Electronystagmographic findings in idiopathic facial paralysis have been adduced by some as evidence for a vascular etiology; others, on clinical grounds, hold that it is a viral disease. Electronystagmographic abnormalities appeared in 43 percent of 28 patients with idiopathic, and 42 percent of 19, with herpes zoster facial paralysis. The only observed difference between the two types of facial paralysis was evidence for more widespread neural involvement and a greatly heightened percentage (56 percent versus 8 percent) of denervation, in the herpes zoster group. The clinical findings indicate that idiopathic facial paralysis is a polyneuropathy involving the Vth and VIIIth cranial nerves. Its protean manifestations and clinical similarity to a disease known to be viral in origin, appear to support the hypothesis that it is also a viral disorder.
