Efficacy and Safety of Computed Tomography-Guided Percutaneous Balloon Compression under Local Anesthesia for Recurrent Trigeminal Neuralgia: A Prospective Study

Figure 2

If the foramen ovale is small, it will cause difficulty in piercing. Ct-guided needle puncture significantly improved the accuracy. The injection of anesthetics into Meckel’s cavity should be avoided during local anesthesia, and the 3D digital imaging technology can clarify the tip location and improve the safety.
