[Electrostimulation of laryngeal muscles with fluctuating currents in the treatment of patients with unilateral laryngeal paralysis].

Intralaryngeal electrostimulation of the laryngeal muscles with fluctuating currents with simultaneous mobilization of the arytenoid cartilage and paralysed vocal cord were used in 42 patients with unilateral laryngeal paralysis. The treatment was combined with phonopedic lessons. The control group consisted of 32 patients receiving standard electrostimulation with diadynamic currents. The effect was evaluated by changes in vocal acoustic parameters and stroboscopic parameters. In patients with paramedian fixation of the vocal cords voice improvement was obtained irrespective of electrostimulation type. For patients with intermedian and lateral fixation of the vocal cords more effective was intralaryngeal electrostimulation with fluctuating currents. A good therapeutic effect was achieved in patients with dislocation of the arytenoid cartilage.
