Preventing deformational plagiocephaly through parent guidance: a randomized, controlled trial

Abstract

•Early parent guidance effectively reduces the prevalence and severity of DP and improves the cervical range of motion at three months. •Educating both parents and professionals about proper infant positioning on a national scale could help minimize public healthcare costs.

Plagiocephaly after Neonatal Developmental Dysplasia of the Hip at School Age

“…Just after birth 7.7% of healthy newborns have shown to have plagiocephaly and the amount increased to 11% when parents are guided for prevention of plagiocephaly, and to 31% without any guidance up to the age of three months [15,19]. Positional preferences or simple nursing habits after birth can cause development of deformational plagiocephaly or may provoke worsening of it [15,20].…”

Analyzing infant head flatness and asymmetry using kernel density estimation of directional surface data from a craniofacial 3D model

“…Head position standardization was based on the subject's facial area (cf. [4,22]). The facial 3D shell of the subject was first fitted to a fixed frame of reference by placing the point halfway between the inner corners of the eyes at the origin.…”

“…The transverse plane then passes through the origin and is perpendicular to the two other planes. In pose 2, the transverse plane goes through the origin and the midpoint of the line that connects the two tragion points located in the ears [4]. The coronal plane then passes through the origin and is set to be perpendicular to the two other planes.…”

“…Using all 99 head images, our asymmetry scores ( (10) and (11)) were next compared with two earlier proposals and clinical ratings. Volume ratio scores for the infant head data were available from a previous study [4], and we implemented ourselves the 2D histogram asymmetry scoring algorithm of Atmosukarto et al [12]. In the following, we refer to the volume ratio asymmetry score as VRAS and the 2D histogram asymmetry score as HAS.…”

“…A 3D image of the head can be produced using a stereo camera and an actual 3D geometric model can be obtained, for example, by laser scanning, or as in this study, using multi-camera photogrammetry (cf. [4][5][6][7]). A particularly active area of research has been the study of infant head deformations, such as deformational plagiocephaly and brachycephaly [2,8,9].…”
