Numerical Simulation of Human Middle Ear Based on Finite-Element Method

An accurate finite element model of the human middle ear provides better understanding of the mechanics of middle ear,and can be used for aiding the design of the implantable middle ear hearing devices.In this study,a three-dimensional finite element model of the human ear was constructed that included the tympanic membrane,ossicular bones and middle ear suspensory ligaments/muscles.This model was constructed based on a complete set of computerized tomography section images of a healthy volunteer's right ear by reverse engineering technology.The validity of this model was confirmed by comparing the motion of the tympanic membrane and stapes footplate obtained by this model with published experimental measurements on human temporal bones.The result shows that the model is reasonable in predicting the biomechanics of the human middle ear.
