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.[1] 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.[2]
