When it comes to trigeminal neuralgia, people may not be familiar with it. However, many people are troubled by inexplicable facial pain, which often manifests itself as a sudden onset of severe pain in one side of the upper and lower lip, gums and under the orbit, in front of the ear, forehead and other parts of the body, and can be triggered by talking and drinking during the attack. The term trigeminal neuralgia is only known to patients after tooth extraction. The diagnosis of trigeminal neuralgia comes mainly from the clinical diagnosis, based on the presence of a recurrent severe pain in the distribution area of the trigeminal nerve. The attacks are sudden, without any aura, and can be caused by brushing the teeth, washing the face, talking, cold stimulation, eating, etc. The pain is severe in the form of episodes of electric shock-like, knife-like, or tearing pain, with sudden onset and stop, and completely normal intervals. The pain lasts for a few seconds to 1 to 2 minutes each time, and the interval between attacks is gradually shortened and the pain is gradually increased. Conventional imaging examinations such as CT and MRI of the brain are mostly unremarkable. In some patients, vascular compression can be found in the trigeminal nerve region at the foot of the pontocerebellum. At present, the radical surgery with definite efficacy is recognized as radiofrequency thermocoagulation and microvascular decompression of the trigeminal nerve hemianopia. As medicine has evolved into the 21st century, minimally invasive surgery, as a development trend, has begun to be widely used in various fields that previously required open surgery. Electrophysiologically guided selective trigeminal nerve radiofrequency thermocoagulation is a minimally invasive nerve destruction therapy that uses controlled temperature to act on the neuronal cytosol within the ganglion, causing coagulation and denaturation of neuronal proteins and blocking nociceptive nerve conduction. By controlling the temperature of thermal coagulation, it is now possible to destroy mainly the nociceptive nerves while preserving most of the tactile and motor nerve functions, so that the concern about the crooked eyes and slanted mouth after nerve destruction is unnecessary. Because thermocoagulation is effective, has few complications, can be tolerated by elderly, frail and sick patients, and can be repeated, it has become one of the major procedures for the radical treatment of trigeminal neuralgia. This type of surgery is performed in regular hospitals, with relatively complete anesthesia and monitoring, and the operation usually takes 30-60 minutes, including sterilization, positioning, radiofrequency needle puncture, testing and radiofrequency thermal coagulation, etc., which requires less than ten minutes of general anesthesia, and the patient recovers quickly after the operation, and can be awake in the operating room and accurately answer the doctor’s questions, verify the efficacy of the operation, and even finish pressing the puncture point with their own hands to prevent The patient can even perform the action of pressing the puncture site with his own hand to prevent subcutaneous bleeding. After the surgery, there will be numbness and numbness in the innervated area of the trigeminal nerve branches, and this numbness will gradually decrease with time, and usually only a slight numbness will remain after 3-6 months after the surgery. The recent efficiency of the total surgery exceeds 99%, and the 5-year recurrence rate in the long term is about 15%. Radiofrequency ablation of trigeminal neuralgia in the trigeminal nerve hemimelia, as the saying goes, acts on the neuronal cell body, and the chance of nerve regeneration is relatively low, thus the recurrence rate is much lower than that of trigeminal nerve peripheral branch destruction treatment. Since the minimally invasive surgery has less impact on the functional status of the patient’s respiratory and circulatory systems, it is especially suitable for elderly patients with combined chronic diseases, and the complications such as bleeding and infection during and after surgery are also less than those of open surgery. In this way, the minimally invasive treatment through a special “needle” reaches the cause of the disease, eliminates the pain and gives the patient a clear sky.
