STAPEDIAL surgery has the aim of creating or, more frequently, restoring the stapedial mobility required for the transmission of sound across the middle ear. In general, as attested by a large number of clinical-statistical studies, normal middle ear function is restored to a high degree in a great majority of cases.

Using an empirical approach, a variety of surgical techniques to improve stapedial function has been developed over the years by otologic surgeons. Most of these techniques achieve approximately equal degrees of success, although the reason is not often apparent. Investigations have been largely confined to surgical-anatomical studies,1-3 and to the determination of the surgical risk.4-7 The fate and tissue tolerability of various materials used for stapedial substitution were made the subject of further studies.8-11 However, comparatively few efforts have been made toward the assessment of the purely physical factors involved in stapedial replacement.12 The results
