[Innerearhydrops a result of disturbed endolymphcirculation (author's transl)].
By means of human temporal bone slides we want to demonstrate that interruption of the so-called longitudinal endolymphcirculation causes a hydrops ahead of the block. This fact, proven by animal experiments, we observed in human specimens. Predominant locations are the anatomic narrows of the endolymphatic system: Isthmus of the endolymphatic duct, utriculoendolymphatic valve Bast, ductus reuniens. The different possible pathohistological data are: bony obliteration of the ductus endolymphaticus, embolic closure within the isthmic portion of the endolymphatic duct, blockage of the utriculoendolymphatic valve by the distended utricle or perilymphatic connective tissue strands, angled ductus reuniens in perilymphatic fibrosis.
