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 | edit source]

Stridor is usually caused by narrowing or blockage of the airways. This can be due to a variety of conditions, including:

Diagnosis[edit | edit source]

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 | edit source]

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.
