title: Atrophy of corrugator supercilii muscle in a patient induced by the onabotulinum toxin injection.
abstract: Onabotulinum toxin has been used to treat a variety of headaches. We report a case of a 29-year-old woman who developed temporary and reversible atrophy of corrugator supercilii muscle after onabotulinum toxin (Botox, Allergan, Irvine, CA, USA) injection. To our best knowledge this has not been described in the literature before.
