Signs and Symptoms
Tracheal Stenosis: Signs and Symptoms
Tracheal stenosis, a condition where the airway narrows, can cause a range of symptoms that affect an individual's quality of life. The signs and symptoms of tracheal stenosis can vary in severity and may not always be immediately apparent.
Common Symptoms:
- Noisy breathing (stridor) [3]
- Recurring pneumonia [3]
- Wheezing [3][5][6]
- Cyanosis (blue-spells) [3]
- Shortness of breath that is gradually worsening [4][5]
- Respiratory sounds (stridor) which may sound like wheezing [4]
- Coughing [5][8]
- Shortness of breath [5][6][7][8]
- Wheezing [5][6][7]
- Difficulty breathing [7][8]
Other Possible Symptoms:
- Feeding issues in newborns, such as difficulty feeding or swallowing [8]
- Asthma that is not responsive to medication [5]
- Persistent throat clearing or cough [6]
- Hoarseness [6]
It's essential to seek emergency care if you or your child are experiencing any of these symptoms. Tracheal stenosis can be a life-threatening condition, and prompt medical attention is crucial.

Diagnostic Tests
Diagnostic Tests for Tracheal Stenosis
Tracheal stenosis, a narrowing or constriction of the trachea, can be diagnosed using various tests to confirm the condition and determine its severity. Here are some of the diagnostic tests used to diagnose tracheal stenosis:
- Bronchoscopy: Considered the "Gold Standard" for diagnosing tracheal stenosis, bronchoscopy directly visualizes the trachea and is essential in characterizing the stenosis [8]. It involves inserting a flexible tube with a camera and light on the end through the mouth or nose to visualize the airways.
- Endoscopic procedures: In addition to bronchoscopy, other endoscopic procedures such as microlaryngoscopy and bronchoscopy may be used to diagnose tracheal stenosis [2]. These procedures involve using a small telescope to look in the upper and lower airway for signs of narrowing.
- Imaging procedures: Imaging tests such as chest X-rays, computed tomography (CT) scans, and magnetic resonance imaging (MRI) can help identify blockages or fluids creating pressure in the trachea [7]. A CT scan with 3-D reconstruction is also used to diagnose tracheal stenosis [6].
- Pulmonary Function Test: This test measures how much air you can inhale and exhale, which can indicate respiratory function problems related to tracheal stenosis [4].
- Biopsy: A small sample of tracheal or bronchial tissue is removed through a bronchoscope for examination under a microscope to establish a diagnosis [3].
These diagnostic tests are essential in fully diagnosing and characterizing tracheal stenosis, which can help determine the best course of treatment.

Treatment
Tracheal stenosis, also known as tracheal narrowing, can be treated with various methods, including drug treatment. However, it's essential to note that medication is usually not the primary treatment for this condition.
- Corticosteroids: These medications can help reduce inflammation and swelling in the airway, which may alleviate symptoms of tracheal stenosis. However, their effectiveness in treating the underlying narrowing of the trachea is limited [3].
- Bronchodilators: These drugs can help relax the muscles around the airways, making it easier to breathe. While they may provide temporary relief from respiratory symptoms, they do not address the underlying cause of tracheal stenosis [11].
Other treatment options
While drug treatment may be used in conjunction with other therapies, it is often not sufficient on its own to treat tracheal stenosis effectively.
- Surgery: Tracheal resection and reconstruction are common surgical procedures for treating tracheal stenosis. These operations involve removing the narrowed section of the trachea and reconnecting the upper and lower sections [2].
- Stenting: This procedure involves inserting a small tube or stent into the narrowed area to keep it open and improve airflow [6].
Treatment approach
The treatment plan for tracheal stenosis is typically created by an otolaryngologist, who will consider various factors, including the severity of the narrowing, its location, and any underlying conditions that may be contributing to the stenosis.
- Minimally invasive techniques: Some treatments, such as laser surgery or bronchoscopic dilation, can be performed using minimally invasive methods [11][12].

Differential Diagnosis
Differential Diagnosis of Tracheal Stenosis
Tracheal stenosis, a narrowing of the tracheal lumen, can be caused by various iatrogenic, inflammatory, infectious, and neoplastic processes [8]. The differential diagnosis of tracheal stenosis includes:
- Subglottic stenosis: A stricture or narrowing of the subglottic region, which is more frequent in patients with early age of onset [13].
- Laryngomalacia: A condition characterized by soft and pliable cartilage in the larynx, leading to partial airway obstruction.
- Congenital cysts: Abnormal growths present at birth that can compress the trachea.
- Vocal cord paralysis: A condition where the vocal cords are unable to move properly, causing breathing difficulties.
- Hypocalcemic tetany: A rare condition caused by low calcium levels in the blood, leading to muscle cramps and spasms.
- Extrinsic compression of the trachea: Compression of the trachea by vascular rings or mediastinal masses.
- Tracheobronchial stenosis: A narrowing of the trachea and bronchi caused by various conditions such as tumors, inflammation, or trauma.
Other Conditions to Consider
In addition to these specific conditions, other factors that may contribute to tracheal stenosis include:
- External injury to the throat
- Benign or malignant tumor pressing on the windpipe
- Certain autoimmune disorders, such as polychondritis, sarcoidosis, and others [5]
Diagnostic Tests
The definitive diagnosis of tracheal stenosis is made by endoscopy. Other diagnostic tests that may be used to confirm the presence of tracheal stenosis include:
- Microlaryngoscopy: A procedure that allows for a detailed examination of the larynx and trachea.
- Bronchoscopy: A procedure that uses a flexible tube with a camera to visualize the airways.

Congenital tracheal stenosis (CTS) is present at birth. A rare and potentially fatal condition, it affects 1 out of every 64,500 babies. Most are diagnosed at birth or within the first few months of life.
