Migraine is a very common clinical disorder, a primary type of headache, with a very high incidence. According to statistics, the prevalence of migraine in the population is as high as 9.3%, which means that almost one in ten people suffer from migraine on average. Migraines are divided into migraines with aura and migraines without aura. Migraine with aura is only a small percentage, about 10%. Some patients may have obvious prodromal symptoms before or during the onset of headache, such as fatigue, lack of concentration, drowsiness, etc. Some patients may have blurred vision, dark spots or bright lights in front of their eyes, or abnormal sensation, and a small number of patients may have speech aura or motor aura. Most people have migraine without aura, or common migraine, with no obvious aura symptoms before the onset of migraine. At present, there are various theories about the pathogenesis of migraine, among which the vascular nerve compression theory is dominant and has strong persuasive power to explain the onset of migraine scientifically. According to this theory, the blood vessels and nerves on the scalp of ordinary people are in a companion relationship and do not compress or interfere with each other, and the nerves are not subject to abnormal stimulation; however, the blood vessels and nerves on the scalp of migraine patients have abnormal alignment due to some reasons, and the blood vessels cause abnormal compression, adhesion or entanglement to the relevant nerves. The concentration of neurotransmitters in the blood may change under certain conditions, such as mood swings or endocrine changes, which may cause abnormal stimulation of the nerves in the compressed segment, thus causing headache attacks. Migraines are usually moderately severe, throbbing headaches or dull, swollen pains, and are usually fixed-site, stereotypical attacks. The pain sites are mainly the auriculotemporal, orbital, and retro-occipital regions, and the corresponding nerves involved are the auriculotemporal, supraorbital, and greater occipital nerves, which are the three most common sites for migraine, and occasionally the lesser occipital and greater auricular nerves. Some migraines are painful on one side, some patients have bilateral pain, and in severe cases the pain can radiate to the entire scalp. Many patients have pain attacks accompanied by nausea and vomiting, fear of light and noise, and other accompanying symptoms. This is mainly because the stimulation of the nerves is transmitted to the brainstem with the nerve alignment, and some symptoms of the brainstem occur. In addition, migraine attacks have a distinct interval, and when they do not occur, they are like normal people, but once they do, the pain can be very intense. Although migraine is a common disease, many local primary care hospitals often do not have particularly effective treatments for migraine, and often take conservative medical treatments, such as taking pain medications, such as acupuncture, gua sha, massage, physical therapy, etc., but they are often ineffective. For mild migraines, there may be some relief, while for intractable migraines there may be little effect. So patients with intractable migraines need to find a more effective treatment. Currently, microvascular decompression is an effective treatment. Microvascular decompression is a surgical treatment based on the theory of vascular nerve compression in migraine headache, in which the vascular nerve compression point on the scalp is found under the microscope, the responsible blood vessel of the nerve compression is nudged away, and the nerve is isolated and protected by the anti-adhesive membrane, so that the nerve is no longer abnormally stimulated and the migraine is treated.
