One of the complex sections of modern neuromorphology is the cerebrospinal fluid system, which has a considerable range of age, sex, and individual features of shape, size, and position in people with different head and skull structures. The cerebrospinal fluid system has continued to be the subject of scientific research in clinical anatomy and neurosurgery, especially since the end of the last century in connection with the emergence of new research methods: radiography, computed tomography and magnetic resonance imaging (CT and MRI). This greatly complements our understanding of the structures under study, especially in diagnostic and treatment. In this regard, the lateral ventricles perform the most important function in regulating cerebral efflux and normalizing intracranial pressure. They are the major reservoirs that accumulate tissue fluid in the cerebral hemispheres. The purpose of the study is to study the craniotopographic features of the structures of the lateral ventricles and their parts depending on the age, gender and individual shape of the head. The study was performed on 40 native brain preparations with meninges of adult age people, obtained during forensic dissections of corpses. At the same time, anthropo- and craniometric measurements of the head, skull were performed, and a main index was established between the sizes of generally established craniometric points. Determined the length of the head above the bridge of the nose (glabella); external occipital protuberance (opistocranion); head width – between the farthest points of the parietal bones (eurion). The brachi-, meso- and dolichocephalic were separated in relation to the main index indicators. In addition, corrosion (acrylate) models of lateral ventricles and their compartments were made on 10 native preparations, using ACR-7, ACR-14 or noracryl. A series of lateral ventricular morphometry was performed with the help of a set of measuring instruments and developed devices and compared with the parameters on the craniogram. The lateral ventricles are characterized by a complex anatomical shape, which is represented by a double configuration of tubular structures in each hemisphere of the brain. It is known that the lateral ventricles consist of four compartments. The lateral ventricles have been found to have a natural range of variability in linear dimensions characteristic of adult age males and females. According to our data, the length of the anterior horns of the lateral ventricle in adult males ranges from 2.65 to 3.5 cm; in females – from 2.65 to 2.85 cm. The width of the initial compartment or base of the anterior horns varies from 1.6 to 2.7 cm (males), and from 1.5 to 2.2 cm (females). The width of the final section or tip of the horns does not exceed 0.5 – 0.9 cm, regardless of gender. It is established that the total length of the central part of the lateral ventricle in adult males ranges from 3.8 to 4.3 cm, in females – from 3.7 to 4.1 cm. The range of gender differences of this parameter is small and is equal to 0.4 – 0,5 cm. The craniotopographic features of the linear parameters of lateral ventricles and their parts in adult age with predominance of the indicators in the males have been established. Further investigation is planned to study the individual anatomical variability of the shape, size, position and relationship of lateral ventricles with closely located structures of the cerebral hemispheres.
