Congenital condition where there is failure of resorption of tissue between the vocal folds, causing varying degrees of airway obstruction. The condition may present at birth or in infancy with respiratory distress, stridor, and an unusual, weak, or absent cry. If obstruction is severe, can be life-threatening and require immediate tracheotomy after birth. Milder cases may present later in life with hoarseness, stridor, wheezing, or dyspnea. Sometimes occurs with associated congenital anomalies of the respiratory tract or cardiac defects. Can also result from injury due to trauma, intubation, or surgical procedure.

May be treated with dissection or laser surgery.
