Some milder forms of laryngotracheal clefts can be repaired using an endoscopic laryngotracheal cleft repair.

In this procedure either a CO₂ laser or a microlaryngeal scissors instrument is used to freshen the edges in the undeveloped lining of the cleft. Resorbable sutures (sutures that biodegrade in the body) are then used to close the cleft.
