摘要
目的探讨改良眶颧-海绵窦入路增加基底动脉上段显露的方法。方法在10例标本上模拟了经眶颧-海绵窦入路,同时增加磨除前后床突,观察对基底动脉上段显露的改善情况。结果磨除前床突后形成的间隙为床突间隙,存在于颈内动脉与动眼神经间的膜为颈内动脉动眼神经膜。(沿此膜即可进入海绵窦,磨除后床突后,暴露鞍背、上斜坡,即可显露基底动脉上段)单纯眶颧入路显露基底动脉的长度(5.66±1.07mm),视角(前后方向48.6±5.1°,上下方向51.9±5.5°);附加磨除前后床突后显露基底动脉的长度(7.68±1.12mm),视角(前后方向56.5±5.7°,上下方向61.9±6.0°)。结论经眶颧-海绵窦入路中磨除前床突和后床突,可显著增加对基底动脉上段的显露。
Objective To explore the surgical techniques of exposure of the superior segment of basilar artery by using the improved orbitozygomatic-cavernous sinus approach. Methods The superior segment of basilar artery was exposed through the improved orbitozygomatic-cavernous sinus approach（stripping the anterior and posterior clinoid process） in 10 cadaveric heads. Results The clinoidal space（CS） was formed by stripping the anterior clinoid process. The film existed between the internal carotid artery （ICA）- oculomotor nerve （OMN） called ICA- OMN membrane. By only orbitozygomatic approach： the length of exposed basilar artery （5.66±1.07mm）, the visual angle （anterior-posterior 48. 6±5. 1°, up-down 51.9±5.5°）. After stripping the anterior and posterior clinoid process, the length of exposed basilar artery （7. 68±1.12 mm）, the visual angle （anterior--posterior 56.5±5.7°, up-down 61.9±6.0°）. Conclusion By stripping the anterior and posterior clinoid process through the orbitozygomatic- cavernous sinus approach, the superior segment of basilar artery can be exposed more.
