Tracheomalacia

What is Tracheomalacia?

Tracheomalacia in a newborn occurs when the cartilage in the windpipe, or trachea, has not developed properly. Instead of being rigid, the walls of the trachea are floppy, resulting in breathing difficulties soon after birth. Babies born with tracheomalacia may have other congenital abnormalities such as heart defects, developmental delay, or gastroesophageal reflux. Also, aspiration pneumonia can occur from inhaling food. 

Symptoms 

  • Breathing noises that may change with position and improve during sleep 
  •  Breathing problems that get worse with coughing, crying, feeding, or upper respiratory infections 
  • High-pitched or rattling breathing 

 

Diagnosis

A physical examination confirms the symptoms. A chest X-ray may show narrowing of the trachea when breathing in. A procedure called a larngoscopy, which allows the otolaryngologist to see the airway structure, provides a definitive diagnosis. Other tests may include: 

  • Airway fluoroscopy 
  • Barium swallow 
  • Bronchoscopy, a camera down the throat to see the airways and lungs 
  • CT scan 
  • Lung function tests 
  • Magnetic resonance imaging (MRI) 

Treatment

Most infants respond well to humidified air, careful feedings, and antibiotics for infections. Babies with tracheomalacia must be closely monitored when they have respiratory infections. Often, the symptoms of tracheomalacia improve as the infant grows. Rarely, surgery is needed. 

Prognosis

Congenital tracheomalacia generally goes away on its own by the age of 18-24 months. As the tracheal cartilage gets stronger and the trachea grows, the noisy respirations and breathing difficulties gradually stop. 

Tracheomalacia is diagnosed and treated by physicians, nurses and other clinical staff in the Divisions of  Neonatal-Perinatal Medicine  and Otolaryngology  at Hopkins Children’s.
