A contribution to the pathogenesis of otosclerosis.
In a histochemical and electron microscopical study the pathogenesis of otosclerosis was investigated. The morphological changes in the extra- and intracellular space indicated a complex metabolic disturbance of all tissue components. The observed chondrocytic chondrolysis stressed the role of the cartilage remnants in the otic capsule as an etiological factor. There was morphological evidence of a superimposed enzymatic defect.
