[Otosclerosis involving the capsule and inner ear. Morphological findings (author's transl)]

The problem of otosclerotic inner ear damage is considered on the basis of morphological findings. It is pointed out that the disease of the otic capsule certainly also affects the underlying sense organ. This arises through disturbance of the perilymphatic electrolytes, venous stasis and thus changes in the circulation, disturbed regulation of endolymph and, more rarely, the direct effect of the focus on the auditory nerve or calcification of the mobile membranes.
