Laryngeal atresia is one of the rarest congenital malformations.(1) This anomaly is one of the etiologic factors causing congenital laryngeal high airway obstruction syndrome. According to Smith and Bain,(2) laryngeal atresia is classified into 3 types. Type 1 is complete atresia of the larynx with a combination of midline fusion of arytenoid cartilage and intrinsic muscles. Infraglottic obstruction is called type 2 and is characterized by dome-shaped cricoid cartilage obstructing the lumen. Type 3 is occlusion of the anterior fibrous membrane and fusion of the arytenoid cartilage at the level of the vocal processes.(2) Types 1 and 2 are mostly accompanied by other congenital defects.(3)
