Labyrinthitis is inflammation of the labyrinth, a maze of fluid-filled channels in the inner ear. Vestibular neuritis is inflammation of the vestibular nerve (the nerve in the ear that sends messages related to motion and position to the brain). [2] [3] [4] Both conditions involve inflammation of the inner ear. [5]
A labyrinthine fistula is an abnormal opening in the inner ear.This can result in leakage of the perilymph into the middle ear. [1] This includes specifically a perilymph fistula (PLF), an abnormal connection between the fluid of the inner ear and the air-filled middle ear.
Interference with or infection of the labyrinth can result in a syndrome of ailments called labyrinthitis. The symptoms of labyrinthitis include temporary nausea, disorientation, vertigo, and dizziness. Labyrinthitis can be caused by viral infections, bacterial infections, or physical blockage of the inner ear. [8] [9]
BPPV is a type of balance disorder along with labyrinthitis and Ménière's disease. [3] It can result from a head injury or simply occur among those who are older. [3] Often, a specific cause is not identified. [3] When found, the underlying mechanism typically involves a small calcified otolith moving around loose in the inner ear. [3]
The most common vestibular diseases in humans are vestibular neuritis, a related condition called labyrinthitis, Ménière's disease, and BPPV. In addition, the vestibular system's function can be affected by tumours on the vestibulocochlear nerve , an infarct in the brain stem or in cortical regions related to the processing of vestibular ...
Otitis interna, or labyrinthitis, involves the inner ear. The inner ear includes sensory organs for balance and hearing. When the inner ear is inflamed, vertigo is a common symptom. Other symptoms in adults include pain and drainage from ear or problems with hearing. [8]
Known causes include genetics, maternal illness and injury. Examples of these causes are physical trauma, acoustic neuroma, maternal prenatal illness such as measles, labyrinthitis, microtia, meningitis, Ménière's disease, Waardenburg syndrome, mumps (epidemic parotitis),mastoiditis or due to an overstrained nervus vestibulocochlearis after a brain surgery to close to the nerve.
Vertigo is a condition in which a person has the sensation that they are moving, or that objects around them are moving, when they are not. [1] Often it feels like a spinning or swaying movement.
