[Pure Endoscopic Microvascular Decompression for Trigeminal Neuralgia and Hemifacial Spasm].

The panoramic view offered by endoscopy has been used to observe neurovascular compression in endoscope-assisted microsurgery to compensate for the blind spots in microvascular decompression(MVD)for trigeminal neuralgia and hemifacial spasm. In recent years, purely endoscopic MVD has been performed as a minimally invasive surgery and has become a new surgical technique for MVD. Endoscopic MVD has gained acceptance, and further developments are expected. Here, we present endoscopic MVD, including the setup, equipment, surgical procedures, and decompression techniques by transposition, as well as representative cases, and discuss the future prospects and possibilities of endoscopic MVD.
