Spasmodic Dysphonia and Vocal Tremor
2021Spasmodic dysphonia is a focal laryngeal dystonia affecting the voice. Several subtypes exist, presenting different diagnostic and treatment challenges. Vocal tremor is a separate disorder characterized by involuntary oscillation of the laryngeal and pharyngeal musculature, resulting in modulation of pitch and loudness.

Spasmodic Dysphonia Subsequent to Head Trauma
Archives of Otolaryngology - Head and Neck Surgery, 1987Spasmodic dysphonia (SD) is a low-incidence voice disorder of unknown origin. A subgroup of seven patients with SD from our larger pool of 70 report vocal symptoms subsequent to head injury. This article is a case report of the neurodiagnostic findings, including computed tomography, magnetic resonance imaging, auditory brain-stem response, brain ...

Botulinum Toxin for Relief of Spasmodic Dysphonia
Archives of Otolaryngology - Head and Neck Surgery, 1987To the Editor .—The preliminary report by Miller and coworkers, 1 and two other presentations at our national meetings, have demonstrated the temporary effectiveness of botulinum toxin (BT) for the relief of spasmodic dysphonia. The use of a myoneural blocking agent such as BT is logical, and has the advantage that different adductor muscles can be ...

Differential diagnosis of muscle tension dysphonia and spasmodic dysphonia
Current Opinion in Otolaryngology & Head & Neck Surgery, 2010Muscle tension dysphonia (MTD) can mimic the voice features of adductor spasmodic dysphonia (ADSD) leading to diagnostic confusion. Researchers have begun to compare characteristics of MTD and ADSD to determine whether there are markers which reliably distinguish the two disorders and lead to improved differential diagnosis.Differences between MTD and ...

Perceptual-acoustic relationships in spasmodic dysphonia
Journal of Voice, 1993Perceptual ratings were obtained from voice samples of 19 patients with adductor spasmodic dysphonia before and 1 week after unilateral treatment with Botulinum toxin. Five experienced listeners judged samples of sustained phonation using a seven-point equal-interval scale.

BOTULINUM TOXIN FOR THE TREATMENT OF SPASMODIC DYSPHONIA
Otolaryngologic Clinics of North America, 2000Spasmodic dysphonia is a focal laryngeal dystonia. Laryngeal dystonia presents as: adductor spasmodic dysphonia with the characteristic strain-strangle voice; abductor spasmodic dysphonia with hypophonia and breathy breaks in connected speech; and adductor respiratory dystonia with paradoxical vocal fold motion and intermittent stridor.

Brainstem Conduction Abnormalities in Spasmodic Dysphonia
Annals of Otology, Rhinology & Laryngology, 1983Twelve spasmodic dysphonia patients were evaluated by three different auditory brainstem response parameters; 75 % were abnormal. Three of the 12 had prolonged wave I-V interpeak latency. Seven had pathologic wave V latency shifts at a high stimulus rate. Amplitude ratios were normal for all subjects.
