How do altitude changes or air travel affect Eustachian tube problems?
A rapid change in altitude and thus air pressure is equalized across the eardrum by a normally functioning Eustachian tube. A healthy tube opens frequently and widely enough to equalize these changes in air pressure. With altitude changes during the descent of an airplane, air pressure increases as the plane lowers. The air pressure change pushes the eardrum inward (retraction). Persons with Eustachian tube blockage can develop fullness of the ear, dulled hearing, and possibly pain when this occurs. Those with poorly functioning Eustachian tubes may experience similar symptoms when riding elevators, driving through the mountains, or diving to the bottom of a swimming pool. Scuba divers learn tricks to equalize their ear pressures. How is Eustachian tube blockage treated? Several maneuvers may be done to improve Eustachian tube function and thus aid in equalization of air pressure. • The simple act of swallowing activates the muscles in the back of the throat that help open the Eustachi
