My baby is suffering from facial nerve palsy due to birth trauma (as she cannot close her one eye and move her lip of left side while crying) please help?

Complex: If this is a rather recent birth, there may be spontaneous resolution within the next 6-8 weeks, but if this has been chronic, likely best to see a pediatric neurosurgeon, and discuss management. There may be some remote benefit to some medications and perhaps vitamin b-1, thiamine, and even less potential with steroids, but might be worth checking into.
