Vestibular Neuronitis
Introduction
Vestibular neuronitis causes a self-limited episode of vertigo, presumably due to inflammation of the vestibular division of the 8th cranial nerve; some vestibular dysfunction may persist. Sometimes vestibular neuronitis is used synonymously with viral labyrinthitis. However vestibular neuronitis manifests only with vertigo, whereas in viral labyrinthitis, tinnitus, hearing loss, or both are also present. Although etiology is unclear, a viral cause is suspected. Vestibular neuronitis is usually unilateral.
