Tracheomalacia is a rare condition characterised by collapse of the trachea during respiration. The condition is seen most often in infants and young children. Mild cases can be managed expectantly; however, severe cases can be associated with life-threatening cyanotic attacks and intervention to stabilise the airway is invariably necessary. Most commonly this involves an aortopexy to suspend the anterior wall of the trachea but other options include endoluminal or extraluminal stenting, long-term positive pressure ventilation and tracheostomy. Although tracheomalacia resolves spontaneously in most infants within the first few years of life, severe tracheomalacia is associated with significant morbidity and mortality that should not be underestimated.
