متن کاملVoice Related Quality of Life in Spasmodic Dysphonia : Treatment Effects and Correlation with Voice Assessment
Spasmodic Dysphonia (SD) patients (adductor type) are known to score very high on the Voice Handicap Index (VHI). 28 VHIanalyses were performed in patients diagnosed with spasmodic dysphonia (SD), before and after treatment with botulinum toxin.

متن کاملLongitudinal variations of laryngeal overpressure and voice-related quality of life in spasmodic dysphonia.
OBJECTIVES/HYPOTHESIS Adductor spasmodic dysphonia (AdSD) is a voice disorder characterized by variable symptom severity and voice disability. Those with the disorder experience a wide spectrum of symptom severity over time, resulting in varied degrees of perceived voice disability. This study investigated the longitudinal variability of AdSD, with a focus on auditory-perceptual judgments of a ...
متن کاملCombined-modality treatment of adductor spasmodic dysphonia with botulinum toxin and voice therapy.
A combined-modality treatment program consisting of botulinum toxin injection (Botox) and voice therapy was used to treat 17 subjects diagnosed with adductor spasmodic dysphonia (ADD SD).
