    Trigeminal neuralgia (TGN) causes severe facial pain, with 44% of patients experiencing refractory pain despite medical treatment.

  • 2

    Motor cortex stimulation (MCS) has shown a median pain reduction of 70% in TGN patients unresponsive to other treatments.

  • 3

    Accurate positioning of the epidural electrode above the motor cortex is crucial for the success of MCS in treating refractory TGN.

  • 4

    Intraoperative electrophysiological monitoring and neuronavigation are employed to confirm the correct electrode placement during surgery.

  • 5

    General anesthesia is used to improve patient comfort while eliciting motor evoked potentials (MEPs) for electrode position verification.
