MORPHOMETRIC STUDY OF ORBITARY AND PERIORBITARY REGION IN PERUVIAN SKULLS: IMPORTANCE TO SURGICAL APPROACH

This study quantifies the orbital characteristics of sixty dried skulls from Peruvian origin. There was no difference between both eyes in the periorbital region and orbital volume, however measurements of medial and lateral wall from the left orbital region are smaller than the right side. Orbital volumen measurements were similar to those reported by Asian studies but different from those reported by Chilean previous studies. It would be explained by the minimal genetic differences between Asian and Amerindian races, as demonstred by Cavalli-Sforza [1992], while CANDELA group found that Chilean genes are mostly of European ancestry, like Colombian population (Ruiz-Linares A, 2014).本研究对60例秘鲁来源的干燥颅骨的眼眶形态特征进行了量化分析。研究发现，双眼的眶周区域与眶容积均无显著差异，但左侧眼眶的内侧壁与外侧壁测量值均小于右侧。本次测得的眶容积与亚洲人群相关研究的报道结果相近，但与智利既往研究的结果存在差异。这一差异可通过亚洲人与美洲印第安人种之间极细微的遗传差异加以解释，该结论已由Cavalli-Sforza[1992]证实；而CANDELA研究团队发现，智利人群的基因大多源自欧洲祖先，与哥伦比亚人群相似（Ruiz-Linares A, 2014）。
