[A case of laryngeal adductor dystonia treated with transcutaneous injections of botulinum toxin].

We present a case of 47-year old patient with a rare form of focal dystonia restricted to laryngeal adductors with blepharospasm. Apart from typical symptoms of blepharospasm, the patient had severe problems with articulation in the form of harsh voice, frequently interrupted speech and the sound coming out with a great effort. We applied a transcutaneous botulin toxin therapy to this patient. The toxin was given into thyroarytenoid muscle in transcutaneous injections under control of EMG. Successful clinical effect was achieved with the dose of 80 U of the botulin toxin (Dysport) and lasted 6 months. The treatment was repeated, and the patient has not presented the symptoms of the disease since then for 10 months. We confirm that the botuline toxin transcutaneous injections represent a save and effective treatment for laryngeal adductor dystonia.
