Objective:To study the relationship between the jugular foramen and its adjacent structures,measure occipital condyle and paracondyle structures,to correctly direct operative approach.Methods:Observation and measurement of jugular formaen,occipital condyles,jugular process,hypoglossal canal and paracondylar tissues were carried out on 10 cadaveric head and 15 dry skull bases by using microsurgical anatomic skills. Results:Different ratio relations to atlantooccipital joint interfaces were decided for condylar...

Objective:To study the relationship between the jugular foramen and its adjacent structures,measure occipital condyle and paracondyle structures,to correctly direct operative approach.Methods:Observation and measurement of jugular formaen,occipital condyles,jugular process,hypoglossal canal and paracondylar tissues were carried out on 10 cadaveric head and 15 dry skull bases by using microsurgical anatomic skills. Results:Different ratio relations to atlantooccipital joint interfaces were decided for condylar extension drilled.Jugular process situated in the posteriolateral to condyle,interior to styloid and digastric groove,posterior to superiorlateral loop of vertebral artery, and consisted in posterior wall of jugular foramen.It companied with carotid canal and hypoglossal canal outside hole,and formed triangle that posterior groups nerve and jugular buld existed in.Conclusions: It′s advanced approach compard with suboccipital extreme approach.The exposure of jugular foramen posterior wall by drilling away partial condyle and jugular process,for avoiding facial nerve transposition and petrosal bone being drilled.

目的 :了解颈静脉孔区周围组织关系 ,量化枕髁及髁旁组织结构 ,为该手术入路提供解剖学基础。方法 :采用显微外科解剖学方法 ,对 10例成人尸体头部标本 ,15例干性颅骨标本 ,观测颈静脉孔、枕髁、颈突及舌下神经管等髁旁组织结构间关系。结果 :寰枕关节面不同的比例关系 ,决定枕髁的磨除范围。颈突位于枕髁的后外侧 ,茎突和二腹肌沟的内侧 ,后邻椎动脉上外侧袢 ,组成了颈静脉孔的后壁。与颈动脉管外口、舌下神经管外口形成了三角形 ,出颅的后组脑神经及颈静脉球位于三角形内。结论 :本入路是枕下外侧入路的改良 ,通过部分枕髁及颈突磨除 ,从后方显露颈静脉孔 ,避免了面神经移位及颞骨岩部的磨除。

Objective: To study the microsurgical anatomy of the jugular for amen region and to assess the usefulness of the TPA (transverse process of atlas ), rectus capitis laterralis muscle, jugular process and sulcus of the digastric muscle which are taken as reference guides in the exposure of the jugular foram en region. Methods: The microsurgical anatomy of the jugular foramen region and the relation to the TPA were investigated in fifteen cadaveric head-neck specime ns of adults. Results: Many of the important structures in this region can be id entified systematically. Laterally to the TPA sat the posterior belly of the dig astric muscle and the occipital artery. Posterior to the TPA, the suboccipital t riangle can be recognized. Within the triangle, the vertebral artery and its acc ompanying venous complex can be identified. The rectus capitis laterralis muscle extended vertically behind the internal jugular vein from the TPA to the jugula r process of the occipital bone. Anterior to the TPA, the styloid process could be exposed. The internal jugular vein and cranial nerve X, XI and XII sat betwee n the styloid process and the TPA. Conclusions: Surgeons can use the TPA, rectus capitis laterralis muscle, jugular process, sulcus of the digastric muscle as v ery useful landmarks in the jugular foramen region to help identify the importan t structures and to prevent unnecessary morbidity.

目的:研究颈静脉孔区的显微外科解剖,探讨寰椎横突(TPA)、头侧直肌、二腹肌沟、颈静脉突等解剖标志在颈静脉孔区病变手术中的定位意义。方法:成人头颈标本15例,男13例,女2例,红色乳胶灌注颈总动脉和椎动脉。手术显微镜下(×3~×30)逐层显露颈静脉孔区结构,明确该区显微解剖特征、相关的解剖标志及其定位意义。结果:颈静脉孔区多数重要的解剖结构均可以TPA为参照标志予以明确。二腹肌后腹位于其浅层。TPA的后方为枕下三角,三角内有椎动脉、椎静脉丛和颈1神经通过。头侧直肌起始于TPA的外表面,止于枕骨颈静脉突的下表面,可作为确定颅外颈静脉孔的解剖标志。茎突位于TPA的前方,颈内静脉、迷走神经、副神经、舌下神经穿行于茎突与TPA之间,颈内动脉位于颈内静脉的前内侧。二腹肌、颈静脉突、颈动脉嵴对定位面神经、颈静脉孔及舌咽神经等结构具有重要意义。结论:颈静脉孔区解剖结构复杂,利用寰椎横突、头侧直肌、二腹肌沟、颈静脉突等解剖标志有助于明确此区域重要的解剖结构,避免术中不必要的损伤。
