Hi Stewie,
I'm also fairly new to the forum but not new to facial issues. I had a Facial Neuroma removed in 1992! The most important thing I can tell you is despite the fact that we wish the doctors new everything & the doctors wish they new everything, they just don't. The day before my surgery the doctor told me I wouldn't blink, my eye wouldn't close & I wouldn't drink from a straw. The day after my surgery my eye blinked when my other eye blinked, it closed (90%) when the other eye closed. When I was finally ready to eat and drink I tried to drink from a glass and the milk ran down my chin. I got frustrated and my husband suggested I try the straw, I told him the doctor said I couldn't use one, he told me to try it anyway, I did and it worked just fine. In fact, to this day I use a straw a lot as I have a bit of trouble with some of the water bottles we use while hiking. I think for the most part I use a straw whenever I can just because "I CAN"!
The doctors tell you what they think will or will not happen but they don't know for sure. I started to regain the use of the left side of my face 6 months after my surgery as the doctor thought I would. He told me my eye would water again within 2 years, it still doesn't. I can't tell you exactly when the improvement in my smile came about because I was to busy raising children and working to detect all the improvements. I do know that I noticed improvements over the YEARS as my face grew stronger from the use of the muscles and the other nerves taking over for the nerve that could no longer do the job. What I'm trying to tell you is DON'T give up hope because of what a doctor tells you. He may be wrong but if he's right you will be ok. I have a closed mouth smile too, I also have a husband of 30 years that loves me & a job that I got 3 years after my surgery. Good-luck, Jill
