Abstract
Laryngomalacia is the most common laryngeal malformation that occurs mainly in newborns and children. Symptoms include inspiratory high pitched wheezing, dyspnea, and cyanosis. In most cases, symptoms aggravate until eight months and gradually disappear without any treatment as the patient grows older, but surgical treatment is required in severe cases. The surgical treatment options include epiglottoplasty, supraglottoplasty, aryepiglottoplasty, tracheostomy, and many others performing a resection of excessive mucosa in the larynx. Unlike conventional surgeries, the authors recently treated a case of a two-month-old infant with severe laryngomalacia using a CO2 laser. After performing CO2 laser surgery twice, the patient was cured without complications.
