Tracheomalacia

Tracheomalacia describes a generalized or localized weakness of the trachea that results in excessive narrowing of the tracheal lumen during expiration or whenever intrathoracic pressure increases. Severe forms of tracheomalacia are characterized by life-threatening apneic spells, inability to extubate the airways, and episodic pneumonia. Aortopexy has proved to be an effective method of treatment for most of these conditions when seen in children. When aortopexy fails to prevent tracheal obstruction, a support applied to the external circumference of the trachea can be useful to prevent airway collapse.
