Botulinum toxin treatment of false vocal folds in adductor spasmodic dysphonia: Functional outcomes.
OBJECTIVES/HYPOTHESIS Supraglottic injection of botulinum toxin (Botox) has been described as an effective treatment for adductor spasmodic dysphonia (ADSD). Anecdotal evidence suggests that the patients have little to no breathiness after injection, but no formal longitudinal studies have been carried out to date. The purpose of this study was to examine the voice outcomes in patients with ADS...
متن کاملFunctional reinnervation of vocal folds after selective laryngeal adductor denervation-reinnervation surgery for spasmodic dysphonia.
Selective laryngeal adductor denervation-reinnervation surgery (SLAD-R) offers a viable surgical alternative for patients with adductor spasmodic dysphonia refractory to botulinum toxin injections. SLAD-R selectively denervates the symptomatic thyroarytenoid muscle by dividing the distal adductor branch of the recurrent laryngeal nerve (RLN), and preventing reinnervation, by the proximal RLN an...
متن کاملAbnormal structure-function relationship in spasmodic dysphonia.
Spasmodic dysphonia (SD) is a primary focal dystonia characterized by involuntary spasms in the laryngeal muscles during speech production. Although recent studies have found abnormal brain function and white matter organization in SD, the extent of gray matter alterations, their structure-function relationships, and correlations with symptoms remain unknown. We compared gray matter volume (GMV...
متن کاملVocal aging and adductor spasmodic dysphonia: Response to botulinum toxin injection
Aging of the larynx is characterized by involutional changes which alter its biomechanical and neural properties and create a biological environment that is different from younger counterparts. Illustrative anatomical examples are presented. This natural, non-disease process appears to set conditions which may influence the effectiveness of botulinum toxin injection and our expectations for its...
متن کاملAdductor spasmodic dysphonia: standard evaluation of symptoms and severity.
Description and quantification of the symptoms of adductor spasmodic dysphonia often reflect the clinician's knowledge of the disorder, ideas about the cause of the disorder, and personal experience. No reliable instrument that identifies and quantifies the spectrum of perceptual symptoms has been available. Therefore, we developed a standardized measure called the Unified Spasmodic Dysphonia R...
