Although the modern technique of otosclerosis surgery introduced by John Shea on 1st May 1956 has already been used throughout the world for almost fifty years it has not been possible to bring in line the differing opinions of surgeons concerning the optimum operation technique, the problems of the fenestration of the footplate, material and form of stapes replacement prosthetics and kind and place of their anchoring on the incus. Moreover, there is considerable disagreement among surgeons on a realistic evaluation of the findings of early and late results. During the last few decades otosclerosis surgery has become the hallmark of modern ear surgery and has been practiced in very highly specialized departments as well as in outpatient departments. The author, who has been very active in otosclerosis surgery since 1959-since 1979 with a modified personal technique-, wishes to prove that it is both meaningful and essential to modify the operation technique further, which is based on his own experiences and on more than 100 international publications. In this paper he presents his modified method, which has been tested on 1800 ears since 1979, as well as the results, achieved in this way.
