Scaphocephaly is caused by premature sagittal suture closure. It restricts medial-lateral growth of the cranial vault which appears longer and narrower than normal. We examined how this natural malformation affected morphology of the cranial base and face. A prehistoric adult male Hopi with scaphocephaly was compared to 19 normal male Hopi (Old Walpi Series, Field Museum of Natural History, Chicago, IL). Three-dimensional coordinates of 53 landmarks were recorded on the cranial vault, cranial base, and face. Finite element scaling analysis was used to test for significant differences between the scaphocephalic and normal individuals in craniofacial morphology. Finite element scaling results indicated that scaphocephaly has a profound effect on cranial vault morphology. However, morphology of the cranial base and face were only slightly affected and, typically, are within the normal range of variation for the sample. An abnormality in the cranial base is not associated with scaphocephaly in this individual.
舟状头畸形是由矢状缝过早闭合引起的。它限制了颅顶的左右生长，使颅顶看起来比正常情况更长更窄。我们研究了这种自然畸形如何影响颅底和面部的形态。将一名患有舟状头畸形的史前成年男性霍皮人与19名正常男性霍皮人（老瓦尔皮系列，芝加哥菲尔德自然历史博物馆，伊利诺伊州）进行了比较。在颅顶、颅底和面部记录了53个地标点的三维坐标。使用有限元缩放分析来测试舟状头畸形个体与正常个体在颅面形态上的显著差异。有限元缩放结果表明，舟状头畸形对颅顶形态有深远影响。然而，颅底和面部的形态仅受到轻微影响，通常在样本的正常变异范围内。在这个个体中，颅底异常与舟状头畸形无关。
