本文介绍了一种新的数值方法,用于估计鼓室成形术前的听力恢复效果,使用有限元谐波振动分析。这种方法使得有可能提出一种用于恢复传导性或耳蜗性听力损失的新的医学治疗。首先,在CT扫描数据的基础上,建立精确的中耳几何模型,包括健康型模型和鼓室成形型模型。然后,利用三维有限元简谐振动分析,阐明了镫骨位移在声传导中的频率响应特性。根据研究结果,我们提出可以通过比较重建模型与健康人镫骨位移的差异来估计听力恢复效果。
In this paper, we introduce a new numerical approach for estimating the hearing restoration eect prior to the tympanoplasty operation using the nite element harmonic vibration analysis. This kind of approach makes it possible to propose a new medical treatment for the recovery of conductive or cochlear hearing loss. First of all, precise geometric models of the middle ear, including healthy type model and tympanoplasty type models, are constructed on the basis of the computerized tomography (CT) scanning data. Then, frequency response characteristics of the stapes displacement in sound conduction are claried using the three-dimensional nite element harmonic vibration analysis. Based on the investigation results, we propose that the hearing restoration eect can be estimated by a comparison of the dierences in the stapes displacement between the reconstruction model and the healthy subject.
