Could craniometric measurements explain the growth of the superior sagittal sinus?

OBJECTIVE: The objective of this study was to relate demographic variables and craniometric measures with measurements of the superior sagittal sinus (SSS) at different points along the path of the SSS. The findings were then discussed with regards to theories of skull growth. METHODS: We studied 33 skulls with known demographic characteristics and measured various craniometric parameters and distances related to the specific dimensions of the SSS. These data were statistically analyzed, and the results are presented. RESULTS: Of the 33 cadaver samples, 16 were female and 17 were male, aged between 28 and 87 years at the time of death. The cross-sectional area of the SSS measured at the coronary suture was positively correlated with the biauricular length. In addition, when measured 1.5 cm above the torcula, the cross-sectional area of the SSS was negatively correlated with the distance between the medial epicanthi. CONCLUSIONS: The relationships found may indicate that the growth of the SSS is proportional to the activity of each segment of the SSS that occurs along its path.
