Laryngomalacia is a congenital condition where the tissues of the larynx (voice box) get soft. This is the most common cause of noisy breathing in infants, because the floppy tissues partially block the airway. The softer tissues can also lead to gastroesophageal reflux disease. In 90 percent of cases, laryngomalacia is not serious and the condition resolves without treatment by 18 to 20 months old. In severe cases, treatment may include medication for GERD or surgery to strengthen or repair the larynx.
