Abstract
High success rates of radiofrequency lesioning in patients with refractory trigeminal neuralgia. A side effect which is often seen after radiofrequency lesioning is a mild burning sensation in the treated dermatome, which subsides spontaneously after some weeks. Limited evidence about the clinical effectiveness of radiofrequency lesioning for spinal pain: with better evidence for percutaneous facet denervation than for the treatment adjacent to the dorsal root ganglion and heating of the intervertebral disk. In patients with chronic nonmalignant pain, radiofrequency lesioning should be imbedded in a biopsychosocial setting. In Radiofrequency (RF) lesioning, heat is generated in the tissue which surrounds the electrode by the RF current generated by a lesion apparatus. The RF voltage from the generator is set up between the electrode and the groundplate, which is placed on the arm or leg of the patient. The rationale for the application of RF denervation is the assumption that selectively heating nervous structures can impede nociceptive input.
