Endolymphatic hydrops precipitated by haemodialysis
The Journal of Laryngology & Otology, 1990AbstractWe 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.

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).

The Vertigo of Endolymphatic Hydrops
Archives of Otolaryngology - Head and Neck Surgery, 1967THE VERTIGO of endolymphatic hydrops is of three types: the premonitory, the critical, and the residual. In a given case premonitory vertigo may or may not occur. When it does it is a valuable harbinger of more severe trouble to come. Regarded and diagnosed at this time as a labyrinthine symptom with a potentially grave future this premonitory ...

Experimental Endolymphatic Hydrops in the Rat
Archives of Otolaryngology - Head and Neck Surgery, 1986In the rat, the epithelial lining of the endolymphatic duct and sac, and the contents of the sac, showed remarkable differences in comparison with these structures in the guinea pig and man. Obliteration of the endolymphatic duct resulted in endolymphatic hydrops of varying severity in 55% of the rats, after survival times varying from one to five ...

Pathogenesis of Experimental Endolymphatic Hydrops
Acta Oto-Laryngologica, 1983The 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,

Effect of Fistulae on Endolymphatic Hydrops
Annals of Otology, Rhinology & Laryngology, 1975An 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.

Objectives: This study was designed to assess the correlation between the grades of endolymphatic hydrops and the blood-labyrinth barrier permeability in the affected ear in Meniere’s disease, following the administration of intravenous gadolinium ...

Perilymphatic and endolymphatic pressures during endolymphatic hydrops
European Archives of Oto-Rhino-Laryngology, 2003We 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.

Endolymphatic Pressure in Experimental Hydrops
Archives of Otolaryngology - Head and Neck Surgery, 1987Perilymphatic 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.

Diagnosis of Early Endolymphatic Hydrops [PDF]
Otolaryngology–Head and Neck Surgery, 2012 ObjectiveTo evaluate ear fullness as an early symptom of endolymphatic hydrops by relating it to enhanced SP/AP ratio on electrocochleography.MethodThe study that was conducted between January 2010 and January 2011 included 2 groups. Group I (20 patients) with normal hearing and complaint of ear fullness with no eustachian dysfunction and group II (10 ...
