Ear infection - chronic

Middle ear infection - chronic; Otitis media - chronic; Chronic otitis media; Chronic ear infection

Chronic ear infection is fluid, swelling, or an infection behind the eardrum that does not go away or keeps coming back. It causes long-term or permanent damage to the ear. It most often involves a hole in the eardrum that does not heal.

Ear anatomy

The ear consists of external, middle, and inner structures. The eardrum and the 3 tiny bones conduct sound from the eardrum to the cochlea.

Middle ear infection (otitis media)

Otitis media is an inflammation or infection of the middle ear. Acute otitis media (acute ear infection) occurs when there is bacterial or viral infection of the fluid of the middle ear, which causes production of fluid or pus. Chronic otitis media occurs when the eustachian tube becomes blocked repeatedly due to allergies, multiple infections, ear trauma, or swelling of the adenoids.

Middle ear infection

A middle ear infection is also known as otitis media. It is one of the most common of childhood infections. With this illness, the middle ear becomes red, swollen, and inflamed because of bacteria trapped in the eustachian tube.

Eustachian tube

Ear infections are more common in children because their eustachian tubes are shorter, narrower, and more horizontal than in adults, making the movement of air and fluid difficult. Bacteria can become trapped when the tissue of the eustachian tube becomes swollen from colds or allergies. Bacteria trapped in the eustachian tube may produce an ear infection that pushes on the eardrum causing it to become red, swollen, and sore.
