H74: Other disorders of middle ear and mastoid
H74.4: Polyp of middle ear
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.
The inside of the middle ear is lined with mucous membrane. The mucous membrane is made up of many individual building blocks. These building blocks are called cells. If certain cells multiply, the mucous membrane in the middle ear can bulge out.
Your middle ear mucous membrane disorder may be caused by the fact that you have repeatedly had inflammation in your middle ear.
When someone has a middle ear mucous membrane disorder, their hearing is usually worse than usual. They may also constantly hear a high-pitched sound. This is also known as tinnitus. Fluid may also be discharged from the ear.
