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

Cryosurgical treatment of endolymphatic hydrops
The Journal of Laryngology & Otology, 1989AbstractCryosurgery 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, 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.

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.

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.

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,

Endolymphatic Hydrops in Perilymphatic Fistula
Acta Oto-Laryngologica, 1987Cochlear hydrops was produced either by injecting artificial perilymph into the subarachnoid space or by sucking perilymph through the round window membrane. The animals were either vitally fixed immediately or kept alive for 1 to 3 months before fixation. Conventional celloidin embedding method was used for serial sectioning.

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 ...

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.

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 ...
