[A case of congenital laryngeal web with subglottic stenosis].

A severe case of congenital laryngeal web with subglottic stenosis was reported. The patient had weak crying after birth and stridor was noticed from one month old. He had tracheostomy at two month old and the incision of the web was attempted under laryngomicrosurgery with CO2 LASER, although the attempt failed due to combined subglottic stenosis. The "trough method" was applied at the age of one year. The web was incised and subglottic granulation including the excessive cartilaginous tissue was removed through a laryngotracheal fissure. A piece of silicone membrane was inserted between the vocal cords preventing from adhesion and a silicone tube stent was also inserted into the subglottic space and trachea to keep the laryngotracheal space open widely. After one month and a half, the silicon membrane and silicon tube were removed and a silicon T-tube was inserted instead of the silicon tube. The anterior wall of the laryngotracheal space was closed using a hinge flap. The patient can vocalize and does not complain of dyspnea at present, one year after the removal of the T-tube.
