Abstract:
Cricopharyngeal spasm and Zenker's diverticulum represent disorders of the pharyngoesophageal junction for which a unifying theory of etiology has yet to be established. There is, however, a large body of evidence that supports an association with gastroesophageal reflux. Cricopharyngeal myotomy is the key to successful management of both disorders. Newer transoral endoscopic techniques of management have a lower overall morbidity than traditional open approaches in appropriately selected patients and are therefore gaining popularity as the preferred method of treatment.
