The morphometry and variations of confluence sinuum and related structures via the silicone painting technique on otopsy cases

The anatomic studies of the dural sinuses are seen rarely in the literature. In this study, we aimed to investigate the morphometric and morphological structures of the confluence sinuum and related structures with silicon painting technique.We studied 30 cadaver in this study. Twelve of them were washed with alchole and filled with silicone painting technique via VJI, ICA and VA. The rest 18 were cadaver cadavers. The CS and related structures were dissected under microscope, the normal anatomy were investigated and variations were noted. Diameter of the SSS, CS, OS, SR, bilateral TS and the angle between SSS-SR were measured.In this study, the mean diameters were SSS: 11,76 mm, CS:22,4 mm, OS: 5,29 mm, SR:7,53 mm, TS: (right: 9,73 and left: 9,13 mm) and angle between SR-SSS was 58 degree. There were no difference for the bilateral venous structures which drain to SSS and TS. There were extra drainage to the CS from the left side in 4 cases. The right TS were located superior in 7 cases compared with the left TS and this process related with the type of CS. Septum in the SSS was detected in 2 cases. Additionally, we encountered OS in the 80% of the cases.We have reported the angle between the SSS-SR and the effect of CS septum on the CS types and TS dominance. We also reported the superior location of TS and the effect of CS septum on it.
