Ramsay Hunt syndrome is a rare complication of latent VZV infection. [5] As previously stated, Ramsay Hunt syndrome might occur in the absence of cutaneous rash (zoster sine herpete). Interestingly, VZV has been detected by polymerase chain reaction (PCR) in the tear fluid of patients diagnosed with Bell palsy. [6] Ramsay Hunt syndrome is estimated to account for 16% of all causes of unilateral facial palsies in children, and 18% of facial palsies in adults. Ramsay Hunt syndrome is rare in children younger than 6 years. [5]
