Facial paralysis is the most common cranial nerve paralysis and the majority of these are idiopathic. Idiopathic facial nerve paralysis, or Bell palsy, typically presents acutely, affects the entire face, may be associated with hyperacusis, a 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. Atypical presentation, recurrent paralysis, additional neurologic deficits, lack of facial recovery in 2-3 months, or a his tory of head and neck or cutaneous malignancy are concerning for alternative causes of facial paralysis requiring workup. The erroneous use of the eponym Bell palsy to refer to all causes of facial paralysis, regardless of the history and presentation, may result in cognitive errors, including premature closure, anchoring bias, and diagnosis momentum. Hence, we recommend replacing the eponym Bell palsy with idiopathic facial nerve paralysis. (c) 2020 Elsevier Inc. All rights reserved.
