Stapes mobilization in otosclerosis

We performed a retrospective chart study (including surgeon's notes and audiometric results) and an analysis of the archival temporal bones from a patient who had undergone surgery for stapes mobilization in both ears. The stapes footplate was submerged into the vestibule on the right (as a complication of surgery) and absent on the left. One interesting finding was that the patient's hearing had improved on the right despite the presence of the depressed footplate and that the air-bone gap had widened on the left despite the absence of complications on that side.
