摘要: 由于外科医生对于声带麻痹植入手术没有有效的预测,手术的失败率较高,因此采用有限元的方法进行术前模拟仿真。通过人体的喉部CT数据,使用Mimics软件提取声带与声门气管三维几何模型,然后导入到ANSYS-Fluent来模拟声带麻痹患者植入手术前后声带振动模式与喉部气流动态耦合特性,分析声门气管表面压力以及气流速度的变化情况。实验结果与临床统计数据进行分析与对比,推断运用有限元分析技术进行声带麻痹植入手术仿真模拟的研究方法合理可行,为手术方案提供了支持。

Abstract: As surgeons do not have effective prediction on the the implant surgery for vocal cord paralysis, resulting in high rate of failure, the finite element method was used for preoperative simulation. Through Computed Tomography (CT) data of larynx, the 3D geometric model of vocal cords and glottis trachea was extracted by Mimics, and then imported into ANSYS-Fluent to simulate the vocal vibration mode and airflow dynamic coupling characteristics before and after implanted surgery. The experimental data and clinical statistics data were compared to prove the feasibility of the finite element analysis techniques for implant surgery simulation of vocal cord paralysis. The experimental result can provide support for the design of surgery program.

Key words: vocal cord paralysis, three-dimensional reconstruction, finite element analysis, relevance validation
