Question
What are the causes of neonatal laryngomalacia?
Answer
Neonatal laryngomalacia is caused by the airflow passing through a narrow segment of the airway during breathing, which can be triggered by a variety of different causes leading to airway narrowing. Common causes include: 1. Congenital pure laryngomalacia; 2. Acquired traumatic laryngomalacia (birth trauma, laryngeal edema, acquired subglottic stenosis); 3. Neurogenic laryngomalacia (vocal cord palsy, laryngeal neuromuscular dystonia)
