Definition of Labyrinthitis:

Labyrinthitis is an ear disorder that involves irritation and swelling of the inner ear.

Causes, incidence, and risk factors:

The cause of labyrinthitis is unknown. However, it commonly occurs after otitis media (ear infection) or an upper respiratory infection, so it is thought to be related to infection with a virus or bacteria. It may also follow allergy, cholesteatoma, or after taking certain drugs that are dangerous to the inner ear.

During labyrinthitis, the parts of the inner ear become irritated and inflamed. This interferes with their function, which includes the ability to keep your balance.

The following raise your risk for labyrinthitis:

• Recent viral illness, respiratory infection, or ear infection
• Use of certain prescription or nonprescription drugs (especially aspirin)
• Stress
• Fatigue
• History of allergies
• Smoking
• Drinking large amounts of alcohol
