Abstract

Trigeminal neuralgia (TN) is one of the most common causes of facial pain. Sometimes medical treatment is not effective enough and may have unacceptable side effects. Other treatment options include surgical interventions and minimally invasive techniques such as percutaneous rhizotomy with glycerol, percutaneous balloon decompression, and percutaneous radiofrequency thermocoagulation (CRF). CRF is widely used for TN treatment, but high temperatures >70 °C can cause serious complications, while lower temperatures are inefficient. Pulsed radiofrequency (PRF) uses the current in short, high-power pulses, while the ‘silent’ phase allows heat elimination and temperature of the tissue generally does not exceed 42 °C. The mechanism by which PRF leads to pain reduction without thermal damage to the tissue is not fully understood, but rapid changes in the electrical fi eld are assumed to result in altered transmission of pain signals. According to available literature, compared to CRF, effi cacy is lower, but with signifi cantly less complications. However, the prolongation of PRF time from 2 to 6 to 8 minutes can signifi cantly increase the effi ciency of this method.
