[The three-dimensional simulation of arytenoid cartilage movement].
OBJECTIVE
Exploring the characteristics of arytenoid cartilage movement.


METHODS
Using Pro/ENGINEER (Pro/E) software, the cricoid cartilage, arytenoid cartilage and vocal cords were simulated to the three-dimensional reconstruction, by analyzing the trajectory of arytenoid cartilage in the joint surface from the cricoid cartilage and arytenoid cartilage composition.


RESULTS
The 3D animation simulation showed the normal movement patterns of the vocal cords and the characteristics of vocal cords movement in occasion of arytenoid cartilage dislocation vividly.


CONCLUSIONS
The three-dimensional model has clinical significance for arytenoid cartilage movement disorders.
