Tracheomalacia

Abstract

Tracheomalacia is excessive collapsibility of the trachea, typically during expiration. Congenital forms are associated with severe symptoms. Milder forms often present after the neonatal period. Adult malacia is mostly associated with chronic obstructive pulmonary disease. Functional bronchoscopy is still not standardized. Dynamic airway CT is a promising tool for noninvasive diagnosis. Bronchoscopy and stent insertion lead to significant improvement, but with a high complication rate. Surgical lateropexia, tracheal resection, and surgical external stabilization are options. Tracheoplasty seems to be the best choice for selected cases of adult malacia. The most commonly performed surgery in children is aortopexy.
