Laryngeal Stenosis: Symptoms and Treatment.
Contact Us
Laryngeal stenosis is a condition that affects the larynx, the tube-like structure at the front of the neck that houses the vocal cords and plays a crucial role in sound production and protecting the airways.
What is laryngeal stenosis?
It is characterized by an abnormal narrowing of the larynx. This narrowing can impede the passage of air to the lungs and affect the function of the vocal cords.
Laryngeal stenosis can be congenital, meaning present from birth, or acquired due to injuries, inflammation, or scarring of the larynx.
Symptoms of laryngeal stenosis
Symptoms can vary in severity and may include:
Difficulty breathing:
which can lead to episodes of breathlessness.
Changes in voice:
The voice may become hoarse, rough, or nearly unintelligible due to the restricted airflow through the larynx.
Persistent cough:
Irritation of the vocal cords and larynx can lead to chronic coughing.
Fatigue when speaking:
Speaking may require significant effort due to the obstruction in the larynx.
Causes of laryngeal stenosis
The causes of laryngeal stenosis can be diverse and may include:
- Traumatic injuries: Neck injuries, such as car accidents or falls, can damage the larynx and lead to stenosis.
- Intubation: Endotracheal intubation, a medical procedure involving the insertion of a tube into the trachea, can cause inflammation and scarring in the larynx.
- Inflammatory issues: Conditions like gastroesophageal reflux disease or chronic laryngitis can cause inflammation in the larynx, which over time may lead to stenosis.
Diagnostic process
The diagnosis of laryngeal stenosis typically involves:
- Medical history: The doctor collects information about symptoms, their duration, and any history of trauma or medical procedures.
- Physical examination: Physical examinations of the neck and larynx can be conducted to evaluate the obstruction.
- Imaging tests: Imaging tests like computed tomography or magnetic resonance imaging can provide detailed information about the structure of the larynx.
- Endoscopy: Laryngoscopy is a technique that uses an endoscope to directly observe the larynx and confirm the diagnosis.
Treatments for laryngeal stenosis
Some treatment options include:
- Laryngeal dilation: This procedure involves the use of a special instrument to widen the narrowed area in the larynx.
- Surgery: In severe cases, surgery may be performed to remove the obstruction or repair the larynx.
- Voice therapy: Voice therapy with a speech therapist can help improve vocal quality in mild cases.
Risk Factors
Risk factors associated with laryngeal stenosis may include:
- Trauma: A history of neck injuries or previous surgery on the larynx increases the risk.
- Inflammatory diseases: Chronic exposure to irritants or inflammatory conditions can increase the risk of developing stenosis.
Don't ignore the symptoms of laryngeal stenosis.
