Resumo: A laryngo-tracheo-esophageal cleft (LC) is a congenital malformation characterized by an abnormal, posterior, sagittal communication between the larynx and the pharynx, possibly extending downward between the trachea and the esophagus. The estimated annual incidence of LC is 1/10.000 to 1/20.000 live births, accounting for 0,2 to 1,5% of the congenital malformations of the larynx. These incidence rates may however be underestimated due to difficulty in diagnosing minor forms and a high mortality rate in severe forms. A slightly higher incidence has been reported in boys than in girls. A laryngo-tracheo-esophageal cleft (LC) is a uncommon congenital malformation (1/10.000 - 1/20.000 live births), accounting for 0,5-1,5% of all congenital laryngeal abnormalities. Is characterized by an abnormal, posterior, sagittal communication between the larynx and the pharynx, possibly extending downward between trachea and esophagus. Five types have been described based on the downward extension of the cleft, which typically correlates with the severity of the symptoms. High prevalence of associated anomalies has been reported. Few case reports exists concerning the anesthetic approach to LC surgery. The main concerns for anesthesiologists are the unsecured airway, the difficult ventilation and the high prevalence of associated anomalies.
