The brow lift sign is co-contraction of the frontalis and orbicularis oculi causing simultaneous eye closure and paradoxical elevation of the eyebrow during a spasm. This movement is impossible to execute voluntarily and does not occur in blepharospasm. It seems very specific for HFS. (3). The brow lift sign was described by Babinski and is one of several signs referred to as “the other Babinski sign.”
 
Video legend. Left hemifacial spasm, much improved after botulinum toxin injections.
