Objective: The drainage of the dural vein sinuses, and therefore, the traces caused on the bone are highly variable. Knowing the transvers sinus variations and related morphometric features is extremely important in surgical interventions in the area. The purpose of the present study was to determine the variations of sulcus of the transvers sinus and its relations with adjacent structures. Methods: In the present study, 34 skulls of unknown gender and age of Çukurova University, Faculty of Medicine, Department of Anatomy were used. After the types of sulcus of the transvers sinus (ST), the distance of the uppermost (STU) and lowestmost (STA) point of the sulcus of the transvers sinus on the right and left to the foramen magnum (FM), the superior nuchal line (LNS) of the foramen magnum were identified, the distance between inferior nuchal line (LNI) and superior nuchal line-inferior nuchal line was measured by using digital caliper nearest 0.1 mm. The SPSS Statistics 20 program was used for statistical analyses, and descriptive statistical methods were used in the evaluation of the data. Categorical measurements are summarized as numbers and percentages, and continuous measurements as mean and standard deviation. The conformity of the variables to the normal distribution was evaluated with the Shapiro Wilks Test, and the comparisons were made with the Paired Samples t-Test. Results: Transvers sinus types was detected by 61.77% as bifurcate type, 17.64% as confluens type, 11.77% as left dominant type, and 8.82% as right dominant type. The following measurements were made; STU(right)-FM 51.08±4.92 mm; STU (left)-FM 49.35±4.54 mm; STA (right)-FM 37.93±4.14 mm, STA (left)-FM 37.22±4.33 mm; FM-LNS 41.92±5.3 mm; FM-LNI 22.10±3.93 mm; LNS-LNI was measured as 21.28± 3.74 mm. No significant differences were detected between right and left side measurements (p>0.05). Conclusion: It is considered that identifying the variations and localization of the transvers sinus will contribute to the prevention of undesirable outcomes such as bleeding and thrombosis and to increase the surgical success in interventions such as the infratentorial supracerebellar approach to the skull.
