Definition   

Otitis is a general term for infection or inflammation of the ear.

Causes, incidence, and risk factors   

Otitis can affect the inner or outer parts of the ear. The condition is classified according to whether it occurs suddenly and for a short time (acute) or repeatedly over a long period of time (chronic).

Specific types of ear infection include:

Symptoms   

Any of the following symptoms may develop with otitis:

Signs and tests   

Your health care provider will examine your ears and use an instrument called an otoscope to look inside them. Signs that may be seen during an exam include a red, painful outer ear or redness or swelling of the eardrum.

Treatment   

Treatment may include antibiotics, depending on the suspected cause of the infection.

Expectations (prognosis)   

Most types of ear infection respond well to treatment. If there is no improvement after 3 days, your doctor may recommend a different antibiotic. In certain uncomplicated cases, a child over 6 months of age who does not have a fever may not be given medicine unless the infection continues after 48-72 hours.
