The tympanic cavity, also known as the middle ear, is a small, air-filled space located between the outer ear and the inner ear. It contains three tiny bones called the ossicles—malleus, incus, and stapes—which help transmit sound vibrations from the eardrum to the inner ear. The tympanic cavity is essential for hearing, as it amplifies sound waves. This cavity is lined with a mucous membrane and connects to the back of the throat through the Eustachian tube. This tube helps equalize pressure in the ear, ensuring proper function and comfort during changes in altitude or pressure.
