In performing the operation for mobilization of the stapes, it is often necessary to remove a portion of the bony posterior canal wall that overhangs the incus and stapes. To facilitate the removal of this bone, the instrument shown here was devised. The instrument has a thin lip that fits under the overhanging edge of the posterior canal and a cutting edge which bites out the bones between the two blades. (Fig. 2.)
This instrument was designed by me and manufactured by D. Mueller & Co., Chicago.
