The cranial nerve is 7 or 8. My tongue tip and side had transitory changes because the tumor had splayed out the facial nerve. My facial nerve wasn't cut; it will heal slowly. The dry mouth is related to the facial nerve numbness. Dry mouth can appear and disappear. It heals soooo slowly. My eye, eye lid, nasal fold, tongue, lip curl, and cheek were temporarily affected. My side temple, and eye brow arch hurt in the beginning. Then I had eye dryness, eyelid droop, lip curl, lip twitches, and tongue/taste issues. Everything has cleared up over the months, except some residual numbness in the tongue. The timing and the sequence of appearance of symptoms, and healing seems to be different for many people. I was only diagnosed with facial weakness and with late onset of symptoms. My doctor expects all of this to recover since my facial nerve, smile, grimmace, and eyelid were working immediately post op. Symtoms didn't start appearing until day 10. I can't complain about any of my symptoms. I am happy with the results I have. I am so pleased with the way my nuerosurgeons took care of me. At age 64 I was risking so much more loss than facial movement.
