What causes unilateral paralysis of cranial nerve VII?
The etiology of facial nerve paralysis may be congenital, iatrogenic, or result from neoplasm, infection, trauma, or toxic exposure. In the emergency department, the most common cause of unilateral facial paralysis is Bell’s palsy, also known as idiopathic facial paralysis (IFP).
How do you test cranial nerve VII?
