Screening for tracheomalacia begins with a physical examination to confirm the breathing symptoms. The doctor may order an X-ray to rule out other problems and to show how much the trachea narrows when the child breathes in.
How Is Tracheomalacia Diagnosed?
For a definitive diagnosis of tracheomalacia, the otolaryngologist may perform a larngoscopy. Using a small camera, the doctor views the airway structure and can determine the severity of the condition.
Other tests for tracheomalacia include:
- Airway fluoroscopy using X-rays to create real-time images of breathing
- Barium swallow – drinking barium to enhance X-ray images
- Bronchoscopy – inserting a camera into the throat to view the airways and lungs
- CT (computed tomography) scan to create very detailed images of the throat
- Lung function tests measuring capacity and level of oxygen delivered to the blood
- Magnetic resonance imaging (MRI) to view the trachea while breathing
