I had my AN surgery 8 years ago today actually,, my facial nerve was severed as the tumor was intertwined with the nerve. So I had the 12/7 nerve graft 4 days later.
I did not have any sort of therapy afterwards,, it may have been helpful though if available. I had good results I believe. At resting you can not tell I have paralysis. I have good muscle tone on that side of my face which is really the main goal of this graft I believe. Without the graft the face would droop. When I talk the corner of my mouth does not open fully so I speak “ like a pirate “ I always say,,, I do not have a full smile. But there are other surgeries to recover your smile. This graft helped my eye to close better. I did have a weight placed in my eyelid for almost a year because it wouldn’t close correctly,, but that was removed.
I was told to expect improvements for 12-18 months. I believe it was around 6 months that I saw the first movement. It will be slow to you but have patience,, it will happen. You don’t want to try to “ force” movement too early..then you may encounter involuntary twitching known as synkinesis. It will happen in time. I seem to remember experiencing subtle changes even after 18 months.
All in all I am glad I had the graft ( would have preferred NOT needing it but,,,) and believe I have good results. I do have some Botox shots done several times a year to ease some twitching around my eye. BUT I did not start that until years after graft.
Good luck to you,,, I hope this has helped a little,,
