DURING stapedectomy it is not always possible to visualize the exact localization and precise morphology of the lesion which fixes the stapes at the edge of the oval window especially in the case of small otosclerotic foci.
At a high enlargement the larger foci appear quite evident under the operating microscope, but the optical conditions do not permit a detailed examination. Sometimes only by removing the stapes can the surgeon assess the approximate extent of the focus and the degree of fixation of the stapes. However, this procedure must be carried out in the shortest possible time, which never permits an accurate examination.
After the operation a precise description can be made by examining the removed fragments with a dissecting microscope at a higher enlargement. For this reason we consider it necessary to examine thoroughly the removed fragments in order to compare these observations with those of the surgeon.
