title: Myotonic dystrophy type 1 (DM1) presenting with laryngeal stridor and vocal fold paresis.
abstract: Myotonic dystrophy type 1 (DM1) is the most common inherited muscle disorder and may present in numerous ways due to characteristic multisystem involvement. We report a 47-year-old man who presented with an 8-year history of slowly progressive dyspnea and episodic stridor. The laryngeal paresis was documented with videostroboscopy and laryngeal electromyography, and treated with tracheostomy and antimyotonia agents.
