Epidemiology
The incidence of Ramsay Hunt syndrome is approximately 5 per 100,000 people per year.[3] This is in comparison to Bell’s palsy, which has an incidence around 3 to 6 times greater at 15 to 30 per 100,000 people per year.[4] It is estimated that 3% to 18% of cases of peripheral facial paralysis are caused by Ramsay Hunt syndrome.[2]
The syndrome can affect people of any age, but it is more common in people ages >50 years, and it is extremely rare in children.[5][6]
