The present study examined acoustic, aerodynamic, and videostroboscopic measures of voice production following BOTOX injections in 4 patients with Adductor Spasmodic Dysphonia. Videostroboscopic measures showed a return to some normal aspects of vocal fold vibration 1 month post-injection. Several subjects exhibited suggested meaningful differences both one week and one month post-injection for acoustic and aerodynamic measures; however, results were highly variable and often did not bring the subjects' values into the normal range.
