Trigeminal neuralgia belongs to neuropathic pain, so first of all, we should go to neurology to clearly diagnose whether it is primary trigeminal neuralgia or secondary trigeminal neuralgia. For secondary cases, we have to remove the tumor compressing the nerve in neurosurgery, and the pain will disappear naturally after the operation. For patients with primary trigeminal neuralgia, the pain is not very obvious in the early stage of onset and the interval is long, so they can be treated with oral medication, the most common and the most effective medication is carbamazepine. For primary trigeminal neuralgia pain greater than six months, severe pain, poor drug effect, and seriously affect the life of workers, you can go to the functional neurosurgery department to consider microvascular decompression surgery treatment, the surgery is immediate and effective, the surgery is minimally invasive surgery, fast recovery. For elderly patients with severe pain, especially combined with cardiovascular or cerebrovascular diseases or other diseases, and those who have contraindications to surgery, they can go to the pain department to specifically adjust the drug treatment, or they can perform radiofrequency thermal coagulation destruction surgery in the pain department, or balloon compression and other less invasive surgery, but the pain is easy to recur and the incidence of facial numbness is high.
