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.
An ear infection is caused by a bacterium or virus in the middle ear. This infection often results from another illness â cold, flu or allergy â that causes congestion and swelling of the nasal passages, throat and eustachian tubes.
