Laryngomalacia.

Laryngomalacia is the most common cause of stridor in neonates. It typically presents with inspiratory stridor and is often associated with feeding problems. Severe cases present with stridor, apnea, significant respiratory distress, and failure to thrive. Most patients are managed conservatively and can expect to see symptom resolution by 12-24 months of age. About 10% of patients require surgical treatment for their symptoms. Supraglottoplasty is the surgical technique of choice. Results of this surgery are excellent, and severe complications, such as supraglottic stenosis and aspiration, are uncommon. Supraglottoplasty is less effective in patients with significant comorbidities such as neurologic conditions and syndromes.
