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.
