Lisa,
Your tumor was large and in this range those with large tumors do have a higher risk of facial paralysis and other complications, doctors are now in agreement that facial paralysis increases greatly in those with tumors 1.5 to 2 CM in size. These AN's are pesky little so and so's, and located in a very delicate area of the head making the surgery difficult. The post op issues are even more difficult to accept if you have been told by your doctors you will be fine in no time. Some doctors give you the impression that because these tumors are usually benign, the surgery is no big deal. The post op issues need to be explained better by the doctors to those whose tumors are large and need to be surgically removed, they need to be more attentive to their patients symptoms.
It is scary when you realise you won't be getting back to the normal you had known. We have a "new normal" to get used to post treatment and some more than others. I hope you will gain more movement, balance, and peace in your life as you continue to push yourself through your rehab exercises. You have much to deal with and I hope you have loved ones around to help you cope.
