Abstract

Background: The skull of newborn normally consists of seven bones: the paired frontal, temporal, and parietal bones, and the single occipital bone, and six sutures including the paired coronal and lambdoid sutures, and the single sagittal and metopic sutures. The anatomical knowledge of the pediatric skull is a challenging task, and the stages of its development are not easily recalled by radiologists. Materials and Methods: The sagittal suture and bilateral coronal sutures were evaluated for 483 patients, ages 1 day to 395 days collected retrospectively from electronic medical records. Histograms as well as normality and boxplots were used to view the distribution of the data. Results: The average proximal suture widths for the sagittal and coronal sutures at zero months of age were 4.9 ± 0.13 and 2.45 ± 0.13 mm, respectively. From zero to 1 month of age, these sutures narrowed significantly to 2.3 ± 0.15 and 1.3 ± 0.13 mm, respectively. From 1 to 12 months of age, sutures narrowed gradually. The proximal coronal suture widths showed a significant reduction from 1 month to 12 months (1.3 ± 0.13 to 0.85 ± 0.12 mm). Conclusions: This study provides normal reference values for suture widths established by CT scan among a sample of Indian infant population and it may be used to assess the infant calvaria for suture diastasis.
