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 in adults are outer ear infections (otitis externa), but middle ear infections (otitis media) can occur. Outer ear infections are also called swimmer's ear, because it commonly affects swimmers.
