  • Look Inside

Authors examined 19 stapeses obtained during surgery for otosclerosis under light and differential interference contrast microscopes. Active focus was found in 3 stapeses. Sclerotic bone formation was found in the anterior edge of the footplate in 11 ears. Bone formation at both anterior and posterior edges was found in two stapes of 7 and 8 years old girls. This bony tissue showed the characteristics of carti-lage. Calcification of a part of anterior annular cartilage was found in 3 ears. Compared to a similar histological report in Europe, the present bony changes were generally small and inactive. Racial difference may present in the nature of otosclerosis.
