Trigeminal neuralgia, also known as the “first pain in the world”, can often be diagnosed clearly with typical onset characteristics. Modern medical research has found that, except for a small number of trigeminal neuralgia caused by secondary factors such as tumors and vascular lesions, the majority of trigeminal neuralgia is primary, and is currently believed to be mainly caused by vascular compression of the root of the trigeminal nerve in the cranium. There are many drugs for the treatment of trigeminal neuralgia, some drugs can cause serious consequences when used improperly, such as the commonly used drug carbamazepine, common side effects include dizziness, drowsiness, dry mouth, nausea, skin allergy rash, and in severe cases, ataxia, diplopia, convulsions, aplastic anemia, liver and kidney function damage, angina pectoris, coma, abnormal mental symptoms, etc. It is contraindicated for pregnant women during pregnancy. Phenytoin sodium: with symptoms such as dizziness and unstable walking. Gabapentin, with adverse reactions such as drowsiness and vertigo, is contraindicated in pregnant women. Pregabalin, with adverse reactions such as dizziness and drowsiness, should not be stopped suddenly, and should be taken gradually in reduced doses. Therefore, patients with trigeminal neuralgia should use the drug safely under the guidance of a doctor. Many patients have been carrying the disease and taking medication for a long time because of the lack of effective treatment, and often the condition is not effectively controlled, but brings great harm to the body. Drug therapy is not the best treatment. Excluding drug therapy, it has many treatment methods, acupuncture therapy, closure therapy, physiotherapy, tissue therapy, radiofrequency temperature-controlled thermocoagulation of the semilunar ganglion, microvascular decompression, etc. can be applied in the treatment of trigeminal neuralgia. Among them, drug therapy is one of the preferred methods, and apparent microvascular decompression is the preferred surgical method. Surgical treatment of trigeminal neuralgia: Surgery is required for a complete cure. The surgical treatment for trigeminal neuralgia is microvascular decompression. Surgery has gradually matured and is widely used in the treatment of trigeminal neuralgia and other diseases. It has been widely used in the treatment of trigeminal neuralgia and other diseases. It has good clinical results, high cure rate and quick recovery, and is well received by patients. The principle of surgical treatment of trigeminal neuralgia is to separate the compressed nerve vessels under the operation of microscope. Thus, the compression of the nerve root by the blood vessels is released and the normal function of the nerve is restored. The pain disappears immediately after surgery in the majority of patients, and normal facial sensation and function are preserved, without affecting the quality of life. It is the best treatment method to relieve trigeminal neuralgia. Microvascular decompression is a treatment known to treat trigeminal neuralgia with complete preservation of nerve function. The procedure is performed under general anesthesia, and the surgical incision is made in the hairline behind the ear to release the compression of the blood vessels on the nerve root, restore the normal function of the trigeminal nerve, and make the pain disappear. The procedure has the advantages of short time, less bleeding, fewer complications, less pain, and quicker results, and the whole procedure is performed under a microscope.
