A preliminary study on the relationship between the complexity of the sagittal suture and cranial dimensions

The paper presents the results obtained from analysis of the correlation between cranial dimensions (length, width, and height) and indices against the complexity of the sagittal suture, which was expressed as the ratio between absolute sutural length to the linear length of the suture. The statistical study on 29 skulls shows a significant negative correlation between the height/width index of all skulls and suture complexity (r = –0.78 for male, r = –0.70 for female skulls) and a negative correlation between cranial height and suture complexity in male skulls only (r = –0.49). This implies that lower and broader skulls have a more complicated sagittal suture. Correlations of the height/length and width/ /length ratios were assessed as statistically insignificant in both sexes.
