Sex- and Age-Related Features of the Encephalometric Parameters of the Brain Hemispheres in Children of the Second Childhood Period.

We performed a retrospective analysis of the encephalometric parameters of the brain hemispheres in children aged 8 years (30 boys and 30 girls) and 11 years (30 boys and 30 girls). The variability of the parameters of the brain hemispheres depending on age and sex was studied. In 8-year-old children, sex differences were revealed in a significant number of basic parameters: the length of the right and left hemispheres and the lengths of the left frontal lobe, right parietal lobe, right and left occipital lobes. In 11-year-old children, the sex differences were revealed only in the width of the hemispheres. Interhemispheric asymmetry was found in 8-year-old children. The comparative analysis of the encephalometric parameters of the brain hemispheres in children during the second childhood period showed that the dynamics of their changes in this range is very insignificant.
