[Abstract] Primary hemifacial spasm is the abnormal movement of facial muscles caused by the compression of facial nerve by blood vessels, which seriously affects patients' quality of life. The operation of microvascular decompression is the most effective method to treatment hemifacial spasm. High resolution imaging of the facial nerve and its ambient blood vessels was performed before surgery to accurately locate the compression site, providing the reference for making surgical plans and predicting surgical outcomes. The development of magnetic resonance neurovascular imaging sequence and post-processing technology provides an accurate image method for preoperative judgment of the relationship between facial nerve and vessels. This article reviews magnetic resonance cisternography and angiography techniques, image reconstruction and fusion techniques, clinical manifestations of vascular compression in different areas of facial nerve, the correlation between neurovascular relationship and surgical prognosis in patients with facial spasm.
