Scholarcy highlights

  • We describe clinical experiences in the management of three patients with laryngopharyngeal dystonia causing severe breathing problems
  • In contrast to spasmodic dysphonia, which presents with action-induced involuntary spasms of laryngeal muscles during speaking, all three patients showed laryngopharyngeal spasms primarily during respiration
  • In analogy to spasmodic dysphonia we propose the term spasmodic laryngeal dyspnea for this rare condition
  • Localized unilateral botulinum toxin injected into the thyroarytenoid muscle and /or ventricular folds reduced the quantity and quality of spasms and led to a pronounced improvement of breathing problems
