“…It was possible to determine craniometer measurements as relative rather than absolute values and use them for screening. Two studies comparing 3DS and caliper measurements of the same infants have been published, and both reported a strong correlation between 3DS and caliper measurements [22,23]. These results show that cranial geometry and screening for DP and BC are possible, even when using a caliper-based measurement method.…”

We assessed a method for screening the cranial shape of 1-month-old infants using a simple measuring instrument instead of a three-dimensional scanner. The Mimos craniometer was used to measure cranial length, cranial width, and two diagonal lengths to calculate the cranial index (CI) and cranial asymmetry (CA). We defined a CI > 90% as brachycephaly and CA > 5 mm as deformational plagiocephaly (DP). Intra- and inter-examiner accuracy analyses were performed on a dummy doll and 1-month-old infants. The measurements of healthy 1-month-old infants were compared with previously reported three-dimensional scanner measurements. Intra- and inter-rater measurements showed good accuracy; diagnostic accuracy comparisons of brachycephaly and DP using a three-dimensional scanner showed kappa values of 1.0 and 0.8, respectively. Comparisons were made among 113 infants matched for day-age at the date of measurement; there were no significant differences in the CI (85.0% vs. 85.2%, p = 0.98) and CA (5.9 mm vs. 6.0 mm, p = 0.48) between the scanner and caliper measurements, nor in the prevalence of brachycephaly (12.4% vs. 17.7%, p = 0.35) or DP (58.4% vs. 56.6%, p = 0.89). This simple measurement method using calipers and bands was useful in screening for brachycephaly and DP in 1-month-old infants.

“…For units requiring more precise measurements, 3D scanning is preferred, as it provides detailed parameters for diagnosing abnormal head shape and facilitates personalized helmet customization. The combined approach aligns with China’s national standards for children’s head measurement ( 16 ). Of course, other diagnostic methods may be chosen based on clinical needs ( 27 , 28 ).…”

“…However, with the increased focus on the health of infants, there has been a growing awareness of the importance of head shape. Despite a decade of research ( 4 , 13 - 16 ) on infant head shape in China, there is still a need for further improvement in medical staff’s understanding of children’s head shape and its impact on health. Projects related to children’s growth, development, vision, and hearing screening are being widely implemented ( 17 - 21 ).…”

Background Head shape problems are common in infancy and early childhood, and thus their early identification and management can benefit the health of children. This study aimed to investigate pediatric healthcare professionals’ existing knowledge of children’s head shape abnormalities and their associated effects in China, providing guidelines for future clinical interventions, training, and interdisciplinary collaboration. Methods We conducted a survey among pediatric medical staff, encompassing various age groups, genders, hospitals, and professional levels. The electronic questionnaire queried respondents’ basic information, knowledge pertaining to head shape issues, diagnosis and treatment approaches, and the clinical development status of head shape problems. All surveys and data collection were conducted anonymously. Results A total of 214 valid questionnaires were collected. Differences in the level of understanding among medical staff regarding head shape issues were observed. Medical staff in tertiary care facilities showed the highest proficiency in diagnosing and treating positional plagiocephaly and cranial asymmetry (P<0.05), while those in primary care facilities exhibited the lowest competency in diagnosing head shape abnormalities (P<0.05). Most medical staff had a partial understanding of specific aspects of head shape issues, such as identifying high-risk individuals (n=144, 67.29%), making diagnoses (n=176, 82.24%), and understanding the consequences (n=151, 70.56%), with no significant differences across medical facilities of various levels. Additionally, 99.07% (n=212) of the medical staff believed that head shape measurements should be included as a routine component of pediatric physical examinations, and 75.23% (n=161) incorporate head shape assessment as part of their routine physical examination. Furthermore, 91.12% (n=195) of the medical staff received consultations on children’s head shape issues, with a higher prevalence in secondary and tertiary care facilities. Finally, 93.97% (n=201) of the participants expressed the need for further education and knowledge on pediatric head shape, with no significant differences across medical facilities of various levels. Conclusions There is a limited understanding among medical personnel in China regarding children’s head shape issues. Therefore, it is imperative to enhance training and educational initiatives for medical staff in China, with the goal of enhancing their awareness and knowledge regarding children’s head shape problems.

“…The cranial index is measured using cranial calipers once the infant’s hat is removed and calculated by dividing the width of the infant’s head by the length in centimeters, and then multiplying by 100 to be reported as a percentage [ 13 ]. This method of measurement has high intra-rater reliability [ 3 , 23 ] and demonstrates high correlation (r = 0.79–0.98) with 3-dimensional scanning technology [ 24 ]. In published studies, dolichocephaly has been defined as a CI of 76% or less [ 2 , 13 ].…”

Objective The objective of this exploratory study was to assess the potential impacts of two different continuous positive airway pressure (CPAP) devices on preterm infant head shape and circumference. Study design Twenty infants born at <32 weeks gestational age requiring CPAP support were enrolled. Ten infants used the Hudson RCI Nasal Prong CPAP device and 10 infants used the Fisher-Paykel CPAP device. Infant Cranial Index (CI) and head circumference (HC) were collected weekly as well as infant gestational age at birth, and total number of days on CPAP. Results At baseline, average total birthweight of infants was 1021 grams (SD = 227 grams), average gestational age was 26.9 weeks (SD = 1.80), mean CI was 79.7 cm (SD = 5.95), and HC was 10.2 cm (SD = 0.92). Days on CPAP ranged from 16 to 63 days, with an average of 40.7 (SD = 13.6) days. Neither CI nor HC differed by device type; however, the Fisher-Paykel device was associated with slightly greater HC growth rate. Conclusion CPAP devices and the pressures they apply plausibly contribute to preterm infant cranial molding over time, with the greatest potential impact on infants who require CPAP support for longer periods; however, these findings must be validated in larger cohorts. Additionally, positioning practices should be further examined to determine how they may contribute to or prevent the development of cranial molding deformity.
