A possible mechanism of the formation of endolymphatic hydrops and its associated inner ear disorders

Auris Nasus Larynx, 2020
The pathology of Meniere's disease (MD) is well established to be endolymphatic hydrops. However, the mechanism underlying deafness and vertigo of MD or idiopathic endolymphatic hydrops is still unknown.

Endolymphatic hydrops and otitis media

The Laryngoscope, 1979
AbstractClinical observation of patients with fluctuant sensorineural hearing loss following or occurring with chronic otitis media led to the hypothesis that endolymphatic hydrops can result from chronic otitis media. Illustrative case reports are described.

A Case Of Delayed Endolymphatic Hydrops

Auris Nasus Larynx, 1992
A 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

Endolymphatic hydrops precipitated by haemodialysis

The Journal of Laryngology & Otology, 1990
AbstractWe report a case of endolymphatic hydrops preceded by haemodialysis in the contralateral ear of a patient with known Menière's disease, and discuss the possible mechanism. It is suggested that the sudden decrease of plasma osmolality during haemodialysis acts as a reverse glycerol test.

Cryosurgical treatment of endolymphatic hydrops

The Journal of Laryngology & Otology, 1989
AbstractCryosurgery of the labyrinth, as a treatment of endolymphatic hydrops, was initially greeted with considerable enthusiasm, but has latterly received little publicity. That it still has a valuable role is demonstrated by this study of 69 patients who underwent labyrinthine cryosurgery over a 16 year period.

Endolymphatic Pressure in Experimental Hydrops

Archives of Otolaryngology - Head and Neck Surgery, 1987
Perilymphatic and endolymphatic pressures were consecutively measured by means of a servomechanical nulling pressure system through the round window and basilar membrane one to 2.5 months after obliteration of the left endolymphatic sac and duct in seven guinea pigs.

The Correlation Between Endolymphatic Hydrops and Clinical Features of Meniere Disease

The Laryngoscope, 2020
The purpose of this study was to investigate the grades of endolymphatic hydrops determined by gadolinium‐contrast magnetic resonance (MR) and correlation to the clinical features in patients with Meniere disease.

Effect of Fistulae on Endolymphatic Hydrops

Annals of Otology, Rhinology & Laryngology, 1975
An experiment was performed on 31 guinea pigs to study the effect of fistulae of the horizontal canal, superior canal, common crus, and utricle on the course of experimentally induced endolymphatic hydrops. The effect of fistulae on corresponding parts of normal ears was also studied in an additional 17 animals.

Comparison between high-resolution 3D-IR with real reconstruction and 3D-flair sequences in the assessment of endolymphatic hydrops in 3 tesla

Acta Oto-Laryngologica, 2020
Background The main sequences used to assess degree of endolymphatic hydrops (EH) are the 3D- inversion-recovery (IR) with real reconstruction and the 3D- fluid-attenuated inversion recovery (FLAIR).

Pathogenesis of Experimental Endolymphatic Hydrops

Acta Oto-Laryngologica, 1983
The protein content and the d.c. potential of the endolymph differs in the various parts of the endolymphatic space (cochlea, utricle, semicircular canals and endolymphatic sac) as also does the ion composition (chloride, potassium, sodium). 12 months after obliteration of the endolymphatic sac and duct in guinea pigs the d.c. potential falls, whereas,
