Hi sorry for your difficulties.. I had my facial nerve cut and grafted with the 12/7 anastomosis last Oct. 2011, I was told I would see some facial movement after about 6 mo but that full regeneration would take 12-18 mo. I have seen movement in my facial area at 10 mo mostly in some smile improvement, I can drink without a straw all the time and at rest my face looks almost "normal"... a test was done few months ago to determine that graft 'took" so improvements should continue.
I am not sure why Dr. told you it should be that long for yours to "heal' if it is still intact.. seems like it would be shorter timeframe for it to strengthen than if it was cut.. but I am not a Dr.
I don't have much more advice as far as your surgery options, unfortunately. I do have the eyelid weight already and that helps eyelids meet so I don't have too much dry eye or cornea issues. I use eyedrops at night to help.. I do have lose of facial muscle tone also but not to degree that it is hurting eye closure I don't believe, maybe due to eyelid weight..
Have you tried massaging your face/ cheek area intermittently? I find that helps with tightness and pain and general circulation..also "make faces" at yourself and try to re-train those muscles and nerves.. I have not had any formal facial training yet but try to make it move on my own..
Hope any of this helps,, not sure what I would do about surgery if I was you,, sounds like you are getting such conflicting advice from your Drs... unreal... good luck to you,, I do hope it starts to improve for you, , keep us informed as we do care and some others with facial issues will probably chime in...
