Acute Unilateral Seventh Nerve (Facial) Palsy
It is a traditional error in neurology to distinguish between central and peripheral seventh nerve palsy. Textbooks go to great pains to explain that the frontal muscles receive bilateral innervation, and that frowning is therefore still possible in “central facial paralysis.” There is some uncertainty about closure of the eye, and it is generally assumed that while the eyelids are wider in “central paralysis,” closure of the eye is preserved.
