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.
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.
Endoscopic MVD is a reliable and minimally invasive method for GPN.
由于可视化神经血管冲突的能力较差，舌咽神经痛（GPN）的微血管减压术（MVD）并发症发生率高且治愈率低。
通过乙状窦后锁孔入路对GPN进行全内镜下MVD。在30°内镜视野下，小脑后下动脉（PICA）袢清晰显示神经血管冲突，未观察到明显的小脑牵拉。PICA袢得到安全减压，保留穿支血管，同时提供了极佳的手术视野。
内镜下MVD是治疗GPN的一种可靠且微创的方法。
