Primary hemifacial spasm with few exceptions is due to the vascular compression of the
facial nerve that can be evidenced with high resolution MRI. Microvascular decompression …

BACKGROUND Microvascular decompression (MVD) is the surgical treatment of choice for
hemifacial spasm (HFS). During MVD, monitoring of the abnormal lateral spread response …

Objective In patients with hemifacial spasm, stimulation of a branch of the affected facial
nerve elicits an abnormal response in the muscles innervated by another branch. We tested …

OBJECTIVE Hemifacial spasm (HFS) is characterized by involuntary tonic and/or clonic
contractions of facial nerve muscles. Fully endoscopic microvascular decompression (E …

OBJECTIVE Hemifacial spasm (HFS) is a movement disorder characterized by involuntary
spasms of the facial muscles, and it can negatively impact quality of life (QOL). This …

Objective To examine a new abnormal muscle response (AMR) monitoring method during
microvascular decompression (MVD) for hemifacial spasm. Methods 486 patients with …

Background Microvascular decompression has been established as a primary treatment for
hemifacial spasm. Intraoperative monitoring is used during the surgery to guide …

OBJECTIVE The purpose of this study was to evaluate whether intraoperative monitoring of
lateral spread response (LSR) improves the efficacy of microvascular decompression (MVD) …

The trigeminal and facial nerves are placed at risk in a number of surgical procedures. The
use of electromyography, nerve conduction studies, somatosensory evoked potentials …

Objectives During microvascular decompression (MVD) of the facial nerve for hemifacial
spasm (HFS), an abnormal muscle response can be recorded upon stimulation of the facial …
