Tracheal Stenosis: Symptoms, Causes and Treatment Options

What Is Tracheal Stenosis?

Tracheal stenosis is a condition in which the trachea, or windpipe, becomes abnormally narrow. This narrowing restricts airflow into and out of the lungs, potentially causing breathing difficulties and affecting daily activities.

Early diagnosis and appropriate treatment can help improve breathing and quality of life.

What Causes Tracheal Stenosis?

Tracheal stenosis can develop due to several factors, including:

•     Prolonged intubation or a previous tracheostomy
•     Scar tissue following airway injury
•     Previous airway surgery
•     Inflammation or certain medical conditions
•     Rarely, a growth or tumor affecting the airway

Identifying the underlying cause is important for planning appropriate treatment.

Common Symptoms of Tracheal Stenosis

Symptoms may develop gradually and can include:

•     Shortness of breath, particularly during physical activity
•     Noisy breathing or wheezing
•     Persistent cough
•     Difficulty breathing during exercise
•     Recurrent respiratory symptoms

Severe airway narrowing can cause significant breathing distress and requires urgent medical attention.

How Is Tracheal Stenosis Diagnosed?

Diagnosis may involve a medical history review, physical examination, CT imaging of the airway and bronchoscopy. These investigations help assess the location, severity and possible cause of the narrowing.

What Are the Treatment Options?

Treatment depends on the severity and location of the stenosis. Options may include endoscopic airway dilation, selected airway procedures or tracheal reconstruction surgery. Some patients require a combination of treatments.
