摘要
目的 :进一步明确颈静脉孔区的断面形态和各结构的解剖关系 ,为影像诊断和手术治疗提供解剖学依据。方法 :成人尸体头颈部标本 7例 ,制成 0 .5～ 1.0mm厚的水平位和冠状位火棉胶切片。结果 :①颈静脉孔入口处分舌咽道和迷走道两部分 ,但颈静脉孔腔内未见骨桥或纤维桥将其分部。②岩下窦最多见于注入颈静脉球的下部。③髁导静脉多汇入乙状窦与颈内静脉移行处。④舌下神经管静脉丛充满舌下神经管 ,出管后与岩下窦汇合注入颈静脉球或颈内静脉。舌下神经沿舌下神经管的前下壁走行。⑤颈静脉球与面神经垂直段关系密切。结论 :火棉胶薄切片很好地显示了颈静脉孔区的正常解剖结构及其毗邻关系 ,对该区的影像诊断和手术治疗有重要的参考价值。
Objective: To provide the sectional anatomic data of the jugular foramen for imaging diagnosis and surgery. Methods: Seven adult cephalic specimens were sliced into 0.5～1.0 mm celloidin contiguous sections on transverse and coronal plane. Results: 1. At the intracranial portal of the foramen, the dura formed two perforations. However, there was no bony bridge or fibrous compartmentalization within the foramen. 2. The inferior petrosal sinus commonly drained into the jugular bulb. 3. The condylar emissary vein chiefly joined the connection of the internal jugular vein and the sigmoid sinus. 4. The venous plexus filling of the hypoglossal canal joined the inferior petrosal sinus and then terminated in the jugular bulb or the internal jugular vein. The hypoglossal nerve was located anteroinferiorly within the canal. 5. There was intimate anatomic correlation between the perpendicular segment of facial nerve and the jugular bulb. Conclusion: The thin sections of celloidin clearly delineated the anatomic details of the jugular foramen and their relationship, and provide valuable information to imaging diagnosis and surgery of this area.
