Technique of Awake Computed Tomography-guided Percutaneous Balloon Compression of the Gasserian Ganglion for Trigeminal Neuralgia.

The classic percutaneous balloon compression (PBC) technique is used to complete an operation under the guidance of C-arm radiography under general anesthesia, making communication with patients during the operation impossible. It is not accurate or objective to predict the classic technique's curative effect solely by determining whether the projection of the x-ray lateral image of the filled balloon is pear-shaped.
