Microvascular decompression using a fully transcranial neuroendoscopic approach

Abstract

Objective To evaluate the effectiveness and safety of microvascular decompression (MVD) using a fully transcranial neuroendoscopic approach. Methods Thirty-one patients who underwent MVD using a fully transcranial neuroendoscopic approach in our department between May 2016 and September 2019 were retrospectively reviewed. Results All patients successfully underwent MVD, and immediate pain relief was achieved in all 17 cases of trigeminal neuralgia (TGH) and 3 cases of glossopharyngeal neuralgia (GPN). Hemifacial spasm (HFS) was completely resolved in all 11 patients. No mortality or permanent complication was seen. Conclusions The endoscope is a useful tool for confirming vascular conflict identified by the microscope and is helpful in detecting the vessel responsible for neuralgia without retracting the brain and nerves. MVD using a fully transcranial neuroendoscopic approach is an effective and safe alternative to endoscopic-assisted MVD and traditional MVD.
