Almost one in ten people in China suffer from migraine, and there are more men than women. The headache is mostly lateral, mainly around the occipital, ear-temporal and orbital areas, and lasts for 4-72 hours, accompanied by nausea, vomiting and sensitivity to sound and light. Migraines are at high risk of triggering depression, suicide, and cerebral infarction. Mild migraines can be treated with medication and the symptoms can be relieved. However, for some refractory and intractable migraines where medications are ineffective, patients may consider microvascular decompression. Microvascular decompression is a minimally invasive procedure that requires no craniotomy, a 3-5 cm incision behind the ear, careful microscopic observation of the nerve in relation to the surrounding blood vessels, and precise targeting of the responsible blood vessel that is compressing the nerve, careful release of the compression or entanglement, and isolation of the nerve. Excellent results. Post-operative recovery is quick, no scars are left, and the patient’s appearance is not affected.
