When it comes to migraine, we are not unfamiliar with it, because it is not uncommon and has been recorded in ancient books as early as 2500 years ago. There are many clinical types of migraine, and the most common type is intractable migraine, which has many attacks, long duration and severe pain, which not only affects patients’ health, but also their life, work and study. From ancient times to the present, the widely used treatments for migraine are traditional conservative treatments, mainly including drugs, acupuncture, cupping and other physical methods, all of which aim to abort the course of the disease or relieve the headache. However, according to the long-term postoperative follow-up, these traditional methods have been found to be effective in relieving pain for patients with mild symptoms, but they can do nothing for intractable migraines. At present, based on the doctrine of vascular compression of nerves, the medical community has discovered that the relationship between blood vessels and nerves in the scalp of normal people is companionship, while the blood vessels and nerves in patients with intractable migraine are compressed and entangled with each other, and under certain specific factors, the blood vessels become dilated, the neuromediators increase, and the pain signals are transmitted to the human brain through the human sensory organs, and migraine occurs. This profound interpretation of the doctrine is recognized by many neurosurgeons. Therefore, for the treatment of migraine, it is only necessary to separate the nerves from the blood vessels reasonably and effectively through surgery, so that they can return to their normal operation and thus migraine can be avoided. So, about the surgical treatment of intractable migraine. The microvascular decompression procedure currently carried out is fully in line with the principle of vascular pathogenesis. The procedure is a subcutaneous surgery without craniotomy, and the pain site is found by nerve block test before surgery, and then 2-5 cm incisions are made in the orbital, auriculotemporal, and retrooccipital areas to precisely find the pressure points of nerves and blood vessels and isolate them, and the headache symptoms disappear significantly after surgery.
