Laryngomalacia is the most common congenital anomaly of the larynx. In the majority of cases, the stridor resolves spontaneously by the age of two years. However, laryngomalacia is not a totally benign condition, and some patients have required tracheotomy. In this paper, a case of laryngomalacia with inward collapse of the arytenoids and aryepiglottic folds was reported. Using microsurgical instruments, the mucosa over the arytenoids and aryepiglottic folds was resected. The postoperative

We successfully treated a case of severe congenital subglottic stenosis with an open trough method. After the stenotic tissue of the subglottis was excised through the laryngotracheal fissure, advancement skin flaps from the adjacent neck were fashioned and sutured to the posterior mucosa remnant to form an open trough. A silicone tube stent was inserted into the trough to keep the laryngotracheal cavity wide open. Three months later, the anterior wall of the larynx and trachea was reconstructed with a composite auricular graft. To date, respiratory improvement has been maintained for six years.
