More basic knowledge of stapes fixation is vital if we are to improve the techniques now used to alleviate the conduction deafness of otosclerosis. This paper will describe the ankylosed and partially fixed specimens available to me, but much more histological material is needed for a thorough understanding of the many ways that the stapes can be hampered in its movements by otosclerosis as well as by other types of disease. The recent paper by Rüedi1 of Zurich, describing some 80 cases of otosclerosis, will help, but even this is not complete. Nowhere in the world do we have enough autopsy material, with good case histories and audiometric data. Until these are obtained we must carefully restudy the specimens and published data available.
Otosclerosis may be associated with either fibrous or bony changes in the niche of the oval window. However, the osteoporosis and osteogenesis in the
