Trigeminal neuralgia is a severe unilateral or bilateral paroxysmal pain in the face that is extremely painful and difficult to treat. It has burning pain, tearing pain, cone pain, and electric shock pain. It is called “the world’s number one pain” or “the cancer that never dies” by the people. This disease seriously affects the life and health of patients. Due to the long-term torture of the disease, some patients even have the idea of light-heartedness. Pain can be caused by wind, touch, smiling, eating, and other minor stimuli, or it can be spontaneous. The degree and nature of pain varies from one site to another, with more people suffering from pain in branches II and III and fewer developing in branch I. There are many causes of trigeminal neuralgia, generally speaking, it can be divided into two aspects. One is caused by intracranial compression by blood vessels, with the expansion and beating of blood vessels causing impact on the trigeminal nerve, causing pain in the distribution area of the trigeminal nerve. Another reason is that the trigeminal nerve has a very thick ganglion in the skull. This ganglion is called the trigeminal semilunar ganglion. Tumors, ischemia and infection of the ganglion can cause trigeminal neuralgia. The treatment methods for trigeminal neuralgia are mainly divided into three categories, which are recognized as effective methods at home and abroad. The first method is medication, which mainly allows patients to take oral medications, and the medications include carbamazepine, gabapentin, oxcarbazepine, etc. This kind of medication is effective for many patients. Patients may prefer to take oral carbamazepine for pain relief. The second method is minimally invasive interventional treatment, also known as trigeminal nerve hemimelia disruption. This can be done using either chemical disruption or radiofrequency thermocoagulation techniques. The former involves puncturing the nerve or ganglion with a nerve block needle and injecting drugs to destroy the responsible nerve; the latter involves placing a very thin radiofrequency needle into the trigeminal meningeal ganglion, and this needle tip can be heated to 70 to 80 degrees, causing a slight denaturation of the proteins within the meningeal ganglion so that pain signals cannot be transmitted. The third method is neurosurgery, also called microvascular decompression. It involves opening the back of the head to relieve the compression of blood vessels on the trigeminal nerve. Each of these three methods can be used for patients with different levels of pain. Advantages of interventional treatment for trigeminal neuralgia: no side effects, minimally invasive, low risk Medication should be preferred in the initial stage of trigeminal neuralgia. Usually, doctors will recommend medication for patients with less severe symptoms. However, drugs cannot be used for long-term treatment after all. Although drugs such as carbamazepine have certain effects, long-term high doses can lead to serious side effects. Therefore, the disadvantage of medication in the treatment of trigeminal neuralgia is its transient nature. However, radiofrequency intervention for trigeminal neuralgia is treated by puncturing radiofrequency, which can mostly solve the problem in one puncture without side effects. Compared to medication for trigeminal neuralgia, treating trigeminal neuralgia with interventional treatment will produce a once-and-for-all effect. It is much less invasive and risky than traditional surgical treatment of trigeminal neuralgia. In general, surgical treatment of trigeminal neuralgia is more risky, although microvascular decompression is said to be very effective for the treatment of trigeminal neuralgia, although the need for surgery and the risks associated with surgery often discourage patients. In addition, older patients with trigeminal neuralgia are not suitable. Interventional treatment of trigeminal neuralgia is virtually non-invasive due to the use of fine needle puncture. It is also possible to repeat treatment for patients with recurrence. There is no need to worry about the damage caused by repeated treatment. Patients can rest assured.
