| Outline of Final Research Achievements |
Ossicular tension is an important factor in the acoustic performance of incus and
incus-stapes replacement prostheses; length is the primary determinant of postinsertion tension in conventional, rigid prostheses. The purpose of this study was to determine whether a self-djusting prostheses con
taining a silicon sponge. Although the silicon sponge seems to decrease the effect of changes in prosthesis length between the malleus and stapes at low frequencies, improvement in sound transmission efficiency of the silicon sponge is needed.
