Innervation of the Endolymphatic Sac
Archives of Otolaryngology - Head and Neck Surgery, 1992Previous studies suggest that the endolymphatic sac plays an important role in the homeostasis of endolymph. Factors that influence blood flow in the sac may affect its function. This blood flow may be influenced by autonomic innervation; however, no such innervation has been demonstrated.

Archives of Otolaryngology - Head and Neck Surgery, 1969
THE SURGICAL treatment of Meniere's disease must be based as far as possible on physiopathological concepts and must take into account all the anatomical and pathological data published to date. Meniere's disease corresponds to an increase in the pressure of the endolymph in comparison with that of the perilymph. It is, therefore, probably conditioned

Presence of Glycosaminoglycans in the Endolymphatic Sac
Acta Oto-Laryngologica, 1997Earlier morphological investigations have revealed that the endolymph, which is present in the endolymphatic sac (ES) seems to differ from that found elsewhere in the labyrinth, in that it contains a stainable substance. Histochemical investigations indicate that this substance is rich in glycosaminoglycans (GAGs).

Endolymphatic Sac Tumours: Surgical Management
The Journal of Otolaryngology, 2006Endolymphatic sac tumours (ELSTs) have been known as an individual tumour entity only since 1984. ELSTs may occur either solitarily and sporadically or as a hereditary manifestation associated with von Hippel-Lindau (VHL) disease. The latter association was first observed in 1992 and confirmed by molecular genetic analysis of the VHL gene.

Calcium Transport in the Endolymphatic Sac
ORL, 2010Ca++ 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, 1981AbstractThe 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, 1991The 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, 1966FOR 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, 1989AbstractThe 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, 1979AbstractSince 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 ...
