Labyrinthitis is usually caused by a virus and sometimes by bacteria. Having a cold or flu can trigger the condition. Less often, an ear infection may lead to labyrinthitis. Other causes include allergies or certain drugs that are bad for the inner ear.
Your inner ear is important for both hearing and balance. When you have labyrinthitis, the parts of your inner ear become irritated and swollen. This can make you lose your balance and cause hearing loss.
