Bell's Palsy

Common Name(s)

Bell's Palsy

Bell's palsy is a nonprogressive neurological disorder of one of the facial nerves. This disorder is characterized by the sudden onset of facial paralysis that may be preceded by a slight fever, pain behind the ear on the affected side, a stiff neck, and weakness and/or stiffness on one side of the face. Paralysis results from decreased blood supply (ischemia) and/or compression of the 7th cranial nerve. The exact cause of Bell's palsy is not known. Viral (e.g., herpes zoster virus) and immune disorders are frequently implicated as a cause for this disorder. There may also be an inherited tendency toward developing Bell's palsy. While there is no cure or standard course of treatment for Bell's palsy, eliminating the source of the nerve damage typically results in a good prognosis.

Journal: Otol. Neurotol.. 2014 Mar;35(3):514-8.

 

Bell's palsy is hypothesized to result from virally mediated neural edema. Ischemia occurs as the nerve swells in its bony canal, blocking neural blood supply. Because viral infection is relatively common and Bell's palsy relatively uncommon, it is reasonable to hypothesize that there ...
