“…These diagonals can be measured directly with calipers or a flexicurve, from a 2D photograph, from a thermoplastic band, or from a 3D image. (Hutchison et al, 2005, van Vlimmeren et al, 2006, Atmosukarto et al, 2010, Schaaf et al, 2010a, Aarnivala et al, 2014, Skolnick et al, 2015 This index has also been termed the Cranial Vault Asymmetry Index (CVAI) and Oblique Diagonal Difference Index (ODDI), but in this study we use the term Oblique Cranial Length Ratio (OCLR). (Hutchison et al, 2005, van Vlimmeren et al, 2006, Schaaf et al, 2010b The often-cited problem with diagonal measurements is that they only quantify cranial symmetry on a single plane.…”

“…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]. In healthy infants plagiocephaly with the highest incidence of 20% at three to four months of age has been found to resolve to 3.3% up to the age of two years [16,21].…”

“…Cephalic index (CI) is the ratio between skull breadth and skull length multiplied by 100% and oblique cranial length ratio (OCLR) represents the ratio of the longer to the shorter diagonal measured at an angle of 40 degrees from the sagittal midline multiplied by 100% [15]. The cutoff point for brachycephaly was CI > 90%, and for plagiocephaly OCLR ≥ 106% with grading to severe (≥112%), moderate (≥108% and <112%), mild (≥106% and <108%), or none (100% < 106%) [15][16][17][18]. Clinical and dental examination of the children was made by a pediatrician and dentists investigators, who knew the group of the cases but did not know the existence of DP at examination.…”

Developmental dysplasia of the hip (DDH) may require early abduction treatment with infants sleeping on their back for the first few months of life. As sleeping on back is known to cause deformational plagiocephaly, we assessed school age children treated for dislocation or subluxation of the hip-joint in infancy. Plagiocephaly was analyzed by using cephalic index (CI) and oblique cranial length ratio (OCLR) as anthropometric measurements from 2D digital vertex view photographs. Six of the 58 (10.3%) DDH children and only one of the 62 (1.6%) control children had plagiocephaly (p = 0.041). Furthermore, cross bite was found in 14 (24.1%) of the DDH children and in 7 (10.3%) of the control children. Developmental dysplasia of the hip in infancy was associated with cranial asymmetries and malocclusions at school age. Preventive measures should be implemented.Keywords: developmental dysplasia of the hip (DDH); plagiocephaly; brachycephaly; cephalic index (CI); oblique cranial length ratio (OCLR); 2D-imaging; cross bite

Objective: The aim of the study was to determine the intra-and inter-reliability for measuring infants with plagiocephaly and brachycephaly with a craniometer when using a marked headband as landmarks. Subjects: Six physiotherapists and eight infants participated in the study. Methods: The physiotherapists measured all infants twice; each infant was measured with the same headband and craniometer. The physiotherapists were blinded to measurements carried out by their colleagues. The infants with their parents changed places in the room to minimize the possibility that the physiotherapists would remember their first measurements of any infant. Results: There was a high intra-and inter-reliability, for intra-reliability ICC 0.96 to 0.99 and for inter-reliability ICC 0.98. Conclusion: It is possible to achieve a high intra-and inter-reliability when using a headband and craniometer when measuring cranial vault asymmetry for plagiocephaly and cephalic ratio for brachycephaly.
