Labyrinthitis

Labyrinthitis, also known as vestibular neuritis, is the inflammation of the inner ear. It results in a sensation of the world spinning and also possible hearing loss or ringing in the ears. It can occur as a single attack, a series of attacks, or a persistent condition that diminishes over three to six weeks. It may be associated with nausea, vomiting, and eye nystagmus.

It can occur as a single attack, a series of attacks, or a persistent condition that diminishes over three to six weeks. It may be associated with nausea, vomiting, and eye nystagmus. The cause is often not clear. It may be due to a virus, but it can also arise from bacterial infection, head injury, extreme stress, an allergy, or as a reaction to medication. 30% of affected people had a common cold prior to developing the disease. Either bacterial or viral labyrinthitis can cause a permanent hearing loss in rare cases. This appears to result from an imbalance of neuronal input between the left and right inner ears. Vestibular neuritis affects approximately 35 million people per year. It typically occurs in those between 30 and 60 years of age. There is no significant gender difference. It derives its name from the labyrinths that house the vestibular system, which senses changes in head position. The main symptom of labyrinthitis is severe vertigo. Rapid and undesired eye motion (nystagmus) often results from the improper indication of rotational motion. Nausea, anxiety, and a general ill feeling are common due to the distorted balance signals that the brain receives from the inner ear.
