but when I smile, you can see I have some weakness around my lips on my AN side. My blink is not as quick as my good eye, but at least I can blink and close my eye when I sleep.
Just hang in there and be positive. I too, was very frustrated after surgery, because I had no movement. Another thought is to find an occupational therapist to work with. They may be able to give you some advice and therapy to help regain movement.
