Lesen Sie diesen Artikel auf Deutsch.


  • Percutaneous radiofrequency thermocoagulation (RFT) to reduce pain in people with idiopathic trigeminal neuralgia (ITN) is more successful in those with provoked episodic pain, mixed pain, and no history of surgical treatment.

Why this matters

  • ITN is a chronic pain syndrome with high incidence especially in the elderly; while drugs are the first strategy, they often have side effects or are not effective.

  • RFT is a minimally invasive option and identifying patients more likely to have successful outcomes and risk factors of unsuccessful results will aid in treatment choice.
