Airway Stenosis

Airway stenosis (airway narrowing) is a narrowing of the airway caused by malignant and benign tumors, congenital abnormalities, airway injury, endotracheal intubation, tracheostomy, or autoimmune diseases – though sometimes there’s no obvious cause.

Why Choose UT Southwestern for Airway Stenosis Care?

Airway stenosis is named according to the location of the narrowing along the airway from the larynx or voice box (laryngeal stenosis, posterior glottic stenosis, or subglottic stenosis) to the trachea (tracheal stenosis) and bronchi (bronchial stenosis).

We feature advanced imaging technology to create a 3-D reconstruction of the area of stenosis for better definition and treatment planning. We work closely with UT Southwestern pulmonologists, thoracic surgeons, oncologists, and speech pathologists to deliver multidisciplinary and comprehensive care.

How Is Airway Stenosis Diagnosed?

If we suspect that you have airway stenosis, we will conduct a physical examination and order studies to confirm the diagnosis.

Tests, procedures, and advanced imaging modalities provide the necessary information to evaluate and diagnose airway stenosis. These can include:

• Laryngoscopy and tracheoscopy to examine the larynx (voice box) and trachea (windpipe)
• Bronchoscopy, endobronchial ultrasound (EBUS), and other interventional lung procedures
• Chest X-rays (radiographs)
• Cardiac imaging studies
• Computed tomography (CT) with 3-D reconstructions
• Magnetic resonance imaging (MRI)
• Pulmonary laboratory studies
• Ultrasound

How Is Airway Stenosis Treated?

Our team of highly skilled otolaryngologists, interventional pulmonologists, and thoracic surgeons uses a variety of state-of-the-art techniques, including tracheal reconstruction, to preserve the airway (larynx, trachea, and bronchi) and voice.

Treatments include:

• Airway stenting: Use of a hollow tube to hold the trachea open
• Bronchoscopic or balloon dilation (expansion) of the trachea: To allow better airflow
• Laser excision: Use of a laser to destroy abnormal tissue causing the stenosis or obstruction
• Removal or resection and reconstruction of the narrow portion of the trachea: The damaged portion of the airway is removed and the remaining ends are joined together
• Steroid injections into the region of narrowing (stenosis); takes place in the clinic
