Figure 6

Example of “jamming” of the stapes footplate due to adjacent otosclerotic lesion in the otic capsule. A) Medium power image through the stapes footplate demonstrates an otosclerotic focus (“OF”) anterior to the oval window. B) High power image of the anterior stapedo-vestibular joint space showing point fixation, but no extension of otosclerosis into the stapes itself. C) High power image of the posterior stapedo-vestibular joint space showing “jamming”, or posterior displacement of the stapes footplate so that it contacts the posterior margin of the oval window.
