Sumario:Laryngeal dystonia or spasmodic dysphonia is characterized by involuntary and innapropiate spasms of vocal muscles, having the adductor type as the most common one. It is chacterized by strain-strangled voice with pitch breaks. Diagnosis is made by means of videolaryngostroboscopic exam. The treatment of choice is done with botulinum toxin directly injected in the muscles responsible for the mismatched movement. The aim of this study is to report on an adductor-type dysphonia patient and to discuss the advantages and observations about this treatment reported in the literature.
