Surgical Outcome of Microvascular Decompression for Hemifacial Spasm: Symptom Control and Quality of Life

Abstract

Introduction Hemifacial spasm (HFS) is characterized by a segmental myoclonus of the face muscles innervated by the ipsilateral facial nerve. The accepted pathophysiology of HFS suggests that it is a disease process of the nerve root entry zone associated with any neuro-vascular conflict.
