Causes And Risk Factors For An Ear Infection

Smaller Eustachian Tubes

Smaller Eustachian tubes can increase an individual's risk of developing an ear infection. This is particularly true for children, who are already at an increased risk of ear infections anyway. The Eustachian tubes are parts of the body that begin at the back of the nose and run to each of the middle ears (one on each side). This tubing is necessary for connecting the middle ears to the back of the nose. The first portion of the tube is made from cartilage, while the part closest to the ear is made out of bone. Eustachian tubes can become clogged with mucus and other substances when individuals have an infection or cold. For those who have smaller Eustachian tubes than average, these kinds of blockages may be more frequent. If a Eustachian tube is partially or totally blocked, individuals might feel like their ear is full of fluid, and they might feel popping or clicking in the ear.
