摘要
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 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.
