About Bell’s Palsy
Bell’s palsy is a sudden, temporary dysfunction of the facial nerve, resulting in weakness of the muscles on the affected side of the face. Patients may experience drooping of the face with difficulty closing the eye. While the cause of Bell’s palsy is not known, treatment for most patients is with oral corticosteroids for 1 week and prevention of complications to the eye from corneal exposure and ulceration. The vast majority of patients recover within 1-3 months with little residual deficits. If the clinical features atypical or if the facial weakness is recurrent, further investigations are required to diagnose rarer causes for facial nerve palsy.
