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)

Animal models of endolymphatic hydrops
American Journal of Otolaryngology, 1982Endolymphatic hydrops in the animal can be produced by various methods. The most promising is obliteration of the endolymphatic duct in the guinea pig. The extent of hydrops is similar to that of Ménière's disease specimens, but the animals are asymptomatic.

Hypoplasia of the Vestibular Aqueduct and Endolymphatic SAC in Endolymphatic Hydrops
Otolaryngology–Head and Neck Surgery, 1978Four temporal bones from three previously reported cases showing endolymphatic hydrops and pathology of the vestibular aqueduct (VA) and endolymphatic sac (ES) were investigated further.Pathology of the VA and ES was studied by measuring the sizes of the VA and ES, paying particular attention to the proximal rugose portions.

Cochlear Blood Flow in Endolymphatic Hydrops
Acta Oto-Laryngologica, 1988There is no animal model for Meniere's disease but by obliteration of the endolymphatic duct, endolymphatic hydrops may be achieved in several animal species. In order to measure the cochlear blood flow in ears with endolymphatic hydrops the endolymphatic duct was obliterated in 9 guinea pigs. The blood flow was measured with the microsphere method and

Glaucoma and Idiopathic Endolymphatic Hydrops
Annals of Otology, Rhinology & Laryngology, 1974Present concepts concerning endolymphatic hydrops and glaucoma production are similar. A study was undertaken to evaluate the possibility of identifying early glaucomatous changes in patients with symptoms suggesting endolymphatic hydrops. Precise tests are available for glaucoma but lacking for endolymphatic hydrops.

Endolymphatic Hydrops: Can it Be Controlled?
Annals of Otology, Rhinology & Laryngology, 1986While endolymphatic shunt procedures are conceptually logical, there are characteristics of underlying pathological conditions and host response that severely limit the probabilities of achieving functional shunts.

Pars Superioris in Endolymphatic Hydrops
Archives of Otolaryngology - Head and Neck Surgery, 1984A volumetric study was made of the endolymphatic compartments of the pars superioris (utricle and semicircular canals). Selected for this comparative study were 15 ears from subjects with unilateral endolymphatic hydrops, 15 contralateral ears, and 15 normal ears. There was an increase in the total volume as well as in the utricular volume.
