AbstractBotulinum toxin injection is an effective treatment for spasmodic dysphonia. There are ethical difficulties in performing a controlled placebo trial to assess the effectiveness of this treatment. This paper shows a significantly decreased clinical response following technically poor injections given to patients who respond well to good quality injections.

AbstractBotulinum toxin injection is now recognized as an effective treatment for spasmodic torticollis. Complications of this increasingly popular method of treatment include mild and transient dysphagia, with or without dysphonia, lasting up to four weeks. Two cases of paralysis of vocal cord contralateral to the injected sternomastoid have also been reported. A case of severe dysphagia lasting six weeks associated with ipsilateral vocal cord palsy following botulinum toxin injection is presented. The probable mechanism for these complications is discussed.

Introduction. This study prospectively evaluates and compares the treatment efficacy of botulinum toxin injection under electromyography guidance (EMG group) and percutaneous botulinum toxin injection under flexible fiberscopic guidance (fiberscopy group).Methods. Thirty patients with adductor spasmodic dysphonia (ADSD), who had never received treatment, were randomly allocated into EMG- or fiberscopy-guided botulinum toxin injections between March 2008 and February 2010. We assessed acoustic and aerodynamic voice parameters, and the voice handicap index (VHI) before injection and at 1, 3, and 6 months after injection.Results. The mean total dosage of botulinum toxin was similar for both groups: 1.7 ± 0.5 U for the EMG group and 1.8 ± 0.4 U for the fiberscopy group (P>0.05). There were no significant differences in outcomes between the two groups in either the duration of effectiveness or complications such as breathy voice and aspiration.Conclusion. Botulinum toxin injection under fiberscopic guidance is a viable alternative to EMG-guided botulinum toxin injection for the treatment of adductor spasmodic dysphonia when EMG equipment is unavailable.
