Labyrinthitis

Labyrinthitis is an ailment of the inner ear and a form of unilateral vestibular dysfunction. It derives its name from the labyrinths that house the vestibular system, which senses changes in head position. Labyrinthitis can cause balance disorders, vertigo, hearing loss and tinnitus.

Labyrinthitis is usually caused by a virus, but it can also arise from bacterial infection, head injury, extreme stress, an allergy or as a reaction to medication. Both bacterial and viral labyrinthitis can cause permanent hearing loss.

Labyrinthitis often follows an upper respiratory tract infection (URI).
