Patients afflicted with neurological voice disorders (spasmodic dysphonia) are treated using botulinum toxin injected into the vocal cords. Botox injections are most commonly used in a voice clinic setup to fix a rare voice disorder Spasmodic Dysphonia. This injection is known to temporarily paralyse the excessive muscle activity thereby leading to a less strained voice quality.
Typically in a Botox clinic the patient is injected with appropriate doses of botox injection (unilaterally or bilaterally) and deserved for change / improvement in voice quality.
This is further followed on by regular sessions of voice therapy. The injection is given on an outpatient basis and under laryngoscope or EMG guidance.
Injections of tiny amounts of purified botulinum toxin into your neck skin can decrease muscle spasms or abnormal movements.
Sometimes one vocal cord may stop moving (become paralyzed). If you have one paralyzed vocal cord, you might often complain of hoarseness. You might also complain of choking when you drink liquids, but rarely have trouble swallowing solid foods. Sometimes the problem goes away with time.
If not, fat or collagen injection can be used. Body fat or synthetic collagen is injected, either through your mouth or the skin on your neck, to add bulk to the paralyzed vocal cord or to treat vocal cord weakness. The material fills the space next to your vocal cord and pushes it closer to your other vocal cord, allowing them to vibrate more closely together.
BOTOX injections provide many SD patients with the freedom to speak more easily. While not a cure, most patients notice a marked improvement in voice quality and speaking effort. The benefits of BOTOX, which usually last from three to six months, are doubled with Speech Therapy sessions.
Even though the technique and dosage are the same each time, results can vary. This can be due to many reasons, including small, unavoidable differences in placement of the medication in the very tiny vocal fold muscle.
Results always vary among patients, because of individual differences in sensitivity to the medication. Some patients experience smooth voices for longer periods of time than other patients, while others may develop recurrent spasms, breathiness or hoarseness. It is difficult to predict exact results in each patient.
For next three to six months your voice will seem normal. Talking will be easy. With continued speech therapy during this phase, the effects of the Botox will last twice as long than without therapy.
