Abstract

There is controversy on the management of the idiopathic facial nerve palsies (Bell’s palsy). About two out of every three patients have a nerve conduction block alone and recover completely in less than one month.¹ The rest develop denervation of the facial muscles to a varying degree and never recover completely. In addition, contracture of the facial muscles may occur, with severe disfigurement. About 10% of all patients with facial palsy have complete denervation and serious sequelae.² Using electromyography³ and measurement of the anodal galvanic threshold⁴ an accurate prognosis can be given within the first week.
