Abstract
We performed 20 operation of stapedectomy during March 1984-February 1988 sixteen cases were on the small fenestra stapedectomy (SFS) and 4 cases were total stapedectomy. We studied the hearing level in both the pre and post operative situations and complications, etc, on 16 cases of small fenestra stapedectomy. In our results, we concluded that SFS is safe and effective surgical procedure to increase hearing efficiency with little dizziness and few complications. We feel this will be a standard surgical procedure in near future in Japan.
