Causes in Alphabetical Order

Infectious Causes

Herpes simplex virus reactivation is the most likely cause of Bell's Palsy.
Herpes Zoster may be the second most common viral infection.
Cytomegalovirus
Epstein Barr virus
Adenovirus
Rubella virus
Mumps
Influenza B

-===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.
