“…Tympanic membrane, tympanic cavity, and auditory ossicular chain Transient conductive hearing loss: Researchers conducting experiments on themselves have shown that closure of the Eustachian tube reduces the pressure in the tympanic cavity to 165 mmWs (daPa) within two hours (11) and thereby lessens the vibration of the tympanic membrane, mainly in the lower frequencies (e1). If the Eustachian tube is blocked for months, a mucoserous tympanic effusion arises, leading to conductive losses of up to 40 dB over the entire frequency range.…”

The available epidemiological data on hearing loss in Germany are inadequate. It is roughly estimated that 13 to 14 million people in Germany are in need of treatment for hearing loss. The most common types of permanent hearing loss are those associated with old age, chronic otitis media, and acoustic trauma. Transient hearing loss is particularly common in childhood as a result of inadequate ventilation of the middle ear. The further technical development of cochlear implants has now widened their indications to include severe congenital deafness and presbycusis.

“…Eustachian tube dysfunction affects the normal flow of gas by reducing its ability to help regulate middle ear pressure, even though Eustachian tube involvement in the mechanisms of middle ear gas regulation remains controversial. 20,21 Some investigators 20 argue that the Eustachian tube supplies gases to the middle ear and that its loss of function results in a reduction in pressure, while others 21 propose the opposite, maintaining that gases are produced by the mucosa of the middle ear and mastoid and that the Eustachian tube functions only in gas evacuation.…”
