Eustachian valve

The valve of the eustachian tube is an anatomical structure that is located in the posterior wall of the nasopharynx and connects the nasopharynx to the pharynx. It plays an important role in maintaining normal pressure in the eustachian tubes, which connect the middle ear cavity to the pharynx and provide ventilation to the middle ear.

The valve of the Eustachian tube consists of two parts: upper and lower. The upper part is the muscle tissue that is responsible for opening and closing the valve when swallowing. The lower part consists of cartilage tissue and is shaped like a crescent. It fits tightly to the lower wall of the pharynx and prevents air from entering the nasopharynx from the pharynx.

Normal operation of the Eustachian tube valve is necessary to maintain normal pressure in the middle ear and prevent the development of otitis media (inflammation of the middle ear). If the Eustachian tube valve is not functioning properly, dysfunction of the Eustachian tubes may occur, which can lead to impaired ventilation of the middle ear and the development of otitis media.

To maintain normal functioning of the Eustachian tube valve, it is necessary to maintain oral and nasal hygiene. Regular rinsing of the mouth, brushing teeth and nasal cavity, and stopping smoking and alcohol can help keep the Eustachian tube valve functioning properly.
