title: Diagnosis and management of Bell's palsy.
abstract: Bell's palsy (BP) is an idiopathic peripheral facial nerve paralysis of sudden onset. Its most alarming symptom is unilateral facial weakness, which can result in the inability to close the eyelids, smile, or whistle. The pathogenesis of BP is controversial and is believed to be caused by inflammation of the facial nerve at the geniculate ganglion. Many viruses, especially herpes simplex and herpes zoster, have been suggested as initiators of this inflammatory process; however, this has not been proven. This report describes the case of a 14-year-old girl with right hemifacial palsy who sought treatment one month after the onset of palsy. The patient experienced a satisfactory recovery within 30 days of treatment and has maintained a stable physical outcome after 15 months of follow-up. Early treatment based on careful investigation of BP, with particular attention given to the differential diagnosis of BP, can improve the patient's function and esthetics.
