Diagnosed with bellspalsy 11 years ago, now I have sykinisis. My eye closes when I smile. Will ptosis surgery help?

sorry to hear about your troubles. In thinking about how to help your problem, we have to understand what the problem is. For whatever reason, you have an aberrant 7th nerve connection so that when you smile, your eye closes. Eye closure (and most of smiling) is generally innervated by the 7th nerve, whereas eye opening is innervated mostly with the 3rd nerve. Therefore, unfortunately, ptosis surgery will unlikely do anything for your synkinesis since it is working on a totally different set of muscles innervated by a different set of nerves. You may want to think about carefully directed Botox to your eye closing muscles instead. 

When synkinesis develops after a facial nerve palsy the affected eye is smaller because it has excess stimulation of the closing muscle (orbicularis). Precise low dose botulinum toxin injection to block this excess stimulation works very well. Ptosis surgery would not be the answer. 



I would seek treatment with an ophthalmic plastic surgeon.
