trummiõõnsust

Trummiõõnsust refers to the tympanic cavity, the air-filled space within the temporal bone of the skull that houses the ossicles of the middle ear. This cavity is connected to the nasopharynx by the Eustachian tube, which equalizes air pressure on both sides of the eardrum. The tympanic cavity is lined with a mucous membrane and contains three small bones: the malleus, incus, and stapes. These ossicles transmit sound vibrations from the eardrum to the oval window, the entrance to the inner ear. Inflammation or infection of the tympanic cavity is known as otitis media, a common condition, especially in children. The proper functioning of the tympanic cavity is crucial for hearing, as it plays a vital role in the mechanical transmission of sound waves. Its anatomical location and connections are essential for maintaining auditory health and function.
