Hi!
I don't know if I can offer you any insights but can tell you what I have experienced. I had the 12/7 a year after my initial AN surgery since they said that the nerves will only heal for one year. That surgery didn't have the results that I had hoped for but at least it hooked up a "live" nerve to the one that obviously wasn't working - so no major movement but at least it wasn't "dead & droopy" anymore. After I joined this Forum, I learned from Nancy about the Temporalis Tendon Transfer (T3) done by Dr Patrick Byrne at Johns Hopkins in Baltimore. At first, I was very doubtful because it was YEARS after my surgery (12, I think) but this surgery involves the tendons and muscles in your face (& they took tendon from my leg to lengthen) NOT NERVES so there is no time restraints. I had it done in the spring of 2008 and even though I had a LOT of complications (NOT the norm, just me!), I was able to see almost immediate results. In theory, this surgery just would allow me to have a closed mouth, "Mona Lisa" smile when I clenched down. In the fall of 2010, I realized that I was able to move my mouth into a closed smile WITHOUT clenching and then just this past week, realized that I could actually do an open mouthed "grin" - on the exact date of my initial AN surgery 17 years ago!! Of course, it is still not perfect and I still have a crazy eye but YES, YOU CAN GET YOUR SMILE BACK - at least I have. I don't really know if it was the T3 or what - I know that I am a strong believer and am giving God all the glory - to me it is a miracle - whether it just finally happened after all this time or is a result of the surgery - it doesn't matter, both were because of God!
Please let me know if I can answer any other questions!
