Summary

Spasmodic dysphonia (SD) is a chronic voice disorder which can cause a significant decrease in voice related quality of life with no cure. The most common treatment is botox injections in the larynx, with the effect lasting for about 3 months. The procedure is performed in awake, unsedated conditions therefore patients experience pain which in turn affects the tolerance of the procedure. The investigators seek to study whether applying ice compress immediately before the injection would decrease SD patients' perception of pain with botulinum toxin injection. This will be achieved by giving the patients pain questionnaires to complete 10 minutes after the procedure.
