The sphenoidal canal is described in perinatal material, and was found in 57 out of 58 disarticulated human skeletal remains collected in Egypt between 1918 and 1928. The canal showed considerable variations in extent and morphology, but ran essentially from the region of the developing rostrum of the sphenoid in an anterosuperior direction to end in the tuberculum sellae, immediately behind the optic groove. The canal represents the impression left by the remnants of the sphenoidal synchondrosis between the presphenoid and postsphenoid. The arrangement suggests that as a growth area this synchondrosis is of limited importance once the perinatal period is reached. The spatial relationship between craniopharyngeal and sphenoidal canals is described.
蝶管在围产期材料中有描述，在1918年至1928年间于埃及收集的58具分离的人类骨骼遗骸中有57具发现了蝶管。该管道在范围和形态上有相当大的变异，但基本上从蝶骨发育中的吻突区域向前上方延伸，止于视沟后方的鞍结节。该管道代表蝶骨前体与蝶骨后体之间蝶骨软骨结合残余留下的痕迹。这种排列表明，一旦进入围产期，作为一个生长区域，这种软骨结合的重要性有限。本文描述了颅咽管与蝶管之间的空间关系。
