ossicular 链的损害是损害听觉的感觉的普通耳朵疾病。人的耳朵的一个全面数字模型能提供健全传播的更好的理解。在这研究,我们建议合并运河,鼓膜的膜, ossicular 骨头,中耳悬带系带 / 肌肉,中耳洞和内耳液体的人的耳朵的一个三维的有限元素模型。数字分析被进行并且采用了预言中耳洞,锤骨柄缺点,砧骨的长过程的发育不全,和镫骨的脚的效果在健全传播上背叛。现在的有限元素模型被显示在预言人的耳朵的 ossicular 力学讲理。
Abstract Lesion of ossicular chain is a common ear disease impairing the sense of hearing. A comprehensive numerical model of human ear can provide better understanding of sound transmission. In this study, we propose a three-dimensional finite element model of human ear that incorporates the canal, tympanic membrane, ossicular bones, middle ear suspensory ligaments/muscles, middle ear cavity and inner ear fluid. Numerical analysis is conducted and employed to predict the effects of middle ear cavity, malleus handle defect, hypoplasia of the long process of incus, and stapedial crus defect on sound transmission. The present finite element model is shown to be reasonable in predicting the ossicular mechanics of human ear.
