A rule of thumb is that what function you have on waking from surgery is what you will have later on. Were you on a tapered dosing of decadron or other steroid following release from the hospital? Often times, the steroid does it job of preventing swelling and inflammation of the cranial nerves affected by the surgery while you are taking it, but when the steroid dose is over, delayed complications of surgery can set in. This happened to me, my facial function went to HB2 from 1, my vocal cord stopped working, and I could not swallow on the AN side. With time the functions returned but it take 16 months to recover considerably an at three years plus from surgery I am almost normal in all respects.
Delayed complications are common and mostly require patience as the nerves recover and function gradually returns. Good luck.
