| 摘 要： | 目的 为内镜下远外侧枕髁后锁孔入路治疗岩下斜区及周围疾患提供解剖学基础。 方法 10具尸体头标本于乳突后作纵向“S"型、约7 cm长头皮切口,上缘起自乳突中点向后2 cm处,下界至C2水平。做直径约2 cm的骨窗,牵开小脑半球,内镜下观察所显露的解剖结构。 结果 内镜下可以观察到后组脑神经的出颅部位,包括颈静脉孔和舌下神经管内口,此外,还可以显露脑干腹侧面的结构及椎动脉的末端。神经与血管间复杂毗邻关系亦可得以显示;骨窗外缘至颈静脉内口的距离为(1.75±0.29) cm。 结论 内镜的使用,可缩小远外侧枕髁后锁孔入路的骨窗;副神经的脊髓根及颈静脉孔内口均可以作为经远外侧枕髁后锁孔入路内镜下岩下斜区结构的定位标识。

| Abstract: | Objective To explore the endoscopic anatomical characteristics of the inferior petroclival region and the clinical feasibility of the retro-condylar keyhole approach to the region.Methods Ten adult cadaver heads were used in this study.A longitudinal S shape skin incision about 7 cm was performed with its super border 2 cm behind the middle point of mastoid and inferior margin at the level of C2.A bone flap(2 cm in diameter) was cut with a craniotome and the cerebellar hemisphere was retracted.The exposed a... |
