==Differentiating Bell's palsy from other Diseases==
 
===Lyme Disease===
 
:*Facial nerve palsy is the most common cranial neuropathy associated with Lyme meningitis.
:*Screening for antibodies to B.burgdorferi not recommended among patients with seventh nerve palsy with no additional manifestations of Lyme disease.
:*Findings suggestive of possible Lyme disease include the development of facial palsy in a young patient, heart block, arthritis, vertigo, and hearing loss.
 
===HIV===
 
:*[[HIV]] infection rarely causes facial palsy.
:*Onset at the time of sero-conversion when a [[CSF]] lymphocytosis is usually present.
:*In the later stages when cellular immunity wanes, the facial palsy is typically due to another infection such as Zoster, chronic demyelinating polyradiculopathy, or meningeal lymphomatosis.
 
===Melkersson-Rosenthal Syndrome===
 
:*Facial paralysis, episodic facial swelling, and a fissured tongue, typically beginning in adolescence, with recurrent episodes of facial palsy.
:*Incomplete forms of this syndrome outnumber those with the classic triad.
:*The cause is unknown, and treatment unproven.
 
===Other Entities===
 
:*Bacterial infection of the middle ear (otitis media)
:*[[Cholesteatoma]], or tumors should be suspected if the onset of facial palsy is gradual.
:*[[Sarcoidosis]], especially in patients with bilateral facial palsy.
:*Sjogren's syndrome is an unusual cause.
