Facial nerve palsy: Clinical Practice and Cognitive Errors

Facial paralysis is the most common cranial nerve paralysis and the majority of these are idiopathic. Idiopathic facial paralysis, or Bell’s palsy, typically presents acutely, affects the entire face, may be associated with hyperacusis, decrease in lacrimation, salivation or dysgeusia, and typically resolves spontaneously. The diagnosis of idiopathic facial paralysis is made after a thorough history and physical examination to exclude alternative etiologies and follow-up to ensure recovery of facial function.
