Trigeminal neuralgia is the most common neurological disease of the brain, mostly occurring after the age of 40, with the majority of female patients. The clinical symptoms are mainly recurrent paroxysmal severe pain in the distribution area of the trigeminal nerve on one side of the face. The pain is lightning-like or knife-like, lasting for several seconds or minutes, and it occurs periodically, which is unbearable. Due to the existence of pain “trigger points”, patients often have attacks when washing their faces, brushing their teeth, talking, eating, and sometimes even when walking or swallowing saliva in the breeze. Therefore, the patient’s normal life and work are greatly affected. In the treatment method, patients will first think about what drugs can cure them, so can trigeminal neuralgia be cured by taking drugs? Drug treatment as a general conventional treatment, clinical western medicine is the main choice, the first choice is carbamazepine, oxcarbazepine, about 90% of patients can achieve complete pain relief in the early stage, a small number of patients can not tolerate the side effects of drugs, you can try phenytoin sodium, methylcobalamin tablets and other drugs. However, drug treatment can treat the symptoms but not the root cause, as many patients say, “It doesn’t hurt when you eat, but it will come back when you stop taking it.” It is suitable for patients with early mild attacks that are infrequent, while for severe patients with frequent attacks, increasing the dosage of drugs will bring great side effects, such as severe dizziness and blurred vision, which patients cannot tolerate. Trigeminal neuralgia can not be cured by medication, what method can cure it? Many other patients in the clinic choose acupuncture and gamma knife treatment, but these are also temporary pain relief, easy to relapse later, long-term repeated acupuncture and gamma knife treatment, also bad for the nerve. In order to cure trigeminal neuralgia, it is necessary to find out the cause of treatment. At present, trigeminal neuralgia is clinically classified into primary and secondary according to the etiology. Secondary trigeminal neuralgia is mostly caused by tumor compression, inflammation, vascular malformation and other obvious organic factors and functional lesions, and the pain is often persistent, and the lesion signs of the adjacent structures of the trigeminal nerve can be detected according to the relevant examination, so the treatment is easier. In primary trigeminal neuralgia, no clear cause can be found, and it is now generally believed that this type of pain is caused by pulsatile vascular compression of the sensory roots of the trigeminal nerve into the pontocerebrum (REZ). According to this theory, treatment is carried out by microvascular decompression, in which an opening is made behind the affected ear, the responsible vessel and nerve are observed and identified under a microscope, and a spacer of special material is placed between the vessel and the nerve to achieve the disappearance of trigeminal neuralgia after surgery. The procedure is minimally invasive, safe, does not cut the nerve, preserves the integrity and physiological function of the trigeminal nerve, and preserves facial sensation after surgery. It has become the internationally recognized method of choice for the treatment of trigeminal neuralgia.
