摘要

本研究的目的是在中耳有限元模型中探讨外耳根韧带和包括韧带对鼓膜和镫骨足板位移的影响。模拟三种情况:一种不含韧带，一种包括后隐韧带和前外阴韧带，另一种包括上外阴韧带和隐韧带。当声压级(SPL)为90 dB时，在1024hz频率下对鼓膜进行激励，可获得0.023 μm的镫骨底板最大位移。计算结果与文献中的实验测量结果进行了验证。综上所述，我们的结果表明，上韧带是最有利于准确表示中耳频率响应。我们的结果与人类颞骨实验数据和其他有限元研究结果非常吻合。

A computational study of ligaments effect in middle ear chain anatomy behavior

The aim of this study is to investigate the effect of mallear and incudal ligaments to the tympanic membrane and the stapes footplate displacement in a finite element model of the middle ear. Three cases were simulated: one without the ligaments, one including the posterior incudal and the anterior mallear ligaments and one including in addition the superior mallear and incudal ligaments. A maximum stapes footplate displacement 0.023 μm was observed at a frequency 1024 Hz by exciting the tympanic membrane at a sinusoidal sound pressure level (SPL) of 90 dB. The computational results were validated with experimental measurements from the literature. Concluding our results show that the superior ligaments are most beneficial for an accurate representation of the middle ear frequency response. Excellent agreement is observed between our results and human temporal bone experimental data and other finite element studies.
