The face has rich blood vessels and nerves, which can adjust and adapt itself to the changes in external temperature, and in general mood, people’s face rarely appears diseases. In recent years, due to the invasion of trigeminal neuralgia disease, more and more people have the symptoms of facial pain, especially when the pain appears when the patient speaks, eats, brushes teeth, washes face, etc., which seriously affects the patient’s normal. Trigeminal neuralgia is a relatively common neurological disease, mostly caused by vascular compression of the trigeminal nerve, and its main clinical symptom is pain, mainly manifested as severe pain in the distribution area of the facial trigeminal nerve, with lightning recurrent attacks. The disease mostly occurs in middle-aged and elderly people, with slightly more female patients than male patients, and most patients have unilateral onset, with right-sided onset being more common and very few having bilateral onset. If it is not effectively treated for a long time, the pain will become more and more serious. That trigeminal nerve treatment, trigeminal neuralgia hanging neurosurgery or pain department. The best way to treat trigeminal neuralgia according to its etiology is surgery, so patients should hang neurosurgery. At present, the neurosurgery department carries out “microvascular decompression” surgery to treat trigeminal neuralgia according to the cause. The principle of treatment is to find the blood vessel that is compressing the trigeminal nerve according to the cause of the disease, so that the trigeminal nerve can be decompressed and the pain symptoms can disappear. The neurosurgery department has rich experience in the treatment of trigeminal neuralgia, especially in the operation technique of microvascular decompression for trigeminal neuralgia, which is operated skillfully and without the slightest error to ensure the safety of the operation.
