what are the function of eustachian tube?

This air-containing space is maintained by the Eustachian tube, which opens intermittently to equalize the intratympanic air pressure with the pressure in the external auditory canal. It also removes secretion and epithelial debris from the middle ear by ciliary motion and gravity.

Answer and Explanation: The Eustachian tube in a frog leads from the pharynx to the middle ear. In vertebrates, the middle ear is the chamber between the tympanic membrane...

The Eustachian tube is a small canal that runs between your nose and your middle ear. It helps equalize the pressure in your middle ear. When the Eustachian tube becomes clogged, you feel fullness and pressure in your ear. You might also experience muffled hearing and ear pain.

Obliteration of the Eustachian tube will relieve the patulous Eustachian tubes usually on a permanent basis. A grommet in the eardrum will usually be required permanently to prevent ear blockage, deafness due to fluid build-up in the ear, and other complications.

The tube opens about 1.25 cm behind and slightly below the posterior end of the inferior turbinate. The bony portion is widest at its tympanic end. It passes through the squamous and petrous portions of the temporal bone but narrows gradually to the isthmus, which is the narrowest part of the eustachian tube.

Structure and Function The active opening of the Eustachian tube to relieve positive or negative pressure in the middle ear commonly is called “clearing the ear.” The Eustachian tube is located in the para-pharyngeal space and is closely linked to the infratemporal fossa.

It consists of an air-filled cavity called the tympanic cavity and includes the three ossicles and their attaching ligaments; the auditory tube; and the round and oval windows. The ossicles are three small bones that function together to receive, amplify, and transmit the sound from the eardrum to the inner ear.

The swelling within your ears may prevent your eustachian tubes – structures within your ears which help to regulate the pressure within your ears – from functioning properly. When they're unable to balance the pressure within your ears as needed, it may lead to increased inner-ear pressure, which may cause dizziness.

When the Eustachian tube becomes clogged, you feel fullness and pressure in your ear. You might also experience muffled hearing and ear pain. These ear congestion symptoms can also be caused by problems in your middle ear or the ear canal that affects the eardrum (also called the tympanic membrane).

To restore hearing loss caused by chronic fluid build-up and to prevent delayed speech development caused by hearing loss in children. To place tympanostomy tubes — these tubes help to equalize pressure. It may also help prevent recurring ear infections and the accumulation of fluid behind the ear drum.

Overview. The eustachian tube (pharyngotympanic tube) connects the middle ear cavity with the nasopharynx. It aerates the middle ear system and clears mucus from the middle ear into the nasopharynx. Opening and closing functions of the eustachian tube are physiologically and pathologically important.

It's made of tough cartilage covered by skin. Its main job is to gather sounds and funnel them to the ear canal, which is the pathway that leads to the middle ear. Glands in the skin lining the ear canal make earwax, which protects the canal by cleaning out dirt and helping to prevent infections.

An ear infection occurs when one of your eustachian tubes becomes swollen or blocked, causing fluid to build up in your middle ear. Eustachian tubes are small tubes that run from each ear directly to the back of the throat.

Many people have crackling in the ear when they swallow, and this is normal. This is from the movement and opening of the Eustachian tube (ET). The ET is a complex tube that opens on swallowing to let air into the middle ear from the back of the throat. This is quite normal.

Eustachian tube. A canal that links the middle ear with the back of the nose. The eustachian tube helps to equalize the pressure in the middle ear. Equalized pressure is needed for the proper transfer of sound waves. The eustachian tube is lined with mucous, just like the inside of the nose and throat.

However, once the eustachian tubes are blocked or malfunctioning, it is more difficult for your ears to equalize air pressure and you may experience tinnitus, popping or cracking sounds, mild hearing loss, or problems with balance. For many people, treating eustachian tube dysfunction can alleviate tinnitus.

It's connected to your throat by a pair of narrow tubes called Eustachian tubes. Most ear infections are started by another condition, such as a cold, flu, sinus infection or allergies.
