on what sides can facial paralzsis occur?
what does a lower motor lesion to in the facial musculature?

what does a lower motor lesion to in the facial musculature?
what can damage to facial nerve cause?
the internal acoustic meatus (by a tumour),
in the middle ear (by infection or surgery),
facial nerve canal (Bell’s palsy),
in the parotid gland (tumour)
through laceration or injury to
the face.
drooping of the lower eyelid and the angle of the mouth.
paralysis of the orbicularis oculi muscle leading to incomplete eyelid closure during both voluntary and reflex movements.
Eyelid closure is the means by which the cornea is lubricated; functional deficits in the ability to close the
eyelid can therefore lead to corneal damage and permanent vision impairment.
