Hi Joana,
I am 5 years post op with about 85% recovery of facial nerve. I developed synkinesis at about a year and at 2 years, went to see Jackie Diels at U of WI for 3 days of intensive facial therapy. I have since seen her several more times and have gotten very good results from my work with her. I tried botox for the first time last spring, under her supervision. Although I did see some improvement, when the botox wears off (for me, about 6-8 months) things go back to where they were pre-botox. So, I probably won't do it again (partly because I don't want to fight with my insurance company.) That said, I did find that the injections in my neck really did help (short term) with the pain and tightness in my face. And that irritating chin-dimple went away completely until the shots wore off.
Feel free to PM me if you want to ask more questions, or if you want to chat.
