H65.3: Chronic mucoid otitis media

The ear is a sensory organ that is used to hear and to maintain one’s balance. There are 3 different areas in the ear: the outer ear, middle ear and inner ear. The middle ear begins behind the eardrum. It consists of the air-filled tympanic cavity and the 3 ossicles. The ossicles transmit sounds from the eardrum to the inner ear in the form of vibrations.

If your middle ear is inflamed for a long time, your hearing gets worse. Fluid may be repeatedly discharged from the ear. The fluid may be clear, slimy or purulent. The ear may be painful.
