Why does stridor occur?
Stridor is a noisy or high-pitched sound with breathing. It is usually caused by a blockage or narrowing in your child’s upper airway. Some common causes of stridor in children are infections and defects in the child’s nose, throat, larynx, or trachea that the child was born with.
What is the treatment for stridor?

What is the difference between stridor and wheezing?

Is stridor common?
Stridor is usually the result of a narrowed or partially blocked airway, the passage that connects the mouth to the lungs. The condition is most common in newborns, infants, and toddlers because their airways are narrower—so even a small blockage can interfere with easy breathing. This condition also affects adults.
Where is stridor best heard?

Key points about congenital laryngeal stridor Procedures to diagnose congenital laryngeal stridor may include laryngoscopy or bronchoscopy. In most cases, congenital laryngeal stridor is a harmless condition that goes away on its own.
How do you test stridor?
Careful auscultation of the nose, oropharynx, neck, and chest helps to discern the location of the stridor. In infants, special attention should be paid to craniofacial morphology, patency of the nares, and cutaneous hemangiomas. Growth parameters are helpful, especially in the evaluation of chronic stridor.
Is stridor genetic?
The underlying cause of the condition is unknown. Most cases occur sporadically in people with no family history of the condition.
Is stridor a lung sound?
Less musical sounding than a wheeze, stridor is a high-pitched, turbulent sound that can happen when a child inhales or exhales. Stridor usually indicates an obstruction or narrowing in the upper airway, outside of the chest cavity.
