Alleviating abnormal stress on compressed cranial sutures: a potential mechanism for treating and preventing deformational plagiocephaly.

ABSTRACT:

Background

Abnormal stress in cranial sutures is strongly related to deformational plagiocephaly (DP) and is responsible for morphological changes in the skull, facial asymmetry, and abnormal facial tension. To evaluate the effect of biomechanical therapy on cranial sutures of DP we performed in silico analysis of normal skull in the supine position (Model 1), DP in the supine position (Model 2), and DP wearing moulding helmet (Model 3).

Methods

By utilizing 3D point cloud data, we generated finite element models (FEMs) and developed 14 cranial sutures. We evaluated the mechanical causes of the continuous progression of moderate to severe DP by comparing the Von Mises Stress (VMS) distributions of 14 cranial sutures between Model 1 and Model 2, and used the same method to co
