Malakhov S. Features of innervation of the tentorium cerebelli and its derivatives of venous formations in middle-aged people

The dissertation presents theoretical substantiation and a new solution to the problem of considering and understanding the features of innervation of the tentorium cerebelli and its derivatives of venous formations in people of mature age, depending on the structure of the human head. Established the existing range of individual anatomical variability of the shape, size and position of the tentorial branches in different parts of tentorium cerebelli in middle-aged people of male and female subjects. In this case, morphometric parameters of the relationship between tentorial nerve and tentorium cerebelli and falx cerebelli leaves in people with extreme forms of the structure of the head (brachi, meso- and dolichocephals) were revealed. The peculiarities of innervation of venous sinuses of the dura mater of the brain, which are formed by tentorium cerebelli and falx cerebelli leaves, have been studied in detail. Along with this, it is established that there is an individual anatomical variability of the correlation of the thickness of the walls of the sinuses of the dura mater of the brain and the diameter of the nerve endings of the tentorial nerves. For the first time histological computational diagrams of location and branching of the left and right tentorial nerve from the standpoint of the teaching of individual anatomical variability of the structure and form of tentorium cerebelli and surrounding troughs of the dura mater of the brain are made. In this case, the morphometric relationships between the different parts of the process and the nervous structures of the tentorial nerve along its trunk, the main, intermediate and terminal branches are established. The established results of the study should be taken into account when performing neurosurgical surgical interventions. The specified characteristics of the layers of the structure of the tentorium cerebelli and the surrounding sinuses of the dura mater of the brain with the establishment of an existing range of variability in the thickness of their leaves and walls, as well as the localization of tentorial nerve and his structures, is important, as it is important for performing surgical access with the performance of tentoriotomy. The peculiarities of localization, branching and relations of the nerve branches of tentorial nerve are determined, which is important for proper understanding of the origin of headaches in the area of the posterior cranial fossa with lesions of the first branch of the trigeminal nerve.
