Radiofrequency Thermal Lesioning
Radiofrequency thermal lesioning is a method that eliminates nerve fibers related to pain. Firstly, the doctor needs to sedate you before inserting a needle through the face to an area of the trigeminal nerve. After placing the needle, he or she will wake you and put an electrode through the needle to send an electrical current. This can heat up the nerve fibers and relieve pain caused by trigeminal neuralgia. If the symptom does not improve, then more heat might be needed. Temporary numbness on the face would happen after radiofrequency thermal lesions. The effect can last around 3 to 4 years. [6]
