摘要

摘要: 目的:研究锤骨上韧带与锤骨前韧带固定对中耳传声的影响。方法:采用中耳结构正常成人颞骨显微CT扫描成像建立正常中耳有限元模型后,调整弹性模量建立锤骨上韧带与前韧带固定模型。计算锤骨上韧带与前韧带在固定与分离两种状态下对鼓膜与镫骨底板振动的影响,反应两种状态下对中耳传声的影响。结果:锤骨上韧带固定和锤骨上韧带与锤骨前韧带同时固定对鼓膜、镫骨底板位移振幅影响最大,主要集中于中低频区。锤骨前韧带固定导致镫骨底板于1~2 kHz间位移振幅轻度增高达3 dB;锤骨上韧带固定、锤骨上韧带和锤骨前韧带同时固定对镫骨底板在 0.5~1.0 kHz影响最明显,分别最大减小4 dB和6 dB;而锤骨上韧带和锤骨前韧带分离对镫骨底板振动基本无明显影响。结论:锤骨上韧带固定和锤骨前韧带固定对鼓膜和镫骨底板影响不同。锤骨上韧带固定对鼓膜、镫骨底板振动减小;锤骨上韧带、锤骨前韧带同时固定对镫骨底板影响最大;而锤骨上韧带和锤骨前韧带分离对镫骨底板振动基本无明显影响。

Abstract: Objective: To study the effect of fixation of superiormallear ligament (SML) and anterior mallear ligament(AML) on the middle ear transfer function.Method: A middle ear finite element model was established using micro-CT scanning from an adult temporal bone with normal middle ear structure. And the fixation model of SML and AML were established by changing its Young's modulus. Calculation of fixation and detachment of the two ligaments on the middle ear transfer function.Result: Displacement of tympanic membrane and stapes footplate was decreased significantly in case of fixation in both AML and SML, especially in the low frequency region.The SML fixation increased the amplitude of the stapes footplate by 3 dB between 1-2 kHz. In case of SML fixation along and both the SML and AML all fixation, the vibration of the stapes footplate was decreased obviously by 4 dB and 6 dB, respectively. By contrast, detachment of the SML and AML have little effect on the displacement of the stapes footplate.Conclusion: It is different that the effect of AML and SML on the vibration of the tympanic membrane and the stapes footplate. The SML fixation decreased the displacement of tympanic membrane and stapes footplate. Both the SML and SML all fixated decrease the stapes footplate significantly.But, there is little effect of the detachment of SML and AML on the displacement of the stapes footplate.
