    Trigeminal neuralgia affects 3-14 individuals per 100,000 annually and is characterized by severe facial pain.

  • 2

    Radio-frequency thermal ablation (RFTA) is a preferred treatment for trigeminal neuralgia, especially after prior surgical interventions.

  • 3

    Triggered electromyography (T-EMG) enhances RFTA precision by allowing real-time trajectory adjustments under general anesthesia.

  • 4

    In a study of 27 RFTA procedures, 96% successfully encountered the foramen ovale using T-EMG, with no loss of mastication functionality.

  • 5

    Follow-up data showed 61.5% of patients experienced improvement in facial pain after RFTA, highlighting its effectiveness.
