Home > Health Library > Middle Ear
Most ear infections form in the middle ear. The eustachian tube carries fluid from the middle ear to the throat. Sometimes during a cold, the eustachian tube becomes swollen and fluid is trapped in the middle ear. Bacteria or viruses can grow in this fluid and form an ear infection.
