Ultrastructure of the endolymphatic sac in two-phase endolymphatic hydrops in the guinea pig

open access: yes, 1999
Two-phase endolymphatic hydrops is a subtle experimental model for Meniere's disease. Chronic dysfunction of the endolymphatic sac, induced by dissection of the most distal part without causing damage to the intermediate part, is combined with increased ...

Perilymphatic and endolymphatic pressures during endolymphatic hydrops

open access: yesEuropean Archives of Oto-Rhino-Laryngology, 2003
We analysed the fluid pressure in the perilymphatic and endolymphatic spaces of the cochlea in eight guinea pigs after endolymphatic hydrops (EH) was surgically created. The control experiments were done in the opposite ears. EH was histologically confirmed after the conclusion of the pressure measurements.

Animal models of endolymphatic hydrops

American Journal of Otolaryngology - Head and Neck Medicine and Surgery, 1982
Endolymphatic 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.

Two-phase Endolymphatic Hydrops: A New Dynamic Guinea Pig Model

open access: yesActa Oto-Laryngologica, 1997
The classical guinea pig model for Meniere's disease, in which endolymphatic hydrops was achieved by destruction of the endolymphatic sac and obliteration of the endolymphatic duct, is a non-physiological profound model with shortcomings in relation to ...

Endolymphatic Hydrops in Children

ORL, 2010
Apart from clinical observations of Ménière’s disease in children, there have only been a few histological descriptions of endolymphatic hydrops (EH) as an incidental finding in children. In this paper we report on the incidence of EH in temporal bones of children.

Posttraumatic Endolymphatic Hydrops

Archives of Otolaryngology, 1977
A case of posttraumatic endolymphatic hydrops that was confirmed by a positive glycerin test is reported. Although head trauma has been implicated as a cause of hydrops, few such cases are reported in the literature. Careful consideration of perilymphatic fistula must be accorded before a diagnosis of posttraumatic hydrops is made.

Pathology of endolymphatic hydrops

The Journal of Laryngology & Otology, 1980
The term 'endolymphatic hydrops' is not a definitive diagnosis since the condition occurs in a variety of otological disorders. Endolymphatic hydrops was found in 57 ears (9 per cent) of the 703 temporal bones in the collection of the Ear Research Institute, Los Angeles.

Auditory biophysics of endolymphatic hydrops

Journal of Vestibular Research, 2021
Audiological tests in patients with Menière’s disease reveal abnormal patterns relevant for diagnostic purposes with some success. Electrocochleography, otoacoustic emissions and immittance measurements share a moderate sensitivity but a good specificity.
