Background

Microvascular decompression (MVD) for glossopharyngeal neuralgia (GPN) is associated with high complication and incomplete cure rates because of its poor ability to visualize neurovascular conflicts.

Method

Fully endoscopic MVD for GPN was carried out through a retrosigmoid keyhole approach. Neurovascular conflicts were clearly demonstrated with a loop of the posterior inferior cerebellar artery (PICA) under a 30° endoscopic view, and no significant cerebellar retraction was observed. The loop of the PICA was safely decompressed and the perforators were preserved while offering an excellent operative view.

Conclusion

Endoscopic MVD is a reliable and minimally invasive method for GPN.

我该怎么做：内镜微血管减压治疗舌咽神经痛。

背景

舌咽神经痛（GPN）的微血管减压术（MVD）与高并发症和不完全治愈率相关，因为其可视化神经血管冲突的能力较弱。

方法

GPN的全内镜MVD是通过乙状结肠后锁孔入路进行的。在30°内窥镜检查下，小脑后下动脉（PICA）环清楚地显示出神经血管冲突，并且未观察到小脑明显回缩。对PICA的回路进行了安全的减压，并保留了穿孔器，同时提供了出色的手术视野。

结论

内窥镜MVD是一种可靠且微创的GPN方法。
