title: Ear wiggling tics: treatment with botulinum toxin injection.
abstract: Ear wiggling tics are a rare disorder and there is no reported satisfactory treatment. We had a patient present with ear wiggling tics, which we treated with injections (totaling 40 units) of botulinum toxin A to the pinna muscle (i.e., the auricularis anterior and superior). The tics completely disappeared within 9 days of injection without any side effects.
