Differential diagnosis of adductor spasmodic dysphonia and muscle tension dysphonia using acoustic parameters
Objective:The study aimed at differentiating Adductor Spasmodic Dysphonia (ADSD) from Muscle Tension Dysphonia (MTD) using acoustic measurements . Method: Perceptual as well as acoustic analysis of the voice was done on 12 patients of Adductor Spasmodic dysphonics and Muscle tension dysphonics each. The age of these patients ranged between 30 to 64 years . Results: Adductor spasmodic dysphonics...
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...

OBJECTIVE To evaluate the long-term aerodynamic, acoustic, and electromyographic effects of serial botulinum toxin (BT) injections in patients with adductor spasmodic dysphonia. DESIGN Two-year, nonrandomized, controlled, before-after study. SETTING Ambulatory care clinic at a single academic medical center. PATIENTS A convenience sample of 91 patients with adductor spasmodic dysphonia ev...
متن کاملBrainstem pathology in spasmodic dysphonia.
Spasmodic dysphonia (SD) is a primary focal dystonia of unknown pathophysiology, characterized by involuntary spasms in the laryngeal muscles during speech production. We examined two rare cases of postmortem brainstem tissue from SD patients compared to four controls. In the SD patients, small clusters of inflammation were found in the reticular formation surrounding solitary tract, spinal tri...
متن کاملTreatment of adductor spasmodic dysphonia with selective laryngeal adductor denervation and reinnervation surgery.
Spasmodic dysphonia (SD) is a voice disorder characterized by abnormal intermittent spasms of intralaryngeal muscles that result in voice breaks during speech. In the adductor variant of spasmodic dysphonia (ADSD), spasms of the adductor muscles cause strangled voice breaks and a strained-strangled voice quality. In the abductor variant (ABSD), spasms of the posterior cricoarytenoid muscle (PCA...
