Understanding Stridor: Causes, Symptoms, and Treatment Options

Stridor is a rare but serious condition that affects the voice box (larynx) and can cause difficulty breathing, hoarseness, and other symptoms. It occurs when the vocal cords become paralyzed or weakened, leading to abnormal movement of the vocal folds during breathing. This can cause the airway to become narrow or blocked, making it difficult to breathe properly.
Stridor is often seen in children, particularly those with neurological conditions such as cerebral palsy or Down syndrome. However, it can also occur in adults, especially those who have had a stroke or other brain injury.
The symptoms of stridor can vary depending on the severity of the condition, but may include:
Hoarseness or abnormal voice
Difficulty breathing or shortness of breath
Noisy or labored breathing
Grunting or stridorous sounds during breathing
Cyanosis (blue tinge to the skin)
In severe cases, stridor can lead to respiratory failure and other complications. Treatment for stridor usually involves addressing any underlying conditions that may be contributing to the condition, such as a neurological disorder or a blockage in the airway. In some cases, surgery may be necessary to correct any anatomical abnormalities or to remove a blockage.
In addition to these medical treatments, speech therapy and other voice exercises may also be helpful in improving vocal function and reducing symptoms of stridor.
