Trigeminal neuralgia belongs to the facial nerve disease, mainly due to the abnormal discharge between the bonding and compression of nerves and blood vessels in the cranial brain, in the area of the trigeminal nerve appears paroxysmal unbearable pain, the nature of the pain is like a knife cut like fire, come and go without any signs, even loud speech will be at any time to incur trigeminal neuralgia lightning-like erosion. Three methods of treating trigeminal neuralgia: drugs: oral drugs can play a temporary role in pain relief or alleviation, such drugs are resistant, the oral dose gradually increases, the effect is getting worse, its side effects are large, long time to take can cause granulocytopenia, simple thrombocytopenia, leading to blood disorders, and can make memory loss, vision, hearing loss, liver function damage, etc. This is the most common treatment of trigeminal neuralgia. method. Gamma knife: The treatment principle is to focus gamma rays on the pre-selected pain-related brain nuclei or nociceptive conduction pathways, a large dose of irradiation to destroy the nociceptive conduction pathways, blocking the conduction of nociception to achieve the analgesic effect, and the surgical treatment process is simple, but easy to recur, there are certain sequelae and risks, and can not be completely cured. Microvascular decompression: The most important surgical treatment for trigeminal neuralgia is microvascular decompression, because 70% of patients have trigeminal neuralgia caused by nerve compression of blood vessels, and microvascular decompression is the only method to treat the cause of trigeminal neuralgia and facial spasm. The advantages of microvascular decompression for trigeminal neuralgia Microvascular decompression only requires a small incision in the occipital area behind the patient’s ear to expose the nerve compression by the blood vessels, and a special pad is placed between the nerve and the blood vessels to separate the nerve and blood vessels. This procedure does not cut the nerve, preserves the integrity and physiological function of the trigeminal nerve, and preserves facial sensation after surgery. It makes the majority of patients more willing to accept the treatment. Therefore, it is internationally recognized as the safest and most effective method to treat trigeminal neuralgia.
