BACKGROUND For small and lateral lesions, in order to avoid postoperative sequelae related to dorso-median myelotomy, we propose to describe the use of a ventrolateral approach for intramedullary lesions. METHOD Performing this approach entails that the denticulate ligament is cut from its dural attachment and retracted. Rotation of the spinal cord must be achieved with great caution and under electrophysiological monitoring. After pia mater incision, hydrodissection is useful to gently dissect the cavernoma and promote a cleavage plane. CONCLUSION In the case of lateral intramedullary lesions, using this approach maximized the absence of postoperative deficit.

我该怎么做：腹外侧入路治疗腹侧髓内海绵状瘤。

背景技术对于小的和侧部病变，为了避免与背中正肌切开术相关的术后后遗症，我们建议描述使用腹侧入路治疗髓内病变。方法执行该方法需要将韧带韧带从其硬脑膜附件上切下并缩回。脊髓旋转必须非常谨慎并在电生理监测下进行。皮雅特切口后，水解剖可用于轻轻地解剖海绵瘤并促进卵裂平面。结论在外侧髓内病变的情况下，使用这种方法可以最大程度地减少术后缺损。
