Labyrinthitis Overview
Labyrinthitis means an inflammation of the inner ear structure called the labyrinth. Sometimes the term labyrinthitis refers to other causes of inner ear problems that have no inflammation because those problems produce similar symptoms.
- You have a labyrinth in each of your inner ears,
encased in thick bone near the base of your skull. As the name implies, the
labyrinth is a maze of interconnected fluid-filled channels and canals. Half
of the labyrinth, the cochlea, is shaped like a snail's shell. It sends
information about sounds to the brain. The other half looks something like a
gyroscope with 3 semicircular canals connected to an open cavern or vestibule. The vestibule portion of the labyrinth sends information to the brain regarding the position and movement of your head. Any disturbance of the vestibule can lead to faulty information going to your brain.
- Your eyes also send positioning information to your brain. When information from the labyrinth and the eyes don't match, the brain has trouble interpreting what is happening. This misinterpreting often leads to a sensation that you are spinning (vertigo) or a feeling that you are moving when in fact you are remaining still. Feelings of motion sickness (nausea and vomiting) often follow. Sometimes you will experience hearing loss or abnormal sounds such as a high- or low-pitched ringing (tinnitus).

Benign Positional Vertigo Overview
Benign positional vertigo (BPV)-or simply vertigo-is a disorder of the inner ear. You feel a sudden sensation of movement or spinning when you move your head or hold it in a certain position.
The inner ear is located within your skull and consists of the cochlea, a chamber shaped like a snail shell, where sound is transformed to nerve signals for the brain, and 3 semi-circular canals that function like a gyroscope, relaying information about head position and movement to the brain.
The semicircular canals contain fluid and special sensors that, when disturbed, inform the brain of a change in head position. It is thought that when you have BPV small particles become dislodged within the inner ear and then bounce around when your head moves, triggering faulty signals that your head is still moving even after it stops. This sensation of movement or imbalance when you are not moving is called vertigo, the primary sympto...
