Objectives/Hypothesis Obstructive sleep apnea syndrome (OSAS) is a chronic condition, characterized by recurrent episodes of upper airway collapse during sleep, which affects up to 5% of adults in the Western population. The muscle tone of the human body ordinarily relaxes during sleep, thus causing airway obstruction and leading to sleep apnea. We report a case of a 68‐years old male in which dystonic closure of the larynx during sleep caused OSAS. The sleep endoscopy was crucial in establishing the diagnosis of laryngeal dystonia. A botulinum toxin injection in the vocal cord improved the OSAS. These findings define a novel sleep‐related breathing disorder.
