Larynogomalacia is both the most common congenital laryngeal anomaly and the most frequent cause of stridor in infants. The majority of cases resolve spontaneously. In approximately 10% of these infants, the laryngomalacia is severe and requires surgical intervention. Our experience with 15 children who underwent supraglottoplasty is reported. In most cases, their airway problems and associated symptoms have been resolved after surgery. The symptoms and signs, surgical methods and complications, and prognosis of laryngomalacia are discussed.
