C-wire hand drill for small-hole stapedectomy.
With the four-sided point of the C-wire hand drill there is less risk of footplate mobilization during small fenestra stapedectomy. The small fenestra stapedectomy is thought to cause less trauma to the vestibule and to pose less risk of aspirating vestibular contents than the stapedectomy that totally removes the footplate.
