In the inner ear, the labyrinth holds the organs of balance and hearing. It's made up of two parts:
- Bony labyrinth
- Membranous labyrinth
The membranous labyrinth is encased in bone and contains a fluid called endolymph.
When the head moves, the fluid also moves. This causes nerve receptors in the membranous labyrinth to signal the brain about the body's motion.
Too much fluid buildup in the labyrinth can interfere with the normal balance and hearing signals between the inner ear and the brain. This is Ménière's disease.
Fluid buildup in this area may be caused by:
- Allergies.
- Abnormal immune system response.
- Abnormal fluid drainage caused by a blockage.
- Head injury.
- Genetics.
- Migraine headaches.
- Viral infection.
Most often, Ménière's disease is caused by more than one factor.
