LCs are rare congenital anomalies consisting of a midline defect along the posterior portion of the larynx and trachea as well as the anterior portion of the esophagus, leaving a communication between these structures of varying lengths. Pattersson carried out the first successful repair of a LC in 1955 . Benjamin and Inglis classified LCs into four types. Type I is a supraglottic interarytenoid cleft. Type II extends into (but not through) the posterior cricoid lamina. Type III extends through the cricoid and can involve the cervical trachea. Type IV extends below the thoracic inlet .
