In recent decades there has been and increasing awareness of the role of the criopharyngeus muscle in disorder of swallowing. Failure of temporal incoordination of cricopharyngeal relaxation during pharyngeal contraction results in dysphagia. Aspiration with bronchopulmonary infection and progressive malnutrition are frequently present. Dysfunction of the cricopharyngeal muscle is a manifestation of numerous disorders affecting any level of the neuromuscular axis to the cervical esophagus. The most common cause is cerebrovascular disease. We experienced the three cases of cricopharyneal achalasia and report these cases with the review of literature.

Keywords: Cricopharyngeal achalasia.
