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 jugular ostium bridge was observed on 325 adult skulls and the vascular-nerve neighbors in the jugular foramen of 65 adult (130) adult cadaver eyes were carefully dissected. Jugular foramen can be divided into two types: I type: Bone bridge by the temporal bone jugular foramen and located in the sublingual nerve canal above the occipital jugular foramen were connected, accounting for 21.5%. Ⅱ type: bone bridge by the temporal bone jugular foramen spinosum and suboccipital nerve canal in the back of the occipital jugular vein connected together, accounting for 3.7%. The clinical significance of the structure of the jugular foramen was discussed.
