Cricopharyngeal dyskinesia is termed complete or incomplete failure of relaxation of the cricopharyngeus muscle and is one of the cause of dysphagia. Reduced maximal distensibility or compliance of cricopharyngeus muscle results in dysphagia, globus sensation, aspiration and repeated pulmonary infection. We experienced a case of cricopharyngeal dyskinesia in a 75-year- old female who complained of dysphagia. She was treated by cricopharyngeal myotomy with improvement in her symptom.
