What is inspiratory stridor?

Generally, an inspiratory stridor suggests airway obstruction above the glottis while an expiratory stridor is indicative of obstruction in the lower trachea. A biphasic stridor suggests a glottic or subglottic lesion. Laryngeal lesions often result in voice changes.

What does stridor sound like in a baby?

The noisy breathing often sounds like a high-pitched wheezing or whistling, and may be audible when a child inhales, exhales, or both. Stridor is usually the result of a narrowed or partially blocked airway, the passage that connects the mouth to the lungs.

When should I be concerned about stridor?

Stridor usually indicates an obstruction or narrowing in the upper airway, outside of the chest cavity. “Stridor in infants, particularly without any associated illness, should always be checked out by a physician,” Walsh says. A number of conditions can block or narrow the upper airway and cause stridor.

Do babies grow out of stridor?

Laryngomalacia is a birth defect characterized by the softening of the tissues above the larynx (voice box). Babies with this condition usually have stridor (noisy or high-pitched breathing). Generally, laryngomalacia goes away on its own by the time your baby is one year old.

Does tummy time help with laryngomalacia?

For infants that have feeding difficulties, thickened feeding or positional feeding can help ease symptoms. Your healthcare provider may also recommend that you place your baby on their tummy to sleep. This helps keep the tissue from obstructing the airway.

When does laryngomalacia need surgery?

Approximately 10% of patients with severe congenital laryngomalacia require surgical intervention because of failure to thrive, significantly elevated carbon dioxide or hypoxemia, severe obstructive sleep apnea, pulmonary hypertension, or cor pulmonale.

How is stridor produced in laryngomalacia?

The high-pitched noise of stridor is created by airflow through an area of obstruction. In laryngomalacia the supraglottic structures collapse into the airway during the inspiratory phase of respiration which produces inspiratory stridor.

What is the most common cause of stridor?

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.

What is laryngomalacia and how does it occur?
