Auditory Tube (Eustachian): Connection between the Middle Ear and the Pharyngeal Cavity

The auditory tube, also known as the Eustachian tube, is an important structure connecting the middle ear with the pharyngeal cavity. This thin tube plays an important role in maintaining the normal function of the auditory system by ensuring that the air pressure inside the tympanic cavity is equalized with respect to the external environment.

The Auditory Trumpet is named after the Italian anatomist Bartolomeo Eustache, who first described it in the 16th century. It is a narrow and flexible structure, about 3-4 centimeters long. The tube is located behind the eardrum and connects the middle ear to the back of the nasopharynx.

One of the main functions of the Auditory Tube is to equalize the air pressure inside the tympanic cavity with atmospheric pressure. When external pressure changes, such as when climbing to great heights or going underwater, the Eustachian Tube opens, allowing air to flow freely between the middle ear and the pharyngeal cavity. This allows pressure balance on both sides of the eardrum to be maintained, which in turn helps prevent discomfort or damage to the hearing aid.

In addition, the Auditory Tube also plays an important role in the drainage and ventilation of the middle ear. It helps remove excess secretions and air from the middle ear, keeping it healthy. When we swallow or yawn, we activate the muscles that open the Eustachian Tube, allowing air to circulate in and out of the middle ear.

However, sometimes the Eustachian Tube can become clogged or dysfunctional, which can lead to hearing problems and a feeling of fullness in the ears. Some of the most common reasons that can cause Eustachian Tube dysfunction include a runny nose, allergic reactions, upper respiratory tract infections, and changes in air pressure. In such cases, treatment may be required to eliminate the causes and restore normal function of the Auditory Tube.

In conclusion, the Auditory Tube (Eustachian tube) plays an important role in maintaining the normal function of the auditory system. It ensures equalization of air pressure inside the tympanic cavity and the pharyngeal cavity, and also provides drainage and ventilation of the middle ear. Disorders of the function of the Auditory Tube can lead to discomfort, hearing problems and a feeling of fullness in the ears. If you have such problems, it is recommended to consult a doctor for diagnosis and treatment. Understanding the role and function of the Auditory Tube will help us take better care of our hearing health and prevent possible complications.



The middle ear tube is the tube (tube) connecting the tympanic cavity (middle ear cavity) to the mouth (pharynx).

Function of the Eustachian tube: - to ensure barofunction of the hearing organ; - to protect against damage by foreign bodies and irritants, especially when the body is in an upright position; - serves to prevent the spread of infection. Through the Eustachian tube, air from the pharynx enters the tympanic cavity. Due to the negative pressure created in the pharynx by the stream of exhaled air, the air passes through the auditory tube under a pressure of about 8-12 cm and accumulates in the middle ear. It also gets there from the atmosphere through the external auditory canal, which is used as a valve: with a strong wave of hearing
