Original Abstract

Summary: The analysis of the mechanics of the normal middle ear and of the middle ear with ossicular prosthesis is performed. The creation of the finite element model of the middle ear is described. The model of the normal ear includes external ear canal, tympanic membrane, ossicle chain with joints to oval window in the enter of cochley. The model of prosthesis simulates T-like type of the commercial product. The amplitude of the stapes footplate velocity and the amplitude of pressure excitations in cochley were evaluated for different manners of prosthesis fixation.
