Current management of laryngeal and laryngotracheoesophageal clefts

Laryngeal and laryngotracheoesophageal clefts (L-LTEC) are uncommon anomalies in neonates that cause significant morbidity secondary to aspiration, pneumonia, and respiratory distress. Other anomalies of development, such as esophageal atresia and tracheoesophageal fistula (EA-TEF), are observed in 20% of patients with L-LTEC and often confuse the radiographic and clinical picture. Repair of L-LTEC depends on the length and location of the cleft, associated anomalies, and concurrent systemic illness. For type I L-LTEC, endoscopic repair occasionally is possible with microsurgical instrumentation. With types II to IV L-LTEC, an open approach must be used. Tracheotomy is a universal requirement, often for extended periods of time. Reported here is our experience with four cases of L-LTEC managed over the past 7 years at Texas Children's Hospital.
