Abstract

Introduction: Spasmodic dysphonia is a focal dystonia characterized by involuntary dysrhythmic contractions of the musculature of the vocal cord, resulting in a voice with spasmodic contractions that alter the speech rhythm and the patient's communication capacity. Methods: We present a series of 113 patients diagnosed with adductor spasmodic dysphonia with ages between 18 and 65 years. We will perform an acoustic analysis of the voice before and after the treatment with botulinum toxin. Results: We observed a normalization of all parameters in the acoustic analysis after treatment with botulinum toxin. Conclusion: The infiltration of botulinum toxin in the vocal cords is an effective treatment in adductor spasmodic dysphonia and the acoustic analysis of the voice is a good method to verify it
