Recent Advances in Intraoperative Brainstem Auditory Evoked Potential Monitoring during Microvascular Decompression Surgery for Hemifacial Spasm

Brainstem auditory evoked potential (BAEP) testing during microvascular decompression (MVD) is very important in the treatment of hemifacial spasm (HFS). The reason for this that vestibulocochlear nerve located immediately next to facial nerve, so may be affected by manipulation surgery. BAEP detecting damage has been further developed use In most HFS patients with normal nerves, degree caused surgery well-reflected test waveforms. Therefore, real-time best way minimize nerve. purpose study was review recently published waveforms were obtained MVD determine relationship between and
