How Rare Is It?

What Is It Overview Types How Rare?

Not As Rare As You Might Think

Laryngeal cleft is commonly reported to occur in 1 out of every 10,000 - 20,000 live births.

However, that statistic doesn’t present the full story.

That estimate comes from research conducted before 1970 and is only accurate for severe clefts (types 3 and 4).

More recent research has shown that mild clefts (types 1 and 2) are far more common than originally thought.

In fact, mild laryngeal clefts have been found in up to 7.6% of children with chronic respiratory symptoms who undergo airway evaluation under anesthesia.*

Incidence

Up to 7.6% of children with chronic respiratory symptoms who undergo a DLB/ML&B*

Past Research

1 in every 10,000 to 20,000 live births

More research is needed to determine the true incidence of laryngeal clefts.
