The injury may be caused by:

• Infections
• Sores (ulcerations) due to foreign objects
• Trauma, such as a gunshot wound or automobile accident

Injuries to the trachea or bronchi also may occur during medical procedures (for example, bronchoscopy and placement of a breathing tube). However, this is very uncommon.

People with trauma who develop a tracheal or bronchial rupture often have other injuries.

Symptoms may include:

• Coughing up blood
• Bubbles of air that can be felt underneath the skin of the chest, neck, arms, and trunk (subcutaneous emphysema)
• Difficulty breathing

The health care provider will perform a physical exam. Close attention will be paid to the symptoms of the rupture.

Tests that may be done include:

• Neck and chest CT scan
• Chest x-ray
• Bronchoscopy
• CT angiography
• Laryngoscopy
• Contrast esophagography and esophagoscopy

People who have had a trauma will need to have their injuries treated. Injuries to the trachea often need to be repaired during surgery. Injuries to the smaller bronchi can sometimes be treated without surgery. A collapsed lung is treated with a chest tube connected to suction, which re-expands the lung.

For people who have breathed a foreign body into the airways, bronchoscopy may be used to take out the object.

Antibiotics are used in people with an infection in the part of the lung around the injury.

The outlook of injury due to trauma depends on the severity of other injuries. Operations to repair these injuries often have good results. The outlook is always better if the person does not have many chronic medical conditions. The outlook is good for people whose tracheal or bronchial disruption is due to causes such as a foreign object, which tend to have a good outcome.

In the months or years after the injury, scarring at the injury site may cause problems, such as narrowing, which require other tests or procedures.

Major complications after surgery for this condition include:

• Infection
• Long-term need of a ventilator
• Narrowing of the airways
• Scarring

Contact your provider if you have:

• Had a major injury to the chest
• Inhaled a foreign body
• Symptoms of a chest infection
• The feeling of air bubbles underneath your skin and trouble breathing
