The serious menace of chronic progressive deafness and the frequency with which otosclerosis, spongifying of the labyrinth capsule, appears to be the underlying pathologic cause has impressed us more and more as the study of these patients, extending over a period of years, has served to verify the correctness of an earlier, more or less tentative diagnosis.
