title: Vocal fold paralysis and progressive cricopharyngeal stenosis reversed by cricopharyngeal myotomy.
abstract: Three infants with progressive upper esophageal stenosis had bilateral vocal fold paralysis. The patients were apparently normal at birth and without neurologic abnormality. Cricopharyngeal myotomy, followed by serial dilatations, relieved esophageal stenosis and restored the swallowing function. Vocal fold mobility, to the authors' surprise, also recovered after myotomy in 2 patients. Vocal paralysis persisted in the first patient encountered, although this case was complicated by longstanding tracheostomy. Decannulation in this case was successful at 4 years only after arytenopexy and cricoid interposition grafting. Direct laryngoscopy findings showed weak abductive motion of 1 vocal fold at 14-year follow-up. Loss of vocal function secondary to constriction by a cricopharyngeal band has been previously undocumented. The potential reversibility of both vocal paralysis and esophageal stenosis by surgical cricopharyngeal myotomy is of significant clinical importance.
