Abstract

In this paper, we present a statistical study into skull deformations caused by positional plagiocephaly. We also consider the hardware used for the assessment of both severity and treatment. State-of-the-art external imaging hardware is employed to assess the three-dimensional geometry of the cranium and face of 69 affected babies. The hardware used for most of this study is based on projected-pattern range finding, although we also experiment with photometric stereo techniques.

We then explain how the severity of the condition can be parameterised, based on the 3D data, using the Extended Gaussian Image (EGI) construction. The EGI is a method of compactly representing the overall geometry of surface (unlike existing metrics used in plagiocephaly), based on its distribution of surface gradients. In this study, we calculate EGIs for both the face and cranium of each patient. We then deduce metrics to parameterise cranial distortions and facial asymmetries. A clear but fluctuating relationship between facial asymmetry and cranial deformation was found. Our results point towards an improvement in both metrics through treatment by banding, although a more detailed study with a control group will be needed in future work.
