Calcium Transport in the Endolymphatic Sac

ORL, 2010
Ca++ activity and DC potential were measured in vivo in the endolymphatic sac (ES) of guinea pigs by means of double-barrelled ion-sensitive microelectrodes. We found a positive DC potential of 14 mV and a Ca++ activity of 4.7 X l0––4M. Anoxia induced a decrease in the DC potential and an increase in Ca++ activity; however, no negative DC potential was

Surgery of the endolymphatic sac

The Laryngoscope, 1981
AbstractThe wide variation in reported success rates in endolymphatic sac surgery has been the subject of much controversy in literature. This series is a follow‐up of additional cases done since 1976 that were previously reported with 55% relief of vertigo on relatively long‐term follow‐ups of 24 months to 10 years.

Ultrastructure of the Endolymphatic Sac in the Mouse

Cells Tissues Organs, 1991
The ultrastructure of the endolymphatic sac (ES) in the mouse was examined by light and electron microscopy. This organ was divided into three parts: proximal, intermediate and distal. In the proximal portion of the ES, the epithelium consisted of thin squamous cells.

Surgery of the Endolymphatic Sac

Archives of Otolaryngology - Head and Neck Surgery, 1966
FOR this lecture in memory of George Morrison Coates, it is fitting to choose a subject that is in the forefront of otosurgical interest. It is easy to forget that in the beginning the operation that revolutionized otologic surgery, the one-stage fenestration operation, was vigorously opposed by nearly all of the leaders in otology.

Effects of amiloride on the endolymphatic sac

The Journal of Laryngology & Otology, 1989
AbstractThe effect of amiloride on the murine endolymphatic sac was investigated. The amiloride caused collapse of the lateral intercellular spaces in the endolymphatic sac epithelium and a subsequent mild endolymphatic hydrops. These changes indicated a decreased absorption of endolymph in the endolymphatic sac.

The endolymphatic sac: Anatomical considerations

The Laryngoscope, 1979
AbstractSince Portmann suggested surgical drainage of the endolymphatic sac in 1927, several similar procedures have been described. These procedures all share a common problem: the endolymphatic sac must be identified without injuring the labyrinthine structures or the facial nerve.Anson and Donaldson have provided the otologist with a detailed and ...

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 ...

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 ...
