Nerve conduction time in Bell's palsy.

This paper deals with the problem of idiopathic Bell's palsy. One hundred thirty seven cases of Bell's palsy were analyzed. It is shown that the use of E.M.G., facial nerve conduction time, and stimulating thresholds necessary to achieve supramaximal stimulation reduced the number of patients with complete paralysis in the poor prognosis group to 20.6% as compared to 37.5% when the nerve excitability test alone was utilized.
