Intra-operative neurophysiology during microvascular decompression for hemifacial spasm

Highlights ► This work contribute to the better understanding pathophysiology of the hemifacial spasm (HFS). ► During MVD changes in: facial corticobulbar motor evoked potentials (FCoMEPs), blink reflex, F wave and lateral spread responses (LSRs) were presented.. ► The data support the theory that h...

Description
Summary:Highlights ► This work contribute to the better understanding pathophysiology of the hemifacial spasm (HFS). ► During MVD changes in: facial corticobulbar motor evoked potentials (FCoMEPs), blink reflex, F wave and lateral spread responses (LSRs) were presented.. ► The data support the theory that hyperexcitability of facial nerve in HFS is not caused only by pulsating vessels at the REZ but also by antidromic activation of the facial motor nucleus.
