Diagnostic Testing For Endolymphatic Hydrops
Otolaryngologic Clinics of North America, 1997The development of a sensitive and specific diagnostic test for endolymphatic hydrops has eluded investigators for over 30 years. The absence of such a test has hampered basic and clinical research into Meniere's disease and related entities. Presently used tests are limited in their applicability because of their low sensitivity and specificity and a ...

Contralesional subjective visual horizontal predicts endolymphatic hydrops
Acta Oto-Laryngologica, 2020Background: The subjective visual horizontal (SVH) is a test of utricular function that assesses conjugate ocular torsion which is a component of the ocular tilt reaction (OTR).

Electrocochleography in Experimental Endolymphatic Hydrops
Acta Oto-Laryngologica, 1994This study investigated whether dominant negative summating potential (DNSP) is absent at all stages of induced hydrops development, including the early stages of hydrops formations. Electrocochleography (ECoG) was done 3 days to 20 weeks after obliteration of the endolymphatic sac in guinea pigs, by electrodes attached to the cochlear bony wall on the

Effects of endolymphatic hydrops on acoustic energy absorbance
Acta Oto-Laryngologica, 2020Background: The presence of endolymphatic hydrops (EH) may cause hearing loss and affect the transmission of acoustic energy to the inner ear. Objectives: Acoustic energy absorbance on wideband acoustic immittance (WAI) was evaluated, focusing especially

Otology and Neurotology, 2020
Background: For clinical confirmation of the diagnosis of hydropic ear disease (HED) (Menière) by MR imaging, two routes of contrast enhancement of the perilymphatic space are currently being used: intratympanic and intravenous.

A Case Of Delayed Endolymphatic Hydrops
Auris Nasus Larynx, 1992A 30-year-old male with delayed endolymphatic hydrops was given a sac operation. An intradural portion of the endolymphatic sac was resected and the epithelial surface was examined under a scanning electron microscope. The epithelium showed fibrous degeneration and disappearance of the epithelial cells. Pathogenesis of degeneration of the endolymphatic

Background Furosemide-loading cervical vestibular-evoked myogenic potential (FVEMP), in which vestibular function is improved via diuretics-induced dehydration, can be used to estimate the presence of endolymphatic hydrops, one characteristic of Menière ...

Effect of acute endolymphatic hydrops overload on the endolymphatic sac
Acta Oto-Laryngologica, 2008Homeostasis of endolymph volume is a complex mechanism, in which the endolymphatic sac (ES) may play an important role.To elucidate the effect of acute endolymphatic hydrops (EH) on the ES and to gain further information about the volume and pressure regulative function of the ES.Distilled water was injected into the middle ear cavity of adult CBA/J ...

Endolymphatic space imaging in patients with delayed endolymphatic hydrops
Acta Oto-Laryngologica, 2009Magnetic resonance imaging (MRI) after intratympanic gadolinium injection can reveal endolymphatic hydrops (ELH) in patients with delayed ELH (DELH). Patients with contralateral DELH may have bilateral ELH.DELH has previously been diagnosed based on clinical history, hearing and vestibular examinations. DELH is classified into three types: ipsilateral,

Endolymphatic Hydrops—Fiftieth Anniversary
Acta Oto-Laryngologica, 1989The histopathological picture in Meniere's disease was described for the first time in 1938, in two independent reports. One was by Hallpike & Cairns in Great Britain, and the other by Yamakawa in Japan. Selections of illustrations from these two reports have been compiled and compared.(ABSTRACT TRUNCATED AT 250 WORDS)
