People who have never had trigeminal neuralgia can hardly understand what kind of pain it is. The pain is unbearable and painful, and it seriously affects the life and work of patients, and is called the “world’s first pain”. The treatment of trigeminal neuralgia includes conservative treatment and surgical treatment. Conservative treatment includes medication, closed treatment, physical therapy and so on. If conservative treatment is ineffective, surgical treatment can only be taken, and there are various surgical methods, including open surgery and minimally invasive radiofrequency thermal coagulation, which is currently used more often. Radiofrequency thermal coagulation is a minimally invasive surgery, radiofrequency current through the nerve tissue with a certain impedance, under the action of high-frequency current, heat is generated in the tissue, forming a certain range of protein coagulation denaturation, selectively destroy the fibers that conduct nociception, to achieve the purpose of treating trigeminal neuralgia. Radiofrequency thermocoagulation is less dangerous, easy to operate, simple, less painful, reliable, with slight tissue damage, and you can eat and live normally a few hours after the operation; treatment can be repeated if it is unsuccessful or recurs once. There are two types of radiofrequency thermocoagulation, one is radiofrequency thermocoagulation of the trigeminal ganglion and sensory roots through the foramen ovale, and the perforating needle enters the skull. This method has more postoperative complications: there is intracranial hemorrhage or hematoma, cerebral nerve injury, facial hematoma, etc. The other is peripheral nerve radiofrequency thermal coagulation therapy, which is to pierce the needle into the round hole, around the foramen ovale, supraorbital hole, infraorbital hole, chin hole, without entering the skull, so as to avoid intracranial complications and damage to cerebral nerves and cerebral vessels. This method has no other complications except for the appearance of facial nerve numbness and occasional local hematoma, and can achieve satisfactory results as well. With the passage of time, facial numbness will be gradually reduced, and there is no significant discomfort for patients after adaptation. By comparison, peripheral nerve radiofrequency thermal coagulation and temperature control treatment is a very ideal treatment method. As long as the needle is accurately positioned, only one needle is needed, and the pain of trigeminal neuralgia patients can be completely solved.
