What Are the Causes of Tracheal Stenosis?
The most common cause of congenital tracheal stenosis is complete tracheal rings.
In most cases, acquired tracheal stenosis develops after birth. Some possible causes include having:
- A breathing tube for a long period of time
- Neck injury
- Mass in the windpipe
Signs and Symptoms
Children with tracheal stenosis may have the following symptoms:
- Shortness of breath during exercise and sometimes at rest
- Noisy breathing or stridor (sounds like a high-pitched squeal)
- Increased effort to breathe, causing sucking in around the ribs and chest (retractions)
- Cough or chest congestion
- Feeling of mucous “stuck” in the airway
- Frequent pneumonia or upper respiratory infections
- Asthma that doesn’t get better with common treatment
- Pauses in breathing (apnea)
- Skin around the mouth/nose or gums look blue
- Choking or difficulty breathing when eating
- Tires easily with eating
The trachea is hard to see and examine in a regular clinic. In order to diagnose tracheal stenosis, the following tests may be used:
- Microlaryngoscopy and bronchoscopy: Your child goes to sleep in the operating room for this procedure. A small telescope is used to look in the upper and lower airway for signs of narrowing.
- CT scan: Doctors may need to get a picture of the inside of the chest to see if the airway is abnormal.
Treatment depends on the severity of your child’s symptoms.
If symptoms are mild, your child may simply need to see the doctor on a regular basis.
Moderate to Severe Symptoms
For moderate or severe symptoms, your child may need surgery to make the airway larger. This will help your child breathe more easily.
In some cases, your doctor may want to do a surgical procedure called a tracheotomy. In this procedure, an opening is made below the level of airway narrowing. This provides your child a safe airway and makes it easier for them to breathe.
Other possible procedures include:
Endoscopic surgery, including balloon dilation of the airway, is used for children with mild to moderate tracheal stenosis. Using a camera and specially designed balloons, narrow areas are divided and / or widened.
Cricotracheal resection is a surgery to remove the narrow portion of the trachea and reattach the healthy ends of the trachea. This surgery may be done in a single stage or multiple steps.
Slide tracheoplasty is a surgery where the trachea is opened in front and back. It is then slid up on itself and reconnected. This makes the trachea shorter, but much wider.
