Laryngeal Cleft

Every child has a breathing tube starting at the nose and mouth and extending into the lungs. He or she also has a feeding tube just behind the breathing tube that brings food and liquid to the stomach. If there is a connection at the very top of these two tubes, we call this a laryngeal cleft. If the connection is in the middle of these two tubes, we call this a fistula.

Diagnosis and Treatment

Laryngeal clefts begin at the very top of the two tubes. Imagine a zipper unzipping, and you can understand how deep clefts can be. If the zipper unzips only to the level of the vocal cords, then it is a type 1 cleft.  If the zipper unzips all the way down so there is a connection all the way down the two pipes, this is a type 4 cleft.  

Type 2,3, and 4 clefts require surgical repair so that the child does not continue to aspirate (a condition in which food or liquid is trapped in the lungs) and develop chronic lung problems. Some children with type 1 clefts eventually outgrow them, so if they can managed on thickened feeds and are not getting pneumonia, often we wait until they are 2 or 3 before making a decision whether or not to operate.
