Laryngeal dystonia is a chronic neurologic disorder characterized by intention-induced spasms of the vocal folds driven by aberrant central motor processing. The use of in-office transcervical botulinum toxin injection for the treatment of laryngeal disorders, such as laryngeal dystonia, has been deemed safe and efficacious. There is, however, no available data outlining the hemodynamic changes experienced by patients undergoing this frequently performed procedure.
