Trigeminal neuralgia is one of the most common, stubborn and painful painful diseases in clinical practice. For trigeminal neuralgia, especially intractable trigeminal neuralgia, the pain department has a series of effective treatments: Drug treatment Carbamazepine, which is commonly used in the clinical treatment of trigeminal neuralgia. In addition to carbamazepine, there are a number of alternative drugs, such as phenytoin sodium and gabapentin. Non-invasive treatment Laser, super light, transcutaneous electrical stimulation and other treatments are simple, easy and safe, and have certain efficacy for some patients. Minimally invasive interventional procedures Trigeminal nerve destruction, i.e. injection of chemical drugs into the peripheral branches of the trigeminal nerve to directly destroy the nerve, commonly used drugs include anhydrous ethanol, phenol glycerin, adriamycin, etc. At present, physical destruction is mostly carried out, that is, the use of physical methods to achieve the purpose of nerve destruction, commonly used radiofrequency thermocoagulation, under x-ray fluoroscopy, with different sizes of radiofrequency needle under controlled temperature directly on the lesioned nerve, accurate positioning, small damage to the surrounding tissue, good treatment effect, less complications, especially for older, weak, multi-organ lesion patients can tolerate, for conventional methods It is suitable for patients whose treatment is ineffective or who have intractable trigeminal neuralgia. Thus, the pain department can treat trigeminal neuralgia with various methods, which is safe and effective and can keep the patients away from pain.
