Abstract：Primary hemifacial spasm (HFS) is a disorder that causes frequent involuntary contractions in the muscles on one side of the face, due to a blood vessel compressing the nerve at its root exit zone (REZ) from the brainstem. Numerous prospective and retrospective case series have confirmed the efficacy of microvascular decompression (MVD) of the facial nerve in patients with HFS. However, despite the support for efficacy of MVD in treating FHS, there remain concerns over sig-nificant postoperative complications. In this paper, recent technological advances related to MVD (such as lateral spread re-sponse, brainstem auditory evokes potentials, three dimensional time of flight magnetic resonance angiography and intraopera-tive neuroendoscopy) are reviewed in an effort to improve MVD outcomes and reduce postoperative complications.
