Spastic dysphonia is a severe vocal disability in which a person speaks with excessively adducted vocal cords. The resulting weak phonation sounds tight, as if he were being strangled, and has also been described as laryngeal stutter. It is often accompanied by face and neck grimaces. In the past it has been regarded as psychoneurotic in origin and treated with speech therapy and psychotherapy with disappointing results. Because of laboratory and clinical observation that recurrent nerve… 
Recurrent Laryngeal Nerve Section for Spasmodic Dysphonia
TLDR
Twenty-two patients with documented spasmodic dysphonia present for at least one year have been managed at the Cleveland Clinic since Dedo's report in 1976, and none of them had any improvement with conventional voice therapy and were subjected to recurrent laryngeal nerve section.
Implantation of a Recurrent Laryngeal Nerve Stimulator for the Treatment of Spastic Dysphonia
TLDR
This study directly stimulated the recurrent laryngeal nerve and vagus nerve in a dog without change in cardiorespiratory status and a Medtronic peripheral nerve stimulator was implanted in a patient with abductor spastic dysphonia, resulting in improvement in her voice.
Treatment of Spastic Dysphonia without Nerve Section
TLDR
This experimental study was designed to create an animal model for an implantable nerve stimulator to be used on a long-term basis and to implant nerve stimulators into spastic dysphonia patients who respond well to percutaneous stimulation.
A Treatment for Spastic Dysphonia
TLDR
A surgical method to resect only the terminal branch of the recurrent laryngeal nerve distributed in the thyroarytenoid muscle, resulting in reduction of spastic factors in the voice is designed.

This presentation compares the preoperative voice recordings and the latest follow-up voice recordings, made 5 to 14 years postoperatively, of the first 300 patients with various degrees of spastic
Spasmodic dysphonia combined with insufficient glottic closure by phonation
TLDR
The case history of a patient who suffered from symptoms deriving from two different origins, where the patient's voice was spasmodic dysphonia-like interrupted and pressed, and an incomplete closure of the vocal cords during phonation in the middle third was present.
Recurrent Laryngeal Nerve Avulsion for Treatment of Spastic Dysphonia
TLDR
The technique of neural avulsion removing the distal nerve up to its insertion into the laryngeal muscles is described, and neural regrowth, which is just one of the possible mechanisms for recurrence of spastic dysphonia, should be prevented by this surgical modification.
Selective Section of the Recurrent Laryngeal Nerve for the Treatment of Spastic Dysphonia: An Experimental Study and Preliminary Clinical Report
TLDR
It is theorized that selective nerve section may decrease the likelihood of the long-term failure that has been seen with complete nerve section by preventing medial fixation of the paralyzed vocal cord.

TLDR
Patients with spastic dysphonia were studied to identify the characteristics of patients benefiting from recurrent laryngeal nerve (RLN) surgery, and two subtypes ofSpastic dysphonic patients are proposed.

Intracordal Injection of Teflon® in the Treatment of 135 Patients with Dysphonia
TLDR
Although some patients with hoarseness after surgical or blunt trauma were improved, the results were not as consistent, and pure laryngeal paralysis was virtually always improved, usually to a normal phonatory voice.

130 cases of spastic dysphonia are reviewed with special emphasis on the etiology of the disorder, which points strongly to a psychogenic origin in the vast majority of cases.
