Eustachian tubes lead to the eardrum. The name for the throat of the from is the gullet.
The function of the eustachian tubes is to drain fluid from the middle ear into the throat and also to equalize the pressure behind the ear drum. Sometimes, the eustachian tubes become inflamed and do not function properly. The most common cause of eustachian tube dysfunction is a viral infection like the common cold. Other causes include throat infections, nasal allergies, and chronic sinus congestion. With eustachian tube dysfunction, fluid may collect in the middle ear because it cannot drain properly. Then, with a yawn or chewing motion, or other maneuver that opens the tube temporarily, the liquid and pressure may suddenly be relieved, leading to the popping sensation.
