What Is Laryngotracheomalacia?

Laryngotracheomalacia is a common cause of chronic, congenital stridor, a sound caused by abnormal air passage to the lungs, according to National Center for Biotechnology Information. This is often caused by an obstruction, and it can be intermittent.

This clinical symptom is often determined by performing upper and lower endoscopies while the patient is under anesthesia. The blockage can be located anywhere in the extrathoracic or intrathoracic airway. When found, the patient is generally admitted to an intensive care unit until further diagnosis and treatment can be performed. Diagnosis often entails both physical and radiological examinations. Stridor is common in about one out of every 10 infants, reports NCBI.
