[Establishment and preliminary application of a laryngomalacia larynx three-dimension model].

Abstract

Objective:To establish and preliminarily apply a laryngomalacia larynx three-dimension finite element model. Method:The MIMCS software was employed to deal with the Dicom images of larynx CT scan by means of distinguishing material gray threshold of different tissues. 3D visualization model of larynx was also built by this software. Hyermesh software was used to handle the grid layout of larynx finite element model. Laryngeal structure parameter were added, and laryngeal mechanical analysis were carried out by Abaqus software in order to get von Mises stress. Result:A 3D model，which finely represent the morphological characteristics of laryngomalacia larynx was built using the finite element technology. Peak von Mises stress was observed to be higher in more severe laryngomalacia case. Conclusion:The 3D finite element model of the laryngomalacia larynx provides the foundation for further study．Peak von Mises stress may be a useful indicator of laryngomalacia severity assessment.
