Wow madonal1, that's a tough situation. A lot depends on a number of factors, like the position of your tumor. It was suggested to me to get at least two more opinions and to seek out surgeons at a teaching hospital with a lot of experience. The surgeons should be able to provide you with statistics on how well they do concerning facial paralysis for your type of tumor. I sent my MRI to two different docs and I was put as ease when they all had the same opinion. Doing homework on your diagnosis, doctors and hospital will help you to feel informed. It definitely worked for me.
I have facial paralysis, but I have been told it will probably heal but it could take as long as two years or, of course, it may not heal. At times it's tough, but I did what it takes for my family to keep on seeing my face, goofy or not--alive. I have noticed that it's my family who looks at me differently: With more kindness, love and gratitude. My family just sees me when they look at me and I'm grateful for that.
Honestly, the face thing isn't the hardest part of recovery for me but because it's the only one that's visible it's something with which to contend. I kind of think the body does this so that there is a visible sign that I may need some special handling now-and-then.
Inform yourself and your decision will be made with confidence and courage. I'll be watching journey and keep you in my heart.
