Is complete elimination of lateral spreading response essential in microvascular decompression for hemifacial spasm?
Complete elimination of LSR is not essential for clinical success in MVD for HFS. A quantitative reduction in LSR amplitude, especially in the mentalis muscle, provides a robust and practical intraoperative predictor of both objective and subjective outcomes. These findings advocate for a shift toward a muscle-specific, threshold-driven strategy for intraoperative neurophysiological monitoring in HFS surgery.
