Ninety-four consecutive stapedectomy cases using the Robinson stainless steel prosthesis are compared with 100 consecutive cases using the House stainless steel wire prosthesis. The air-bone gap was closed to within 10 dB in 94% of the cases with the Robinson prosthesis and in 88% of the cases using the House stainless steel wire prosthesis. There appeared to be no difference in the improvement at 2,000 and 4,000 cycles between the two techniques and the results were the same. Statistical study revealed there is no significant difference in the two techniques and there is no other variable. FOLLOWING Mendel Robinson's' excellent report on his results of stapes surgery using the Robinson stainless steel and Robinson Teflon stapes prostheses, one of the authors (E.L.D.) began using the Robinson prostheses routinely. It has been six years since this technique change, and the authors felt the need for a review of results. The purpose of this paper is threefold: (1) tabulation of closure results of the techniques used by two of the authors, (2) a comparison of these results and thus a comparison of the efficacy of the two techniques, and (3) a comparison of our results with the previously reported results of various techniques incI u d i n g Robin so n's.
