Overview
Incidence
- The incidence of acute otitis externa is usually high:
- The incidence of acute otitis externa is greater in climates that experience more year-round humidity, increased by a more conducive climate to bacterial and fungal colonization.[3][4]
Prevalence
- A study of acute otitis externa patients in the United Kingdom revealed that the disease prevailed for 12-months in approximately 24 per 100,000 individuals.[5][6]
Case Fatality Rate
- The annual Case Fatality Rate for malignant necrotizing otitis externa is approximately 10-20%.[7]
Age
- The majority of acute otitis externa cases occur in adults between 65 and 74 years old.[6]
- Due to increased humidity, there is an increase in acute otitis externa among children between 5 and 14 years old.[8]
- The majority of malignant otitis externa patients
