Prinewill, I am more than 6 years past surgery for a similarly large tumor and still have some issues. I am a little over a year from Gamma Knife treatment for regrowth of the tumor, and its complications, which are still with me. Cranial nerve function can return with time, and what does not return we seem to adjust to. My vocal cord is still impaired, but I can speak and project my voice, that took over a year after surgery. I had facial paralysis after both microsurgery and radiation. The facial weakness is improved but still present. My eye still does not close completely and the corner of my mouth is still weak. My eye is more narrow than the unaffected one. I developed synkinesis, involuntary muscle movement in my face which is a real problem for me, but very few people actually notice it. You need to give yourself time to see if your nerve heals and to what degree. There are medical options to restore what does not come back, though I am not certain what is available in your country or even on your continent. Your surgeon should be able to guide you in finding how to deal with your issues. How have his previous patients dealt with them? You will find people here who have dealt with the same complications you are now experiencing and can relate to your feelings very well.
It is difficult to answer all questions in one reply and address the negatives you feel now, but keep coming back and you will hopefully find the interaction a helpful process. Things do usually get better, many people improve with time and effort. You should too. Good luck
