Overview
Otalgia is often due to otitis media which is predominantly an infectious disease of children. Otitis externa is less frequent and is often observed in swimmers.
Epidemiology
Otitis Media:
- Acute Otitis media (AOM) is predominantly a disease of children. After the common cold, it is the second most common reason why children are brought to their family practitioners.
- Male>female
- Peak incidence is between 6-18 months of age.
- About 30% of children younger than 3 years of age visit their primary care physicians with AOM each year, and by their third birthdays 80% to 90% of children have experienced AOM.[1]
Otitis externa:
- Incidence of Otitis externa is 400 out of 100000 persons in USA.
- Higher incidence in summer.
- No sex predilection.
- Frequently seen in people who are associated with aquatic activities.
- No association with age but a slight increase in prevalence is noted in patients aged more than 65 yrs was postulated to occur secondary to an increase in comorbidities, as well as an increase in the use of hearing aids, which may cause trauma to the external auditory canal.
Cholesteatoma
- Incidence is unknown.
Mastoiditis
- Incidence is 4 per 100000 persons in the USA.
- Common in children.
- Median age is 12-24 months.
