Stridor is a loud, harsh, high pitched respiratory sound. It may start as low-pitched 'croaking' and progress to high-pitched 'crowing' on more vigorous respiration.

It is usually heard on inspiration due to partial obstruction of the airway usually extrathoracic - that is, in the trachea, larynx or pharynx. Stridor can occur on expiration in severe upper airway obstruction but usually indicates tracheal or bronchial obstruction intrathoracic.

What is stridor? Stridor is noisy breathing that occurs due to obstructed air flow through a narrowed airway. Stridor breathing is not in and of itself a diagnosis, but rather is a symptom or sign that points to a specific airway disorder. The timing and the sound of your child's noisy breathing provides clues to the type of airway disorder:. Any process that causes airway narrowing can cause stridor. With infants, stridor usually indicates a congenital disorder problem that your child is born with , including laryngomalacia , vocal cord paralysis or subglottic stenosis.

If your toddler or older child develops stridor, it may occur as a result of an infection such as croup or papillomatosis. In rare circumstances, stridor can occur secondary to trauma or foreign body aspiration. The evaluation of stridor begins with a history and physical examination of your child.

Important history will include questions regarding the onset, duration and progression of stridor as well as associated feeding or voice disturbances.
