title: [Fluctuating vestibular deficit--a new Ménière disease related internal ear disorder].
abstract: A third inner ear disorder similar to Menière's disease and fluctuant hearing loss seems to be due to endolymphatic hydrops. This disorder is characterised by attacks of vertigo without any cochlear symptoms. During the course of the disease, which lasts up to 8 years, the vestibular organ loses its function in most cases. Clinical and electronystagmographic findings are presented, and the possible pathophysiological mechanisms are discussed.
