H81: Disorders of vestibular function

H81.0: Ménière disease

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 actual hearing organ, the cochlea, is in the inner ear. The cochlea consists of a channel of bone in a spiral, like a snail. Inside the cochlea are the sensory cells for hearing. The inner ear connects to the brain via the auditory nerve.

Your inner ear is repeatedly failing to work properly. You then feel dizzy and your hearing is poor. You may also have ringing in your ears. The symptoms usually last for a few minutes or a few hours. Over time the symptoms may get worse. After a few years you may be able to hear nothing at all on the side affected.

The cause of this disorder is not yet known.
