According to statistics, there are nearly 30 million people suffering from migraine in China, and the incidence of migraine is gradually increasing in children and adolescents. The causes of migraine are still unclear. High emotional tension, overload of mental stress, overwork, and poor life and diet and habits may all be important factors in triggering migraine. As most migraineurs do not pay attention to the headache at the initial stage and do not treat it regularly, it turns into intractable migraine. Severe migraine can trigger mental disorders such as depression and phobias, so the World Health Organization has even designated severe migraine as one of the most disabling chronic diseases, similar to dementia, tetraplegia and severe mental illness. According to the report, intractable migraine is one of the most difficult disorders in the world to control. It is characterized by recurrent severe headaches mainly in the frontal, temporal, periorbital and posterior occipital areas on one or both sides, and the nature of the headache is fluctuating pain, but there are also non-volatile pains such as distension and tightness. It is difficult to express the degree of pain in words, and most patients have nausea, vomiting or fear of light and sound when the pain attacks. Migraine has traditionally been treated by Chinese and Western medicine, but medication can only relieve or delay the pain attacks but not cure migraine. According to some scholars, the normal blood vessels and nerves on the scalp have a companion relationship and do not compress each other, while the blood vessels and nerves in migraine patients cause abnormal compression or entanglement of the nerves due to various reasons. When the blood vessels in the compressed segment change, the blood vessels in the compressed segment produce an abnormal stimulation to the nerves and cause headache attacks. The headache can be treated after the nerve decompression surgery is performed to relieve the compression of the nerve by the blood vessel. The procedure is a minimally invasive surgery that is performed under a microscope, because it is performed on the scalp outside the skull under local anesthesia, and the incision in the hairline is only about 3 cm. The operation usually takes about 45 minutes to an hour, and the patient is basically pain-free during and after the operation.
