This might help some. My tumor was very sticky. Although it was 2cm, it took nine hours to get the bits unstuck from the facial nerve. I had excellent conduction post op and for 9 days . But then on day 10 I experienced "late onset paralysis", that is, the eyelid, forehead crease, eyebrow lift, nose wrinlkle, lip curl, pucker, smile curvature, and cheek lift ceased. Numbness issues persisted for the next three weeks. Then slowly the parts started moving. By the end of two months most of the movement was back.   ÂÂ
But, then my tongue started to burn. Actually it too had been numb on its side and I wasn't aware. Today (at 6½ months out), I am still recovering from the tongue numbness and sore spots that come and go on my forehead and lip. Mosts foods taste good but I try to keep my tongue still in there, not wanting it to explore my teeth too much, because that starts up the sore spots again on the tip of it. My doctor predicts that 9 months will see the end of tongue problems too. So far, he's been right. So if you develop "late onset paralysis" hang in there. The only "cure" I used was eye lube, warm compresses, Biotene toothpaste, slow chewing, and very gentle massage with my palms.
