Measurement of the Anatomic Position of the Corrugator Supercilii

Abstract

There is variability in the location of the corrugator supercilii that is not gender dependent. When injecting botulinum toxin into the corrugator supercilii, it might be advantageous if the lower forehead skin of the brow is elevated, thus allowing for more precise injection. This may achieve weakness of the targeted muscle with lower doses of botulinum toxin, thus lessening the risk of eyelid and brow ptosis.
