The metopic suture of 24 adult skulls investigated showed recognisable varied morphological patterns. The metopic suture resembled wavy lines and was sometimes highly convoluted, especially in the superior part of the frontal bone. The mean suture length was computed as 123.1 mm (SD = 5.307) and the mean fractal dimension was 1.17 (SD = 0.076). Visual inspection of the morphological character of the metopic sutures revealed complex variation in their course between the nasion and the bregma. Comparison of the fractal dimensions indicated a two-fold increase in complexity between the anterior half of the suture terminating in the nasion (FD = 1.10) and the second half of the suture beginning in the bregma (FD = 1.21). The Mann-Whitney test confirmed the statistical significance of the differences in the fractal dimensions calculated. The variety and complexity of the interdigitations in the anterior and posterior part of the suture point to possible alterations to local strains, which occur during the growth of the braincase.
对24个成人颅骨的额缝进行研究，发现其形态模式多样且可识别。额缝形似波浪线，有时高度卷曲，尤其是在额骨上部。平均缝长计算为123.1毫米（标准差=5.307），平均分形维数为1.17（标准差=0.076）。对额缝形态特征的目视检查显示，在鼻根点和前囟之间，其走行存在复杂变化。分形维数的比较表明，终止于鼻根点的缝前半段（分形维数=1.10）和始于前囟的缝后半段（分形维数=1.21）之间的复杂性增加了两倍。曼-惠特尼检验证实了所计算的分形维数差异具有统计学意义。缝前后部分交错的多样性和复杂性表明，在脑壳生长过程中，局部应变可能发生改变。
