Congenital Stridor

Practice Essentials

Stridor is a clinical sign characterized by monophonic, audible breath sounds (noisy breathing) that usually originates from the extrathoracic airways. The presence of stridor indicates a partial obstruction of the upper airways, glottis, or trachea. The pitch of the stridor is determined by the degree of airway obstruction and the velocity of the airflow; the loudness and tone of the sound also varies by the specific cause. Congenital stridor presents at birth or within the first few weeks (4-6) of life.
