摘要
目的探讨经颈前外侧入路及其扩大入路手术治疗斜坡及上颈椎腹侧病变的方法。方法在经10%甲醛溶液固定的尸头标本上,模拟颈前外侧入路及其扩大入路进行斜坡和上颈椎腹侧的显微解剖和手术入路研究。结果颈部前外侧有明确的筋膜间隙,通过对颈筋膜各层准确的广泛解剖可直达斜坡中上部和上颈椎腹侧;各筋膜层及骨性结构表面均有明显的解剖学标志。外侧入路可安全暴露下斜坡和上颈椎腹侧区域,其扩大入路可充分显露中上斜坡腹侧。结论经颈前外侧入路及其扩大入路手术治疗斜坡及上颈椎腹侧病变具有直达病变部位,损伤小,视野较宽和有效避免感染等优点。
Objective To explore the surgical treatment for the ventral lesion of clivus and upper cervical vertebra by anterolateral cervical approach and its extended approach. Methods Adult formalin-fixed cadaver heads were researched for microanatomical and surgical approaches to the ventral clivus and upper cervical vertebra through mimicing the anterolateral cervical approach and its extended approach. Results There were clear fascial spaces in the anterolateral neck. The wide and accurate dissection of the cervical fascial planes could directly access the ventral upper clivus and cervical vertebrae. There are anatomical landmarks on the surface of each fascial plane and bony structures. The ventral part of the lower clivus and upper cervical vertebra can be safely exposed via anterolateral cervical approach, and the ventral part of the upper clivus can be exposed via extended approach. Conclusion Anterolateral cervical approach and its extended approach for ventral lesion of elivus and upper cervical vertebra can reach the lesion directly, with a wider operating field and less damage, and avoid the infection effectively.
