Botox®, botulinum toxin, is a paralytic agent that is commonly used for management of wrinkles and other forms of neurological muscle disorders (dystonias). Studies have shown that is highly effective for management of spasmodic dysphonia when injected into the muscles of the larynx
. In this application, it is used to weaken the muscles of the larynx, which is believed to reset the brain to allow for normal phonation.
At our center, the procedure is performed under electromyographic (EMG) guidance to ensure the appropriate amount of Botox® is applied to the targeted muscle.
The procedure typically lasts fewer than 10 minutes. Patients find that they may have a period of breathy voice following the procedure, which lasts from days to weeks.
Following resolution of breathy voicing, the patient is often able to voice normally for an extended period of time ranging from two to four months although results vary. Repeat injections are often required to manage the symptoms of spasmodic dysphonia, and the scheduling of injections is tailored to each patient’s needs.
