Tracheomalacia (Tracheopexy)
Tracheomalacia is a condition in which the trachea (windpipe) is abnormally soft or weak, causing it to collapse during breathing. This can lead to noisy breathing, frequent respiratory infections, difficulty feeding, or episodes of respiratory distress. Tracheomalacia may be congenital (present at birth) or acquired after surgery, infection, or long-term ventilation. In moderate to severe cases, surgery such as tracheopexy is used to support the airway and reduce symptoms.
Causes and Types
Tracheomalacia may be classified as:
- Primary (congenital): Present at birth, often due to underdeveloped tracheal cartilage.
- Secondary (acquired): May result from prolonged intubation, vascular compression, inflammation, or previous surgeries.
It can also occur with other congenital conditions such as esophageal atresia or vascular rings. The severity ranges from mild to life-threatening, depending on the degree of airway collapse.
Symptoms
Children with tracheomalacia often exhibit symptoms such as:
- Noisy breathing (stridor or wheezing)
- Coughing or barking cough
- Difficulty feeding or poor weight gain
- Recurring respiratory infections
- Episodes of cyanosis (turning blue), especially during crying or feeding
Diagnosis
Diagnosis is usually made through a combination of clinical evaluation and airway imaging or endoscopy. The gold standard for diagnosis is bronchoscopy, which allows direct visualization of the trachea and the extent of collapse during breathing.
Treatment
Treatment depends on the severity of the condition:
- Mild cases may resolve on their own over time as the cartilage stiffens with age. These children are monitored and managed supportively.
- Moderate to severe cases may require surgery. One of the most common procedures is anterior or posterior tracheopexy, where the trachea is surgically secured to surrounding tissues to keep the airway open during breathing.
Other surgical options include aortopexy (if vascular structures are compressing the airway) or tracheal reconstruction in complex cases.
Outlook
With proper management, most children improve significantly. Long-term follow-up with a multidisciplinary team—including pediatric surgery, pulmonology, and otolaryngology—is often recommended to monitor airway development, nutrition, and growth.
