Abstract

Spasmodic dysphonia is defined as a focal laryngeal disorder characterized by dystonic spasms of the vocal cord during speech. We described a case of a 22-year-old male patient who presented complaining of idiopathic difficulty swallowing that suddenly developed 6 months ago. The patient also reported pharyngolaryngeal pain, throat discomfort, dyspnea, and voice change. Because laryngoscopy found no specific problems, an electrodiagnostic study and videofluoroscopic swallowing study (VFSS) were performed to find the cause of dysphagia. The VFSS revealed continuous twitch-like involuntary movement of the laryngeal muscle around the vocal folds. Then, he was diagnosed with spasmodic dysphonia by VFSS, auditory-perceptual voice analysis, and physical examination. So, we report the first case of spasmodic dysphonia accompanied with difficulty swallowing that was confirmed by VFSS.
