What is torus tubarius?

The torus tubarius, also known as the cushion of the pharyngeal ostium of the Eustachian tube, is a small tubular structure located in the pharyngeal wall near the opening of the Eustachian tube. It is made up of fibrous tissue and muscle and is covered with mucous membrane.

The main function of the torus tubarius is to help regulate the pressure in the middle ear by allowing air to pass between the middle ear and the nasopharynx. It also helps to protect the Eustachian tube from collapse and maintain its shape.

The torus tubarius can become inflamed or swollen due to infections or allergies, which can lead to blockage of the Eustachian tube and symptoms such as ear pain, hearing loss, and a feeling of fullness in the ear. Treatment for inflammation of the torus tubarius may include medications to reduce swelling and inflammation, as well as measures to alleviate symptoms such as pain and congestion.

Overall, the torus tubarius plays an important role in maintaining ear health and proper function of the middle ear.
