Although the nonaffected side appears to be clinically normal in hemifacial spasm (HFS), it is not known whether this side can be considered normal regarding histopathological findings. The purpose of this study was to objectively evaluate and compare orbicularis oculi samples of patients with HFS (not previously treated with botulinum toxin) and control patients undergoing cosmetic upper eyelid blepharoplasty.
