The sphenoidal bones of 70 adults were removed at post-mortem and were examined for the degree of pneumatization, number of intersphenoidal septa and the relationship of the septa to the lowest portion of the sellar floor. In 85.7%, pneumatization was of the sellar type, in 11.4% of the pre-sellar type and in 2.8% of the conchal type, as defined here. A single septum was present in 61%, two septa in 14%, more than two septa in 12.8% and no septum was present in 11.4%. The insertion of the septum represented the lowest point in the sellar floor in 50% of the bones. In these the septum was located in the center of the sellar floor. Attachment to one or the other side did not correspond to the lowest point of the sellar floor.
对70具成年尸体的蝶骨进行了尸检后移除，并检查了气化程度、蝶骨间隔数量以及间隔与鞍底最低部分的关系。按照此处定义，85.7%为鞍型气化，11.4%为鞍前型气化，2.8%为鼻甲型气化。61%有单个间隔，14%有两个间隔，12.8%有两个以上间隔，11.4%没有间隔。50%的蝶骨中，间隔的附着点代表鞍底的最低点。在这些蝶骨中，间隔位于鞍底中央。附着于一侧或另一侧并不对应于鞍底的最低点。
