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.
Ear infections occur when one of your Eustachian tubes becomes swollen or blocked and fluid builds up in your middle ear. Eustachian tubes are small tubes that run from each ear directly to the back of the throat. The causes of Eustachian tube blockage include: 1  allergies. 2  colds. 3  sinus infections.
