Hi, so sorry you and your husband are going through such a hard time ,, it is quite an adjustment when the facial nerve is so impacted, however like Sara says,, you have to give it time to heal and that patience can be extremely hard to develop but you soon realize there is no rushing cranial nerve healing,, this is not like "regular" surgery that takes 6 weeks to recover from for most people . He had a large tumor removed ( mine was about 2.7 cm) and probably the facial nerve was stretched and must heal,, non medical opinion ,,, my facial nerve was severed so my situation is a little different,, however I was told 12-18 months for mine to regenerate,, his probably won't be that long, but you see the length of time it takes these nerves to respond,,, this is all just my experience /opinion ..
As far as eating, I agree that he will have to learn to eat again using the other side of his mouth,, small bites and soft foods that don't require much chewing for awhile. A straw will become his best friend for drinking ,, I bought them by the box for months,, I had to cut everything up in very small pieces and place it in my mouth,, no biting off a sandwich or burger etc. I also lost 30 lbs the first few months but as he learns to eat he should gain some of that back,, right now just getting something in him is important ,, pudding, oatmeal , rice and gravy, scrambled eggs,, he will just eat very slowly and deliberately too so as not to choke,,
It's a hard time of year also to be dealing with all of this ,, I know as I had my surgery in Oct. 2011, and was not anticipating the Holidays with facial paralysis in addition to brain surgery recovery,, try to encourage him to be patient, rest and try to heal knowing it is going to take time for his brain to re-learn and recover,,, it will get better! We are all here to help with non medical advice and encouragement ,, give it some time and he will see improvements ,, I am sure,, take care and best wishes to you both,, let us hear from you ,, we want to help if we can,,, Jane
