  2. Vocal cords - Wikipedia

    en.wikipedia.org/wiki/Vocal_cords

    To oscillate, the vocal folds are brought near enough together such that air pressure builds up beneath the larynx. The folds are pushed apart by this increased subglottal pressure, with the inferior part of each fold leading the superior part. Such a wave-like motion causes a transfer of energy from the airflow to the fold tissues. [28]

  3. Endolymphatic hydrops - Wikipedia

    en.wikipedia.org/wiki/Endolymphatic_hydrops

    The symptoms of endolymphatic hydrops include the feeling of pressure or fullness in the ears, hearing loss, tinnitus (ringing in the ears) and balance problems. Individuals who have Ménière's disease have a degree of endolymphatic hydrops that is strong enough to trigger the symptoms of this disease, but individuals with endolymphatic ...

  4. Myringotomy - Wikipedia

    en.wikipedia.org/wiki/Myringotomy

    A myringotomy is a surgical procedure in which an incision is created in the eardrum (tympanic membrane) to relieve pressure caused by excessive buildup of fluid, or to drain pus from the middle ear. A tympanostomy tube may be inserted through the eardrum to keep the middle ear aerated for a prolonged time and to prevent reaccumulation of fluid ...

  5. Ear pain - Wikipedia

    en.wikipedia.org/wiki/Ear_pain

    As atmospheric pressure increases with descent, the eustachian tube collapses due to pressure within the middle ear being less than the external pressure, which causes pain. In severe cases, middle ear hemorrhage or tympanic membrane rupture can result. [16] Tympanic membrane rupture: disruption of the eardrum. This can be caused by a blow to ...

  6. Inner ear - Wikipedia

    en.wikipedia.org/wiki/Inner_ear

    When the stapes presses on the oval window, it causes the perilymph, the liquid of the inner ear to move. The middle ear thus serves to convert the energy from sound pressure waves to a force upon the perilymph of the inner ear. The oval window has only approximately 1/18 the area of the tympanic membrane and thus produces a higher pressure ...

    When wax builds up, it causes muffled hearing, tinnitus, or aural fullness (plugged-up feeling in the ears). What to do You can do a few different things at home to help relieve earwax buildup.

  8. Middle ear barotrauma - Wikipedia

    en.wikipedia.org/wiki/Middle_ear_barotrauma

    Pressure on the outer side of the eardrum normally closely follows ambient pressure, and in the inner ear pressure equalises through the Eustachian tube, which must be open for gas to flow through. If the diver does not equalise sufficiently a pressure difference may develop that is large enough to damage the eardrum as described.

  9. Tragal pressure - Wikipedia

    en.wikipedia.org/wiki/Tragal_pressure

    Tragal pressure is pressure that is applied to the cartilage at the front, or anterior aspect of the ear canal (called the tragus), closing the canal and increasing pressure on the tympanic membrane (ear drum). [1] Tragal pumping is the act of repeatedly applying tragal pressure in quick succession to help deliver ear drops deeper into the ear ...
