Perilymphatic hydrops: a human temporal bone study

The study included 17 temporal bones with non artifactually bulging round window membrane that indicated increased perilymphatic pressure. The specimens had been routinely processed and prepared for light microscopy. Pathological finding in the inner and middle ear reported. They are correlated with pathological changes in the internal auditory meatus and to details of the medical history. A correlation has been shown between perilymphatic hypertension, on the one hand, and potential cases of increased intracranial tension and a patent cochlear aqueduct, on the other hand
