A Preliminary Review of Infant Cranium Development During the First Six Months of Life

Infant cranial development undergoes rapid changes in the first six months, influenced by genetic and environmental factors. Understanding these patterns is crucial for distinguishing normal variation from pathological conditions. While research on cranial abnormalities is extensive, fewer studies focus on typical skull morphology. This review synthesizes existing literature on the three-dimensional (3D) evolution of the infant cranium, highlighting key growth patterns and methodological limitations. Using PubMed, studies employing advanced imaging techniques such as 3D stereophotogrammetry and computed tomography (CT) were assessed. Of 20 articles reviewed, only three met the criteria for healthy infant cranial development. Findings suggest a non-uniform growth pattern, with the most rapid changes occurring between three and six months. However, gaps in research persist due to small sample sizes, regional limitations, and a focus on pathology over normal variation. Establishing normative growth curves through larger, diverse cohorts is essential for improving clinical assessments, guiding early interventions, and refining computational models. This preliminary review underscores the need for a systematic study to enhance our understanding of early cranial development.
