Experimental Hyperactivity of the Endolymphatic Sac

Audiology and Neurotology, 2013
Injury to the endolymphatic sac may play an important role in the pathogenesis of Ménière’s disease, an inner ear disorder characterized by hearing loss, tinnitus and attacks of vertigo. Isoimmunization of 16 inbred Lewis rats with a crude endolymphatic sac extract and complete Freund’s adjuvant induced hyperactivity of the endolymphatic sac. One group

The Surgical Anatomy of the Endolymphatic Sac

Archives of Otolaryngology, 1977
The endolymphatic sac (ELS) and vestibular aqueduct (VA), which play a notable role in the pathogenesis of endolymphatic hydrops and Meniere disease, were identified in all anatomic and tomographic materials. More than 100 temporal bones were used for microdissection, tomography, and plastic molds.

Destruction of the endolymphatic sac in the cat

The Journal of Laryngology & Otology, 1976
The endolymphatic duct and sac were destroyed by drilling in a cat that was sacrificied after 2 3/4 years. Histological examination of the temporal bones showed marked endolymphatic hydrops; degeneration of the stria vascularis in the upper coil; degeneration of the organ of Corti and spiral ganglion in the upper and middle coils; and degeneration of ...

Gene expression of the endolymphatic sac

Acta Oto-Laryngologica, 2011
The endolymphatic sac is part of the membranous inner ear and is thought to play a role in the fluid homeostasis and immune defense of the inner ear; however, the exact function of the endolymphatic sac is not fully known. Many of the detected mRNAs in this study suggest that the endolymphatic sac has multiple and diverse functions in the inner ear.The

Is the Endolymphatic Sac Always Accessible?

Otolaryngology–Head and Neck Surgery, 1985
All surgical manipulations of the endolymphatic sac have a common requirement: to identify the intradural part. We studied the position of the intradural endolymphatic sac in relation to the posterior semicircular canal, the sigmoid sinus, the retrofacial air cell tract, and the jugular bulb in 50 temporal bones.

Identification of Substances in the Endolymphatic Sac

Acta Oto-Laryngologica, 1994
The composition of the contents of the endolymphatic sac (ES) has yet to be fully defined. Carbohydrates have been found in the ES of human fetuses and animals but not identified in the adult human ES. In the present study, celloidin was removed from previously prepared human temporal bone sections and a histochemical method was used to detect ...

The Vascular Supply of the Endolymphatic Sac

Acta Oto-Laryngologica, 1979
The vascular anatomy of the endolymphatic sac in guinea pigs was examined following intravascular injection of silicone rubber (Microfil). Methacrylate resin of low viscosity (Mercox) was used to obtain vascular corrosion casts for scanning electron microscopy, which allowed more accurate differentiation between arteries and veins.

Drug Permeability of the Endolymphatic SAC

Annals of Otology, Rhinology & Laryngology, 1987
Intravenously injected kanamycin sulfate (KM) was located in the endolymphatic sac (ES) of guinea pigs by an immunohistologic method. Kanamycin sulfate had passed through the capillaries in the subepithelial layer and reached the epithelial layer as early as 1 minute after injection.

Modulation of the Endolymphatic Sac Function

Acta Oto-Laryngologica, 1991
A method for inducing a partial dysfunction of the endolymphatic sac and its effect was investigated. Acetazolamide as well as amiloride caused collapse of the lateral intercellular spaces in the endolymphatic sac epithelium and a subsequent mild endolymphatic hydrops. These changes indicate a decreased absorption rate of endolymph in the endolymphatic

Effects of endolymphatic sac decompression surgery on endolymphatic hydrops

Acta Oto-Laryngologica, 2013
The present findings suggest that complete control of vertigo after endolymphatic sac decompression surgery (ESDS) does not always depend on improved vestibular function or reduced endolymphatic hydrops. Vertigo control is, however, associated with hearing stability.Among surgical treatments for intractable Meniere's disease, ESDS is performed to ...
