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).

本研究对六十个秘鲁起源的干颅骨的轨道特性进行了量化分析。在眼眶区域及眼眶体积方面，双眼之间未见显著差异，然而左侧眼眶区域的内外壁测量值小于右侧。眼眶体积的测量结果与亚洲研究报道的数值相似，但与智利先前研究报道的结果有所不同。这一差异可由亚洲与美洲土著民族之间微小的遗传差异来解释，正如Cavalli-Sforza（1992）所证明的，而CANDELA研究小组发现，智利人的基因主要源自欧洲，类似于哥伦比亚人口（Ruiz-Linares A，2014）。
