[The finite element study on zygomatic injury by impact in child].

Objective: The purpose of this study was to establish the constructive of craniofacial suture in the three-dimensional finite element model of craniofacial complex in child, to analyse the response procedure of the zygomatic impact, to explore the biomechanics characteristic of the children craniofacial trauma.

Methods: A 7-year-old female was adopted for study The complex cranial geometry was measured from a series of two-dimensional CT images. The multi-lay spiral CT scans were transformed with a self-developed preprocessor into a finite element mesh.

[Suppositional sutural construction and application in the three-dimensional finite element model of craniofacial complex].

Objective: The purpose of this study was to explore suppositional sutural construction and protraction in the three-dimensional finite element model of craniofacial complex.

Methods: Combining spiral CT scanning technology with the three-dimensional finite element method, three-dimensional FEM model of craniofacial complex was developed for analysis. In the model, craniofacial sutures were constructed through the MSC.
