摘要
在325只成人干颅骨上对颈静脉孔骨桥进行了观察,仔细解剖观察了65具(130例)成人尸体颅骨颈静脉孔中血管—神经的毗邻关系。颈静脉孔骨桥可分2型:I 型:骨桥由颞骨颈静脉孔内棘与位于舌下神经管上方的枕骨颈静脉孔内突相接而成, 占21.5%。Ⅱ 型:骨桥由颞骨颈静脉孔内棘与位于舌下神经管后方的枕骨颈静脉内孔突相连而成,占3.7%。对颈静脉孔有关结构的临床意义进行了讨论。
The anatomical nature and pattern of incident of bony bridging of thejujular foramen was investigated using 325 adult skulls.In addition,the regionof the jugular foramen on 65 adult cadavers was carefully dissected in orderto clarify the nerve-vessel relations in the jugular foramen region.The bonybridging of the jugular foramen may occur in one of two forms.Type I bridgingof the jugular foramen,established by the contact of the intrajugular spine of thetemporal bone with the bony process of the occipital bone projecting from abovethe hypoglossal canal,is present in 21.5%.Type Ⅱ bridging of the jugular fora-men,formed by the contact of the intrajugular spine of the temporal bone withthe bony process of the occipital bone projecting from posterior to the hypoglossalcanal,is present in 3.7% of the specimens.
