Endolymphatic Hydrops: An Overview and Classification
Annals of Otology, Rhinology & Laryngology, 1983Endolymphatic hydrops (EH) is a pathological condition which is the final common manifestation of a variety of otologic insults. In this paper we develop a classification which, on the basis of clinical and pathological data, distinguishes symptomatic and asymptomatic forms. Clinical case histories and temporal bone studies are presented to illustrate

Annals of Otology, Rhinology & Laryngology, 1978
Delayed endolymphatic hydrops is a disease entity that can be differentiated from Meniere's disease. Typically it occurs in patients who have sustained a profound hearing loss in one ear, usually from infection or trauma, and then after a prolonged period of time develop either episodic vertigo from the same ear (ipsilateral delayed endolymphatic ...

Effect of Diuretics on Endolymphatic Hydrops
Acta Oto-Laryngologica, 1986The effect of diuretics on endolymphatic hydrops, which was produced by obliteration of the endolymphatic duct and sac in guinea pigs, was determined by statistical analysis of volumetric changes in the scala media. When acetazolamide was administered orally at 159 to 434 mg/kg per day for a period of 30 days, endolymphatic hydrops did not reach the ...

Endolymphatic hydrops perspectives 2012
Current Opinion in Otolaryngology & Head and Neck Surgery, 2012Endolymphatic hydrops remains a significant cause of morbidity secondary to vertigo, hearing loss, and tinnitus. The purpose of this report is to summarize the most clinically relevant publications on endolymphatic hydrops over the past 2 years.Hydrops has historically been a diagnosis of exclusion, but recent efforts has shown a role for MRI with ...

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.

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 ...

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.

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.

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 ...
