Spasmodic-dysphonia

                                                             Spasmodic Dysphonia

Spasmodic dysphonia is a voice disorder that involves the muscles of the throat that control speech. Spasmodic dysphonia causes strain and difficulty in speaking.


Procedure:

The injection of Botulinum toxin (Botox)-


The Botulinum toxin which is a biological product is injected into specific muscles where it acts to reduce the involuntary contractions that cause the symptoms of spasmodic dysphonia. The injections weaken muscle activity sufficiently to reduce a spasm but not enough to cause paralysis. Local injections of botulinum toxin (BTX) into the vocal cord muscles have proven to be the most effective treatment for spasmodic dysphonia. The treatment weakens the vocal muscles so that spasms are greatly diminished and speech is greatly improved. The treatment can also reduce the breathiness and help decrease the effort required to speak.

Medicinal treatment-
Oral medications provide little relief in the symptoms of spasmodic dysphonia, but if other forms of dystonia are present, medications may help relieve those related symptoms. There are several possible categories of medications used in the treatment of dystonia including anticholinergics, benzodiazepines, and baclofen. The treatment of spasmodic dysphonia must be tailored to the individual patient.

Surgical treatment-


Surgery for spasmodic dysphonia has recently been re-examined as a form of treatment for people for whom botulinum toxin injections are no longer providing relief of symptoms. Selective Laryngeal Adductor Denervation Reinnervation surgery involves cutting the nerve to the affected vocal cord and reinnervating the muscle with another muscle to prevent muscle atrophy.
