![]() These causes can often be treated with decongestant medication or antibiotics, but in severe cases, surgery may be necessary. As external auditory meatus is āSā shaped, therefore, during examination of ear, the auricle is pulled upwards, backwards, outwards in adults, to straighten the ear canal to a certain extent and provide a better view in examination. Conditions such as nasal congestion, infection of the ear or sinus, or allergies may cause these symptoms and lead to eustachian tube problems. During examination of ear, the auricle is pulled upwards, backwards, outwards. When functioning normally, it is a closed tube that opens when we swallow, yawn or. Visual examination of the eardrum with a lighted scope helps to determine if the cause is inflammation, swelling, or fluid in the ear. The eustachian tube is the structure that links the nose and the middle ear. Ear tubes are made from various materials and consist of small, cylindrical tubes that are positioned through the eardrum. When the eustachian tube will not open enough to equalize pressure, symptoms such as discomfort, dizziness, or ringing in the ear may result. The tubes can alleviate hearing loss caused by the accumulation of fluid in the middle ear. When atmospheric pressure changes rapidly, causing a sudden feeling of blockage in the ear (such as during airplane travel), these activities can be done on purpose to open the tube and equalize the pressure within the middle ear. Overview The Eustachian tube is an opening that connects the middle ear with the nasal-sinus cavity. If the Eustachian tube cannot open, a person may suffer hearing impairment, ear pain, a sensation of fullness in one or both ears, tinnitus, and other symptoms. Conducts air between middle ear to throat. ![]() Contains fluid which transmits vibration to the spiral organ. This is the tube that connects the outer ear to the inside or middle ear. Provides air-filled space for auditory ossicles to function B. Most of the time the eustachian tube is closed, opening only during activities such as yawning, swallowing, and chewing, to allow air through the passage between the middle ear and nasopharynx. What is the function of the auditory tube A.
