INTRODUCTION: Nimodipine has been shown to be beneficial for recovery from acute vocal fold paralysis (AVFP) in an animal model. METHODS: prospective, open-label trial of patients with AVFP was performed using nimodipine. Consecutive patients were evaluated and offered nimodipine therapy. RESULTS: Fifty-three patients were considered for treatment with nimodipine. Thirteen did not qualify for inclusion, 5 were lost to follow-up, and 7 had side effects requiring cessation of treatment. Thus 28 patients (30 paralyzed vocal folds) were analyzed. Eighteen of the paralyzed vocal folds experienced recovery of purposeful motion (60%). Historical controls and laryngeal electromyography meta-analysis suggest no more than a 20% recovery rate from AVFP. CONCLUSIONS: This open label study using nimodipine for treatment of AVFP demonstrates tripling of the recovery rate of vocal fold motion compared with historical controls. Further study in a randomized, controlled manner is warranted.
