A case report of facial nerve palsy associated with chickenpox.

We examined a very unusual patient who developed peripheral facial palsy with chickenpox. A survey of the English literature revealed that eight such patients had been reported, but the period between the appearance of the vesicles of varicella and the facial nerve palsy ranged from five days before to 16 days after the eruption development. We presume that the route of infection was neurogenous in patients who had palsy after the appearance of the eruptions, but haematogenous in patients who had palsy before the appearance of vesicles. The two patients whose infection route was presumed to be haematogenous, had a poor prognosis.
