How does BOTOX help?

Botulinum toxin A (BOTOX®) injections have been performed for the treatment of Spasmodic Dysphonia (SD) for over 20 years. The safety and efficacy of this procedure has been extensively documented in the medical literature. These injections help control the vocal spasms associated with SD by temporarily weakening the vocal fold muscles enough to allow smoother voicing. Once the injection wears off, the voice begins to spasm again and another injection is required (typically, every 3 months).

More information about the use of BOTOX® in treating SD can be obtained by visiting the website for the National Spasmodic Dysphonia Association, ( a nonprofit group dedicated to the needs of those with spasmodic dysphonia. Patients may also find it helpful to speak to others with SD about their diagnosis, symptoms and treatment options, and are encouraged to contact the local SD support group through its leader, Mary Bifaro – 704.846.3519 or
