Middle Ear Infections in Adults. While eustachian tube dysfunction is more common in children, poor tubal function can persist into adulthood and is the main cause for middle ear infections in adults. When fluid or bacteria become trapped inside the ear from the eustachian tube not functioning normally, an infection can occur.
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.
