Microvascular decompression (MVD) is known for its curative treatment. Lateral spread response (LSR) is a kind of pathologic electromyographic (EMG) wave form which develops when facial nerve is compressed by vessel. There have been reports of monitoring LSR during MVD surgery helps predicting the clinical outcome of MVD.\n\nAs neuromuscular blockade during LSR monitoring decreases the amplitude of EMG, partial neuromuscular blockade is usually maintained during general anesthesia for MVD. However, there have been no evidence of which degree of partial neuromuscular blockade should be performed or no neuromuscular blockade could be performed during LSR monitoring.
