Abstract：
Endoscopic microvascular decompression (eMVD) provides excellent visualization and minimally invasive surgical treatment of trigeminal neuralgia (TN). The transposition technique is desirable for long-term outcomes of TN.
A two-step transposition technique is performed during eMVD for TN due to the arch-shaped superior cerebellar artery (SCA). First, the cerebellomesencephalic segment of the SCA is pulled out using oxycellulose balls. Second, the retracted lateral pontomesencephalic segment of the SCA is detached from the trigeminal nerve and is transposed for fixation at the tentorium cerebelli.
The two-step transposition technique offers simple, reliable decompression for TN due to the arch-shaped SCA.

摘要：
内镜微血管减压术（eMVD）为三叉神经痛（TN）提供了出色的可视化和微创手术治疗。转座技术对于TN的长期结果是理想的。
由于弓形小脑上动脉（SCA），在TN的eMVD过程中进行了两步转位技术。首先,使用氧化纤维素球拔出SCA的小脑中脑段。第二,SCA的缩回的外侧桥脑段与三叉神经分离，并转置以固定在小脑幕上。
两步换位技术提供了简单的，由于拱形SCA，TN的可靠减压。
