Treatment Options For Trigeminal Neuralgia

Radiofrequency Thermal Lesioning

Radiofrequency thermal lesioning is a medical procedure in which specialized needles create lesions along specific nerves. The needles cause the nerve to reach a temperature of eighty degrees Celsius. The heat is applied for around two to three minutes, which deadens the nerve's ability to send pain signals. Though the body attempts to regrow blocked nerves, the process might take a year or longer. Some patients have seen a reduction in their symptoms for at least twelve months. Radiofrequency lesioning is usually used in trigeminal neuralgia and other conditions caused by nerve pain from the facial nerves. Before a patient can undergo a lesioning treatment, they must have shown good responses to local anesthetic blocks previously. Radiofrequency thermal lesioning is much more effective in those who have responded well to having their nerves temporarily blocked. About seventy to eighty percent of patients report their nerve is blocked well enough to relieve some pain. In some cases, blocking the nerve will help isolate pain caused by other nerves as well.
