Two cases of severe congenital subglottic stenosis with a glottic web were reported. Congenital defects not related to the larynx were present in both cases. One had interventricular septal defect and cleft palate. The other had a protruding ear.Case 1: A 3-year-old boy with congenital cricoid stenosis and an anterior glottic web was successfully treated by the "trough" method. After a glottic web and exessive cartilaginous tissue of the cricoid were removed through a laryngotracheal fissure, a trough was formed fixing the laryngotracheal mucosa to the skin of the neck. A silicone tube stent was inserted into the trough to keep the laryngotracheal cavity widely opened. After a period of six months, a silicone T-tube was substituted for the tube stent. The T-tube remained in place for two years. During T-tube stenting, palatoplasy was performed uneventfully. The tracheal fistula was closed with a bipedicle skin flap one year after the removal of the T-tube.Case 2: A 6-year-old boy with a congenital glottic web and subglottic stenosis was also treated by the "trough" method. A silicone tube stent had been kept in place for 10 days after operation and was replaced by a stent made of silicone dental impression. After a period of three and half months, the stent was lifted from the trough, and the anterior wall of the larynx and the trachea were reconstructed with a composite auricular graft. Correction of the auricle was performed successfully one month after closure of the trough.
