Development of Diagnosis Method of Stapes Fixation

Abstract

In tympanoplasty, it is essential to understand the condition of the stapes. However, it has been difficult to evaluate stapes mobility in routine measurement. In this study, aiming at the clinical usage in the future, a new measuring system, which enables to measure the stapes mobility quantitatively and easily, has been developed, and the relationships between the load and displacement of the normal and artificially fixed stapes in the guinea pigs and rabbits were examined.
