Patulous Eustachian tube

Uncommon card · No. 168729

Patulous Eustachian tube is the name of a physical disorder where the Eustachian tube, which is normally closed, instead stays intermittently open. When this occurs, the person experiences autophony, the hearing of self-generated sounds. These sounds, such as one's own breathing, voice, and heartbeat, vibrate directly onto the ear drum and can create a "bucket on the head" effect, making it difficult for the patient to attend to environmental sounds. Patulous Eustachian tube is a form of Eustachian tube dysfunction, which is said to be present in about 1 percent of the general population.
