INDIVIDUAL PARAMETER DIFFERENCES SKULL AND LATERAL VENTRICLES WITH THE TYPES OF VENOUS-LIQUOR RELATIONSHIP IN PEOPLE OF MATURE AGE

Abstract

The results of a study aimed at determining the range of metric individual differences in the length, width, height parameters of the head (skull) and lateral ventricles in adults, as well as to carry out the craniometric analysis of the relationships between the venous and cerebrospinal fluid systems of the brain in adults of both sexes. The material of research was dura mater with its sinuses, ventricles of the brain and vault of the skull. We used a complex of macro – and microanatomy techniques. It has been shown that the longitudinal parameters of the head, cranial cavity and lateral ventricles usually prevail in male and female representatives with a dolichocephalic head shape (long-headed people). Respectively, certain craniotopographic relationships with the right and left lateral ventricles are formed. Craniometric correlations between the transverse dimensions of the studied objects of the cerebrospinal fluid system have been established. It has been found out that regardless of gender, there is a characteristic trend of gradual increase in the width of the head, skull cavity, and lateral ventricles from dolicho to meso- and brachycephals. The obtained craniometric data are important for purposeful and rational puncture of the lateral ventricles, which allow us to determine and take into account the distance of their location in relation to the bones of the skull vault. Two extreme types of relationships have been identified between venous-sinus formations of the dura mater of the cranial vault and cerebrospinal fluid-ventricular parts of the brain. The first is the loose type (scattered type), the second is the trunk type. In addition, there are a lot of intermediate forms of these relationships, differing in length and сoncentration of separate groups of venous tributaries along the superior sagittal and transverse sinuses.
