    Abstract:
    Spasmodic dysphonia is a focal form of laryngeal dystonia that causes unintended contractions of vocal folds with speech interruptions and affecting the voice quality. There are adductor (82%), abductor (36%), mixed (1%) types and reported by Blitzer--respiratory adductor type with paradoxical vocal fold movement and stidor. As an example of diagnostic and therapeutic difficulties in spasmodic dysphonia and its multidisciplinary approach with needed cooperation of many specialists we presented patient with adductor spasmodic dysphonia. In stroboscopic evaluation there were observed glottic overclosure and hyperaduction in supraglotic stuctures (sphincteric). During diagnostic procedures there was made acoustic analysis by digital spectrograph (by KAY Elmetrics Company). IV degree of hoarsness and voice breaks were observed in sonogram. In multidimentional analysis there were deviations of the frequency, amplitude, noise, tremor and voice break parameters. Treatment included regular speech therapy, relaxation- and psychotherapy. The results of treatment were very instable because every stress-related problem released symptoms. Botulinum toxin injections into thyro-arytenoid muscle which had made before our hospitalisation were also not succeeding. Because of lack of etiologic factor and plenty diseases that can mimic spasmodic dysphonia, close communication between many specialists is needed.
