MIDDLE-EAR SCLEROSIS, OR ATROPHIC MIDDLE-EAR CATARRH. [PDF]
This condition depends on trophic changes and, in contrast to a multitude of clinical forms that have been described under various names, it has a comparatively simple pathology. The clinical appearances vary with the location and degree of the pathologic change and with the structure and tissue affected.
