ABSTRACT
Background: Dural venous sinuses need further attention either for its anatomical structure or relationship to its neighborhood neurovascular formations in and around the temporal bone. In this study, the widths of the sigmoid sinus-jugular vein complex are measured in five different levels. The distances between this complex two some of the important temporal bone landmarks are also evaluated. Materials and Methods: Eight adult male cadavers (6 right, 8 left side) fixed with formaldehyde were used in this study. Mastoidectomy was performed under a surgical microscope (Zeiss Opmi 99, Germany). The distances between the Henle spine to the middle fossa dura, the sigmoid sinus to the facial nerve, the jugular bulb to the second genus of facial nerve and the crista fenestrae cochlea were measured. Received total 5 levels of cross-sectional areas were calculated that were established at five different levels of sigmoid sinus-jugular vein complex by point counting method. The differences between levels and the sides were evaluated with the Wilcoxon signed-rank test. The relationship amoung the about mention factors was evaluated with Spearman's correlation test. Results: Differences between levels and correlation characteristics have been introduced in tabular form. Correlation between the levels was found only on the left side. Regarding the landmarks of the temporal bone, positive correlation was found between the cross-sectional area of the jugular bulb with the 'distance between the Henle spine to the middle fossa dura' and negative correlation was found between the `distance of the jugular bulb to the crista fenestrae cochlea. Conclusion: Important correlations were found between the anatomical structure and the dimensions of the sinus-vein complex to the important landmarks of the temporal bone affecting the appropriate surgical approach to this area.
