I have nerve damage in the left side of my face from a traumatic case of bells palsy (which is SUPPOSED to be temporary... I've had the after-efffects for five years now).
It took much longer for my nerves there to begin functioning again and I still have troubles with it. It's such an odd feeling... to have the nerves in one side of your face going nuts!
Contact Dr. Waner's office, though. You can certainly revisit the issue of surgery. There's no harm in talking about it. You can also email Dr Levitin though the site, if you haven't already:
