Specific Morphometric Features of Superior Sagittal Sinus in Adults

Abstract

In order to determine the individual peculiarity of the shape, size, position and relations of the upper sagittal sinus, depending on the type of structure of the head in adults, craniometry and morphometry of the head sinuses were performed. The most significant venous collector of the brain is the upper sagittal sinus, which is located in the sagittal plane along the ridge of the lattice to the inner occipital projection. This formation is characterized by a triangular shape. The upper wall is formed by the leaves of the convex part of the solid membrane, and the two lateral walls by splitting the sickle of the cerebellum in the parasagittal plane. In adults, the upper wall contacts the inner surface of the parietal and occipital bones of the cranial vault. According to our data, the upper sagittal sinus has a specific range of variability depending on age, sex and head shape. The range of individual variability of the structure of the upper sagittal sinus was determined, which is characterized by the greatest values of length and height in adults, irrespective of gender with dolichomorphic head shape (narrow-headed) and increase in latitudinal parameters in people with meso- and brachymorphic head (middle and wide).
