Localization of superior sagittal sinus before craniotomy is very crucial to prevent the complications of surgery. The goal of this study was to verify the anatomical relationship between the sagittal suture and the superior sagittal sinus (SSS).
Fifty adult cadavers were included in this descriptive analytic study. The length of sagittal suture and the width of sagittal suture and SSS were measured in three points: (bregma), (lambda) and midpoint of sagittal suture. Anatomical relationship between SSS and sagittal suture was analyzed.
Superior sagittal sinus was deviated to the right side of the sagittal suture in 54% of cases at bregma and 64% of cases at the midpoint of sagittal suture and lambda. SSS was located at the right side of sagittal suture about 3.5mm at bregma, 4.5mm at midpoint of sagittal suture and 5.7 mm at lambda. The right transverse sinus was dominant in 76% of cases. No gender-associated difference was noticed.
Our study demonstrates that SSS is deviated to the right side of sagittal suture in the majority of cases. Maximum deviation of SSS to the right side is about 10mm. Neurosurgeons are advised to be aware of this anatomical relation while operating around SSS.
开颅手术前对上矢状窦进行定位对于预防手术并发症至关重要。本研究的目的是验证矢状缝与上矢状窦（SSS）之间的解剖关系。
本描述性分析研究纳入了50具成年尸体。在三个点测量矢状缝的长度、矢状缝和上矢状窦的宽度：（前囟）、（枕外隆凸）和矢状缝中点。分析上矢状窦与矢状缝之间的解剖关系。
在前囟处，54%的病例中上矢状窦偏向矢状缝右侧，在矢状缝中点和枕外隆凸处，64%的病例如此。上矢状窦在前囟处位于矢状缝右侧约3.5mm处，在矢状缝中点处为4.5mm，在枕外隆凸处为5.7mm。76%的病例中右侧横窦占优势。未发现性别相关差异。
我们的研究表明，在大多数情况下，上矢状窦偏向矢状缝右侧。上矢状窦向右侧的最大偏移约为10mm。建议神经外科医生在围绕上矢状窦进行手术时了解这种解剖关系。
