Purpose of reviewTo review current concept in spasmodic dysphonia management. Recent findingsThe standard of care for spasmodic dysphonia in 2004 remains botulinum toxin chemodenervation for symptomatic management. This is supported by a large body of literature attesting to its efficacy in many different hands, particularly for the adductor form of the disorder. New surgical approaches await the crucial test of time, in view of historical difficulties in achieving long-term benefit via… 
Botulinum Toxin Therapy: A Series of Clinical Studies on Patients with Spasmodic Dysphonia in Japan
TLDR
A placebo-controlled, randomized, double-blinded clinical trial of BT therapy was conducted; this was effective and safe, and BT treatment is now funded by the Japanese medical insurance scheme.
Botulinum toxin injection for treatment of spasmodic dysphonia: experience at Srinagarind Hospital.
TLDR
Botulinum toxin therapy has become the standard care for the treatment of Spasmodic dysphonia and an acceptable and flexible treatment plan to produce a balance between decreased spasms and loss of function must be developed for each patient.
Life Threatening Delayed Complication of Botulinum Toxin Injection for Treatment of Spasmodic Dysphonia.
TLDR
The report of a delayed presentation of upper airway obstruction due to a complete vocal cords adduction requiring intubation ten days post Botox injection for the adductor form of spasmodic dysphonia is presented.
Botulinum toxin A injection under electromyographic guidance for treatment of spasmodic dysphonia.
TLDR
It is demonstrated that the electromyography signal is a reliable prognostic indicator in terms of efficacy, and that patients' subjective opinion is a valid indicator of treatment success and future treatment strategy.
Management of Adductor Spasmodic Dysphonia
TLDR
A diagnostic approach for spasmodic dysphonia is outlined and the effectiveness of type II thyroplasty for AdSD is reported on with perceptual analysis through use of the Voice Handicap Index-10(VHI-10).
Spasmodic Dysphonia.
TLDR
Diagnosis is challenging as SD can coexist with other neuromuscular disorders with voice symptoms, and the condition can involve the larynx alone, or it can be associated with a spectrum of head and neck dystonias such as blepharospasm.
Relationship of laryngeal botulinum toxin dosage to patient age, vitality, and socioeconomic issues.

TLDR
The presence of movement disorders followed almost all cases of spasmodic dysphonia, including orofacial dystonias, essential tremor and spastic paraparesis.
How Useful are Localization Techniques in Botulinum Toxin Injections for Dystonia and Spasticity Indications
TLDR
The widely applied clinical indications for dystonia and spasticity have been specifically chosen as their focus and an attempt was made to summarize in one place the available evidence.

Outcomes Assessment following Treatment of Spasmodic Dysphonia with Botulinum Toxin
TLDR
Outcome measures justify the continued treatment of SD with BTX, which significantly lessened the patients' perception of dysphonia and improved their social functioning and their perception of their mental health.
Historical approaches to the treatment of Adductor-Type Spasmodic Dysphonia (ADSD): review and tutorial.
TLDR
The most current research hints at the potential benefits of a multi-faceted approach to symptom management, combining behavioral with pharmacological treatments for ADSD.
Outcomes of botulinum toxin treatment for patients with spasmodic dysphonia.
TLDR
Spasmodic dysphonia has a significant impact on patients' perception of quality of life as measured by the Voice Handicap Index, and significant improvements in all 3 subscale scores and the total score occur after treatment with botulinum toxin.
Spasmodic dysphonia: therapeutic options
TLDR
Bilateral selective denervation of the laryngeal adductors with reinnervation by the ansa cervicalis holds promise for an excellent long-term treatment for adductor spasmodic dysphonia.
Spasmodic Dysphonia: Botulinum Toxin Injection after Recurrent Nerve Surgery
TLDR
Botulinum toxin injections were an effective treatment of post-surgical symptom recurrence in adductor spasmodic dysphonia and symptom return was associated with thyroarytenoid innervation after recurrent nerve surgery.

TLDR
Botulinum toxin A injection of the laryngeal hyperfunctional muscles has been found over the past 12 years to be the treatment of choice to control the dystonic symptoms in most patients with spasmodic dysphonia.
Selective Laryngeal Adductor Denervationreinnervation: A New Surgical Treatment for Adductor Spasmodic Dysphonia
TLDR
In this new procedure, the adductor branch of the recurrent laryngeal nerve is selectively denervated bilaterally, and its distal nerve stumps are reinnervated with branches of the ansa cervicalis nerve.
Botulinum Toxin Management of Adductor Spasmodic Dysphonia after Failed Recurrent Laryngeal Nerve Section
TLDR
It is concluded that BTX-A is effective in the treatment of adductor spasmodic dysphonia in patients who have had recurrent nerve section, however, nerve section may adversely affect perceived voice function and may make botulinum toxin therapy less satisfactory.
Effects of Botulinum Toxin on Pathophysiology in Spasmodic Dysphonia
TLDR
The results suggest that changes in the central pathophysiology are responsible for changes in speech symptoms following treatment in persons with adductor spasmodic dysphonia.
