Stridor is a high-pitched, wheezing sound caused by disrupted airflow. Stridor may also refer to a harsh, vibrating noise when breathing, caused by a narrowed or blocked airway. It is most noticeable during inhalation, but can also occur during exhalation.
Causes[edit]
Stridor is usually caused by narrowing or blockage of the airways. This can be due to a variety of conditions, including:
- Congenital abnormalities: These are problems that are present at birth, such as laryngomalacia, tracheomalacia, or vascular rings.
- Infections: Infections can cause inflammation and swelling in the airways, leading to stridor. Examples include croup, epiglottitis, and bacterial tracheitis.
- Foreign body aspiration: This occurs when a foreign object is inhaled into the airways, causing blockage and stridor.
- Tumors: Both benign and malignant tumors in the airways can cause stridor.
- Trauma: Injury to the airways, such as from a burn or inhalation of a harmful substance, can cause stridor.
Diagnosis[edit]
The diagnosis of stridor involves a thorough medical history and physical examination. Additional tests may include:
- X-ray: This can show if there is a blockage in the airways.
- CT scan: This provides a more detailed image of the airways and can help identify tumors or other abnormalities.
- Laryngoscopy: This involves using a small, flexible tube with a light and camera to examine the throat and voice box.
- Pulmonary function tests: These tests measure how well the lungs are working and can help determine the severity of the stridor.
Treatment[edit]
Treatment for stridor depends on the underlying cause. Options may include:
- Medication: Drugs to reduce inflammation and open the airways can be helpful.
- Surgery: If the stridor is caused by a structural problem, such as a tumor or congenital abnormality, surgery may be necessary.
- Speech therapy: This can help improve breathing techniques and reduce symptoms in some cases.
