Softening of the cartilages of the trachea. [tracheo- + G. malakia, softness]

* * *

tra·cheo·ma·la·cia (tra″ke-o-mə-laґshə) softening of the tracheal cartilages, often as a congenital condition in infants or in patients of any age after prolonged intubation, and usually accompanied by a barking cough and expiratory stridor or wheezing; nearby organs such as the esophagus or aorta may compress the trachea and cause apnea.
