上矢状窦(SSS)、直窦(SS)、枕窦(OS)和两个横窦(TS)的交界处代表鼻窦汇合处(CS；扭转鼻窦)。这项研究的目的是通过对鼻窦的形态观察来解释CS周围的鼻窦血流。本研究基于对31具成人身体的CS区硬脑膜静脉窦的目视检查。在流入区，我们考察了SSS和SS的流动方向。在通信区，我们检查了流出的鼻窦与其他鼻窦的交流程度。在流出区，我们使用流出窦的直径来确定解剖优势。经右侧TS入CS 16例(51.6%)，经CS中心入CS 14例(45.2%)。SS经CS中央进入18例(58.1%)，经左侧TS进入11例(35.5%)。流出窦通畅26例(83.8%)，部分通畅5例(16.2%)。部分沟通是分隔性CS的结果。在流出方面，右侧TS占优势11例(35.5%)，对称性18例(58.1%)。SSS流入方向与SS流入方向不同，5例(16.1%)可见部分交通。因此，鼻中隔的存在可以被认为是一个解剖学因素，对CS的诊断或牺牲流出性窦具有一定的意义。克莱恩。阿纳特。21：294-300,2008。©2008 Wiley-Liss，Inc.
The confluence of sinuses (CS; torcular herophili) is represented by the junction of the superior sagittal (SSS), straight (SS), occipital (OS), and two transverse sinuses (TS). The objective of this study was to interpret sinus flow around the CS by morphological investigation of the sinuses. This study is based on visual examination of dural venous sinuses in the region of the CS in 31 adult cadavers. In the inflow zone, we examined the direction of SSS and SS flow. In the communication zone, we examined the extent to which outflow sinuses communicate with other sinuses. In the outflow zone, we used the diameters of outflow sinuses to determine anatomical dominance. The SSS entered the CS via the right TS in 16 cases (51.6%) and via the center of the CS in 14 cases (45.2%). The SS entered via the center of the CS in 18 cases (58.1%) and via the left TS in 11 cases (35.5%). Outflow sinuses communicated freely in 26 cases (83.8%) and communicated partially in five cases (16.2%). Partial communication was the result of a septate CS. In terms of outflow, the right TS was dominant in 11 cases (35.5%), and in 18 cases (58.1%), outflow was symmetrical. The direction of SSS inflow was different from that of SS inflow, and partial communication was observed in five cases (16.1%). Therefore, the presence of a septum may be considered an anatomical factor, with implications in diagnosis or in the sacrifice of the outflow sinus of the CS. Clin.
