An Update on Diagnosis of Tracheomalacia in Children

Area of Science:

• Pediatric Pulmonology
• Congenital Airway Disorders
• Neonatal Medicine

Background:

• Congenital tracheomalacia is the most frequent congenital tracheal abnormality, affecting about 1 in 2,100 children.
• It can occur independently or alongside other airway anomalies like laryngomalacia and bronchomalacia.
• Association with abnormal embryonic foregut division, such as esophageal atresia and tracheoesophageal fistula, is common, altering the tracheal cartilage-to-membrane ratio.

Purpose of the Study:

• To provide a comprehensive overview of congenital tracheomalacia.
• To discuss diagnostic methods and management strategies for this condition.

Main Methods:

• Diagnosis relies on clinical history, physical examination, pulmonary function testing, CT, dynamic MRI, and fiberoptic bronchoscopy.
• Tracheobronchography has been used but lacks validation; fluoroscopy offers specificity but limited sensitivity.

Main Results:

• Congenital tracheomalacia frequently resolves spontaneously by the second year of life.
• Symptomatic cases may require interventions such as pharmacotherapy, positive pressure ventilation, or surgical procedures.

Conclusions:

• Congenital tracheomalacia is a common condition with varied presentations and associations.
• While often self-limiting, persistent symptoms necessitate tailored treatment approaches, including medical and surgical options.
