Study on the growth of intracranial volumes in normal children of different ages / 中华整形外科杂志

ABSTRACT

Objective@#The purpose of this study was to measure intracranial volumes in normal children of different ages and to explore the growth of intracranial volumes.@*Methods@#A total of 151 normal children (male, 96; female, 55) were included in this study who were subjected to computed tomography (CT) for head trauma in the pediatric emergency room from June 1, 2015 to July 31, 2015. All of them had no congenital deformities and depressed fracture of the skull. Total, anterior, middle and posterior intracranial volumes were measured using a DICOM viewer. The Graphad Prism 6.0 was applied to analyze the data and plot the best fit logarithmic growth curve and liner regression and the comparison of the growth curves between different groups was done.@*Results@#The intracranial volumes had a rapid growth within 2 years old. The girls′ total intracranial volumes were smaller than the boys′ of the same age. There was a significant difference of linear regression slope between anterior intracranial volumes and posterior intracranial volumes within 2 years old (P<0.01).@*Conclusions@#There is a rapid growth of intracranial volumes of normal children within 2 years old. The posterior intracranial volumes are expanded faster than the anterior intracranial volumes in the first two years. The girls′ intracranial volumes are smaller than the boys′.
