[Late results of stapedectomy after 15 years (author's transl)].

Stapedectomy in Otosclerosis in using polyethylene struts or stainless-steel wire protheses results in permanent correction of the postoperative gap. The use of stainless-steel wire protheses however is successful with 94% of the patients regarding the postoperative gap, compared to 89% of the patients in using the polyethylene struts. The postoperative decrement of bone conduction is statistically significantly lower in the stainless-steel wire protheses than in polyethylene struts.
