Preservation of the Lesser Occipital Nerve Prevents Occipital Sensory Disturbance After Microvascular Decompression: Long-Term Results

摘要

BACKGROUND: In microvascular decompression (MVD) surgery for hemifacial spasm (HFS), preservation of the lesser occipital nerve (LON) will prevent occipital sensory disturbance, a frequent complication of MVD, but the long-term outcome is unknown. This study was designed to evaluate the long-term efficacy of LON preservation.
