Hi Unjaded,
I had my AN surgery Oct 2011, my facial nerve was also severed. I did not have the tube you spoke of as the Dr was able to save enough to butt both ends up together . It took about 6 months before I saw any real movement, the Dr had said on discharge that it takes nerves 12-18 mos to regenerate,, and at 12 mo visit, he was "happy" with results ,, so give it some time and try to be patient,, which is easier said than done I know, I now am able to drink without a straw most of the time, except hot coffee,, still don't chew on that side as swallowing is not too good,, forgot to say I had the 12-7 nerve graft, so he connected facial nerve to tongue,,,, yeah, it's awkward at times,,
Hope this helps some,,, I am willing to bet you will have good results too within about 6mo. You will see small movement on that side almost weekly/ daily,,, let us know how you do and best wishes for much success ,, I did not do any training or actual exercises per se, just massaged cheek and tried not to tighten eye too much to avoid synkenisis,, will look forward to your posts ,,, Jane
