Recent evidence suggests that viral infection is the most likely underlying cause of Bell's palsy. Rapidity of onset is a due to the diagnosis; unilateral facial weakness or paralysis develops over 24 to 48 hours. Rule out other causes of peripheral facial paralysis, such as Ramsay Hunt syndrome and Lyme disease. Although most cases of Bell's palsy resolve without medical or surgical intervention, older patients and those with abnormal electroneurographic results are less likely to have complete recovery of facial function. Early treatment with an oral corticosteroid is likely to enhance recovery; concurrent use of acydovir may also be helpful. Surgical decompression has been effective in patients with abnormal electroneurographic results.
