[Functional results of stapes surgery].

In 135 patients the functional results of stapedotomy and stapedectomy were controlled. As a rule, stapedotomy results were superior to stapedectomy results. Small hole stapedotomy using a 0.4 mm. teflon-wire piston yielded optimal sound transmission between 500-8000 Hz. In addition, this was the only technique to prevent cochlear damage at 4000 Hz and 8000 Hz.
