Tracheal stenosis

What is tracheal stenosis?

Tracheal stenosis refers to the narrowing of the trachea, the main breathing tube of the lungs. It may be caused as a result of an injury (known as acquired tracheal stenosis). This narrowing can restrict airflow to the lungs, making breathing difficult. Tracheal stenosis can vary in severity, from mild to life-threatening, and may require medical intervention to manage symptoms and improve quality of life.

What causes tracheal stenosis?

Tracheal stenosis may occur as a birth defect (known as congenital tracheal stenosis), or often there may be no apparent cause found (idiopathic subglottic stenosis). In the case of acquired tracheal stenosis, the trachea narrows as a reaction to an irritation or injury. In the case of congenital tracheal stenosis, abnormalities in the cartilage of the trachea can cause the airway to narrow.

Diagnosing tracheal stenosis can only be done under direct vision with bronchoscopy. Some common symptoms of the condition include wheezing, apnoea, congestion in the chest, and recurring pneumonia. Many people are often misdiagnosed as having asthma for many years before receiving definitive treatment for the stenosis. Children with the condition may experience worsening symptoms when affected by an upper respiratory infection.

Treatment of tracheal stenosis:

Treatment for tracheal stenosis depends on the severity of the condition and its underlying cause. Options may include:

• Medications: In cases where inflammation is the underlying cause, medications such as corticosteroids may help reduce inflammation and alleviate symptoms.
• Airway dilation: This procedure involves using specialised instruments to widen the narrowed portion of the trachea. It can be performed using techniques such as rigid bronchoscopy or balloon dilation.
• Surgery: In severe cases of tracheal stenosis, surgical intervention may be necessary to remove scar tissue, repair the trachea, or reconstruct a portion of the airway. Surgical techniques may include tracheal resection and reconstruction or placement of stents to keep the airway open.
• Tracheostomy: In some cases, a surgical opening in the trachea (tracheostomy) may be necessary to bypass the narrowed portion of the airway and allow for adequate breathing.
• Lifestyle modifications: Avoiding irritants such as tobacco smoke and managing underlying conditions like gastroesophageal reflux disease (GERD) can help prevent the worsening of tracheal stenosis symptoms.
