Cricopharyngeal myotomy
Cricopharyngeal Myotomy
Cricopharyngeal myotomy (/kriːkoʊfəˈrɪndʒiəl maɪˈɒtəmi/) is a surgical procedure performed to treat dysphagia, a condition characterized by difficulty in swallowing.
Etymology
The term 'cricopharyngeal myotomy' is derived from three Greek words: 'krikos' meaning ring, 'pharynx' referring to the throat, and 'myotomy' meaning muscle cutting.
Procedure
In a cricopharyngeal myotomy, the cricopharyngeus muscle, which forms a ring around the top of the esophagus, is cut to relax the muscle and improve swallowing. This procedure is typically performed when the cricopharyngeus muscle fails to relax during swallowing, a condition known as cricopharyngeal dysfunction.
