Botox temporarily blocks the neuromuscular junction of the facial muscles to suppress spasms, and needs to be repeated every 3 to 6 months. Microvascular decompression (MVD) is surgery that resolves the underlying cause, the vascular-nerve compression, and has a high cure rate, but it involves general anesthesia and a craniotomy. Korean medicine treatment sits between these two: it reduces the frequency and intensity of spasms, helps lengthen the interval between repeat procedures, or manages symptoms while waiting for surgery. In early and mild cases, it can sometimes produce meaningful improvement on its own.
