Vocal Cord Dysfunction
What is Vocal Cord Dysfunction?
Vocal cord dysfunction (VCD), also known as laryngeal dysfunction or a paradoxical vocal cord movement disorder, is a condition characterized by the abnormal closure of the vocal cords while breathing.
Causes of Vocal Cord Dysfunction
Vocal cord dysfunction may be caused by:
- Upper respiratory infection
- Post-nasal drip
- Inhaling toxic fumes, tobacco smoke, or other strong irritants
- An emotional or stressful episode
- Exercise
- Laryngopharyngeal reflux disease (LPRD)
- Gastroesophageal reflux disease (GERD)
- Severe depression
Symptoms of Vocal Cord Dysfunction
Signs and symptoms of vocal cord dysfunction include:
- Difficulty breathing
- Wheezing
- Throat tightness
- Hoarse voice
- Voice changes
- Frequent coughing or throat-clearing
- Noisy breathing
- Shortness of breath
Diagnosis of Vocal Cord Dysfunction
The doctor will review your symptoms and medical history and evaluate your breathing pattern and any voice changes while inhaling and exhaling. If you experience voice changes or hoarseness, your doctor may order further tests such as spirometry or laryngoscopy.
- Spirometry: This a breathing test conducted to measure the quantity and speed of airflow while breathing. The procedure uses a spirometer that determines the airflow rate while breathing.
- Laryngoscopy: This a process used to study the vocal cords while breathing by using a miniature camera attached to a flexible tube that provides pictures of the vocal cords while breathing.
Treatment for Vocal Cord Dysfunction
VCD is quite different from other breathing-related disorders since medications are generally not used to treat it.
The main treatment protocol for VCD involves learning techniques to help control your vocal cords. A specially trained speech therapist or psychologist is best suited in this area. Your therapist will show you various methods to relax your throat muscles to better control your vocal cords.
You must continue your therapy even while the symptoms associated with the disorder recede, as the regular and continuous practice is required to control the vocal cords and prevent the condition from worsening.
If an emotional crisis caused by stress or trauma is the cause of the VCD, you may also be treated with relaxation techniques, biofeedback, and psychotherapy in order to develop better control over your emotions to help with managing VCD.
In cases of asthma-related VCD, your treatment will address the asthma symptoms. Once your breathing is under control, you may be asked to practice techniques that help you improve your vocal cord condition. It is important to treat your asthma first as VCD learning techniques may fail if your asthma is not under control.
