How I do it: endoscopic microvascular decompression for hemifacial spasm associated with the vertebral artery

Background Microvascular decompression (MVD) of hemifacial spasm (HFS) associated with the vertebral artery (VA) shows higher rates of incomplete cure and complications compared to non-VA-related HFS. Method Purely endoscopic MVD for VA-associated HFS via a retrosigmoid keyhole was performed. Neurov...

Description
Summary:Background Microvascular decompression (MVD) of hemifacial spasm (HFS) associated with the vertebral artery (VA) shows higher rates of incomplete cure and complications compared to non-VA-related HFS. Method Purely endoscopic MVD for VA-associated HFS via a retrosigmoid keyhole was performed. Neurovascular conflicts by a directly offending artery and VA around the root exit zone of the facial nerve were clearly demonstrated under 30° endoscopic view without significant cerebellar retraction. The VA and directly offending artery were safely transposed with preservation of perforators under excellent view. Conclusion Endoscopic MVD offers reliable decompression for VA-associated HFS with minimal invasiveness.
