Microvascular conflicts in hemifacial spasm typically occur at the facial nerve's root exit zone. While a pure microsurgical approach offers only limited orientation, added endoscopy enhances visibility of the relevant structures without the necessity of cerebellar retraction.
After a retrosigmoid craniotomy, a microsurgical decompression of the facial nerve is performed with a Teflon bridge. Endoscopic inspection prior and after decompression facilitates optimal Teflon bridge positioning.
Endoscope-assisted microsurgery allows a clear visualization and safe manipulation on the facial nerve at its root exit zone.
面肌痉挛的微血管冲突通常发生在面神经神经根出口区。单纯的显微外科方法提供的定位有限，而内镜的加入可以增强相关结构的可视性，而无需小脑牵拉。
在乙状窦后颅切开术后，通过特氟隆桥对面神经进行显微减压。减压前后的内镜检查有助于特氟隆桥的最佳定位。
内镜辅助显微外科可以清楚地观察面神经神经根出口区的面神经，并进行安全操作。
