Dysphonia - spasmodic
Patients with spasmodic dysphonia should see an ear, nose, and throat doctor to check for changes in the vocal cords and other brain or nervous system problems.
Botulinum toxin (Botox) treatments may help. Botulinum toxin comes from a specific type of bacteria. Very small amounts of this toxin may be injected into the muscles around the vocal cords. This treatment will often help for a period of 3 to 4 months.
Surgery to cut one of the nerves to the vocal cords has been used to treat spasmodic dysphonia, but it is not very effective.
