A tube‑like passageway which extends from the middle ear cavity to the back of the throat (nasopharynx). There is one Eustachian tube for each ear. Adenoidal tissue usually surrounds the Eustachian tube openings at the back of the throat. Abnormal Eustachian function is evidenced by negative middle ear pressure.

The Eustachian tube connects the back of your nose with your middle ear. It controls air flow and makes sure the eardrum can vibrate easily. Problems with the Eustachian tube can affect your hearing.

Short canal that connects the middle ear with the back of the throat

tube running from the nasal cavity to the middle ear. The Eustachian tube helps balance air pressure between the outer ear and the middle ear.

air duct from the nasopharynx which enters the anterior wall of the middle ear at its lowest point.

The narrow tube connecting the nose and middle ear to allow air pressure in the middle ear to equalize with the outside environment.

A tube within the middle ear that connects the middle ear cavity to the back of the nose and throat. Its purpose is to adjust the air pressure in the middle ear to match the air pressure on the outside of the eardrum.

part of the middle ear which connects the ear to the nasopharynx.

The eustachian tube is part of the middle ear. It extends from the anterior wall of the tympanic cavity to the nasopharynx. It is lined by ciliated epithelium, varying from simple low columnar to pseudostratified columnar. It's main function is to equalized the air pressure between the tympanic cavity and external environment.

a tube connecting the mouth to the middle ear, allowing air pressure to be equal on both sides of the eardrum.

tube connecting the middle ear to the pharynx.

connects the middle ear space with the throat; maintains equal air pressure on both sides of the tympanic membrane (eardrum).

a short, muco-cartilaginous tube connecting the back of the nose to the middle ear. The anatomy of this tube is such that it tends to close naturally when ambient pressure is higher than middle ear pressure (as on descent in a dive), and tends to open naturally when ambient pressure is lower than middle ear pressure (on ascent).

Tube or canal that connects the middle ear with the nasopharynx and allows for a balance of pressure between the outer and middle ear. Infection can travel via the mucous membranes of the eustachian tube, resulting in middle ear infections.

The middle ear is a sealed, air filled cavity allows the eardrum to move easily. The Eustachian tube connects the back of the nose to the middle ear. Air can pass from the back of the nose to the middle ear through the Eustachian tube to equalize the pressure between the outer and middle ear.

A tube inside the body that links the cavity of the middle ear to the nose and the throat. It is vital for maintaining the correct air pressure so that the eardrum and ossicles can vibrate properly.

a short tube connecting the back of the nose to the middle ear. If clogged, by mucus, equalization is next to impossible.

either of the paired tubes connecting the middle ears to the nasopharynx; equalizes air pressure on the two sides of the eardrum

auditory tube that connects the ears to the nasopharynx. Eustachian tube dysfunction results in poor drainage from the ears to the nasopharynx

a tube that runs from the middle ear to the back of the throat. It allows air pressure on both sides of the ear drum to stay equal.

Normal connection between middle ear and back of throat

A tube in the inner ear that connects with the nose and throat

tube running from the nasal cavity to the middle ear. Helps maintain sinus and middle ear pressure, protecting the ear drum.

Passageway connecting the middle ear to the nose and throat. This opens to equalize pressure in the middle ear.

Hollow structure of bone and cartilage extending from the middle ear to the rear of the throat. By permitting air to leave or enter the middle ear, the tube equalizes air pressure on either side of the eardrum - see equalisation.

The tube that connects the middle ear to the back of the throat; its function is to equalize the air pressure in the ear

a canal that links the middle ear with the throat area. The eustachian tube helps to keep the pressure between the outer ear and the middle ear the same. Having the same pressure allows for the proper transfer of sound waves. The eustachian tube is lined with mucous, just like the inside of the nose and throat.

The tube that runs from the middle ear to the pharynx. The function of the Eustachian tube is to protect, aerate and drain the middle ear (and mastoid). Occlusion of the Eustachian tube leads to the development of middle ear inflammation ( otitis media ). The Eustachian tube is also called the otopharyngeal tube (because it connects the ear to the pharynx) and the auditory tube (and in Latin, the tuba acustica, tuba auditiva, and tuba auditoria). See the entire definition of Eustachian tube

connection between the middle ear and the nasal cavity, which maintains pressure in the ear and may act as a path of infection

A small connection between the throat and the middle ear cavity which in the normal human ear system is utilized to equalize the pressure in the middle ear cavity to the pressure in the atmosphere surrounding the body.

The canal connecting the throat with the middle ear

a passage joining the middle ear and pharynx.

A small tube that connects the middle ear with the back of the throat. It allows the air in the middle ear to be refreshed periodically.

The air duct that connects the nasopharynx (located in the back of the throat and above the hard [bony] palate) with the middle ear; it is usually closed at one end, but opens with yawning and swallowing; it allows ventilation of the middle ear cavity and equalization of pressure on both sides of the eardrum

Small tube running from the middle ear into the throat; provides fresh air to the middle ear and allows fluid to drain from the middle ear.

The air-filled tube connecting the back of the throat with the middle ear. It usually opens during yawning or swallowing, allowing ventilation of the middle ear cavity and equalization of pressure on the two sides of the eardrum

A structure that extends from the throat to the middle-ear cavity and controls air flow between the two.

The tube running from the middle ear into the pharynx that equalizes middle-ear and atmospheric pressure.

A hollow cartilagenous tube connecting the tympanic cavity (middle ear) and the nasopharynx. An open tube can equilibrate the pressure in the middle ear. Yawning opens the tube to allow the ears to "pop!" when changing altitude. image image See also Torus Tubarius

A thin tube between the middle ear and the pharnyx. Its purpose is to equalize pressure on either side of the ear drum.

The Eustachian tube (or auditory tube) is a tube that links the pharynx to the middle ear. In adults the Eustachian tube is approximately 35 mm long. It is named after the 16th century anatomist Eustachius.
