Sagittal suture as an external landmark for the superior sagittal sinus

Restricted access

Object. Historically, the sagittal suture has been used as an external landmark to indicate the middle portion of the superior sagittal sinus (SSS). The goal of this study was to verify this relationship.

Methods. The authors examined 30 adult cadavers to reveal the location of the SSS with respect to the sagittal suture. Their findings demonstrated that the SSS is deviated to the right of the sagittal suture in the majority of observed specimens, although the maximum displacement to the right side was never more than 11 mm.

Conclusions. This information should be useful to the neurosurgeon who must be aware of the SSS and its relationship with superficial skull landmarks.
