Observations indicate hemifacial spasm severity is predicted by Babinski sign and vascular compression, suggesting a need for tailored surgical strategies.
The other Babinski sign is a significant clinical indicator of more severe HFS and is strongly associated with the η-like VA-PICA compression pattern. This sign may aid in preoperative assessment by predicting HFS severity and specific underlying vascular NVC morphologies, potentially informing surgical strategy.
