I experienced facial paralysis after retrosigmoid surgery. My doctor seemed shocked because it was functioning during the operation too, but didn't respond at all in the hospital. I think the first thing I noticed is my face started to fill out in the temple area at about 6-8 weeks, where it had become rather concave in the weeks following surgery. Then there were the slightest movements on my cheekbone near my ear and next to my nose at around 4 months. Then the ball of my cheek would ever so slightly pump up with a slight raise of the corner of my lip around 6 months. I think all of these things happen naturally over time and shouldn't be pushed. Just my opinion, but try to use natural facial expressions and don't exaggerrate or try to hold them for a long time. I started seeing a facial therapist early on--maybe 1 month post-op, who recommended strengthening exercises for those muscles showing any movement. After 6 months, the synkinesis kicked in. I'm not saying it would or would not have happened if I had done nothing, but I don't think it would hurt to wait for up to a year and see what regenerates on its own. I know it's hard! I am now at 1 year, 2 mos post-op, and my face is kind of in a constant smirk on that side with synkinesis in my eye, eyebrow, cheek, neck...I have an appt with Jackie Diels next month and I hope she can help! Best of luck to you, and keep us posted on your progress.
