Is the Endolymphatic Sac Always Accessible?
Otolaryngology–Head and Neck Surgery, 1985All 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.

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.

The Surgical Anatomy of the Endolymphatic Sac
Archives of Otolaryngology, 1977The 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, 1976The 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 ...

Endolymphatic sac decompression
2018This chapter discusses Thomsen, Bretlau, Tos, and Johnsen’s 1981 paper on Ménière’s disease and endolymphatic sac decompression compared with sham (placebo) decompression including the design of the study (outcome measures, results, conclusions, and a critique).

The endolymphatic sac lies in the bony niche of the posterior surface of the pyramid. It partly touches the dura mater of the posterior fossa. The endolymphatic sac communicates with the endolymphatic system through the endolymphatic duct. The epithelia of the sac are either squamous cell or cuboidal cell.

Modulation of the Endolymphatic Sac Function
Acta Oto-Laryngologica, 1991A 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

This section describes the technique of identifying the endolymphatic sac, decompressing the sac, and opening the sac for shunt placement. The authors do not endorse a specific procedure for hydrops. Surgery on the endolymphatic sac requires a complete simple mastoidectomy as outlined in the preceding section.

We present a case of a papillary tumour at the cerebellopontine angle in a 41-year-old man. He presented with left-sided facial and ear pain associated with dizziness, nystagmus and hearing loss. CT scan of the temporal bone showed a destructive tumour at the left cerebellopontine angle.
