Ramsay Hunt syndrome in children.

In a retrospective study, 52 children were diagnosed with Ramsay Hunt syndrome. The facial palsy was milder and complete recovery of the function was achieved in 78.6% of patients. Associated cranial neuropathies were less common in children than in adults. The timing of vesicle appearance tended to be delayed in children. In preschool children, Ramsay Hunt syndrome was rare, although the frequency has recently increased. The syndrome is relatively common in older children. This study suggested that vaccination can prevent or reduce the occurrence of Ramsay Hunt syndrome.
