It is possible that the main title of the report Patulous Eustachian Tube is not the name you expected. Please check the synonyms listing to find the alternate name(s) and disorder subdivision(s) covered by this report.
In patulous eustachian tube (pET) dysfunction, the eustachian tube stays open most of the time. The eustachian tube is a passageway from the back of the nose to the middle ear that may be opened or closed by action of a valve-like device. Under normal circumstances, it remains closed for most of the day, opening only on occasion to equalize air pressure in the middle ear and the exterior environment.
If the tube remains open, the patient complains of hearing one's own voice or one's breathing as too loud (autophony), hearing echoes of one's own voice, or hearing ocean waves much like the sound produced by holding a shell over one's ear.
The condition is benign but may generate, over time, serious and even extreme responses to the abnormal sounds.
