Vocal Cord Dysfunction: Causes, Symptoms, and Treatment

What kind of doctor treats Vocal Cord Dysfunction?
An allergist/immunologist, a doctor who treats allergies and asthma, often diagnoses vocal cord dysfunction. An ENT doctor (an ear, nose, and throat doctor) or a pulmonologist (a lung doctor) may help too. A direct primary care or concierge doctor can be a first stop for an evaluation and can refer you to a specialist when needed.
What is vocal cord dysfunction?
Vocal cord dysfunction (VCD) is also called paradoxical vocal fold movement (PVFM). It happens when the vocal cords, which are in the voice box, do not open correctly. It is also called inducible laryngeal obstruction (ILO). During an episode, the vocal cords close partly or fully and limit the air that reaches the lungs. Episodes come and go, and they are set off by things like irritants or activities.
VCD is sometimes confused with asthma because some of the symptoms are similar. In asthma, the airways tighten. In VCD, the vocal cord muscles tighten. Unlike asthma, VCD is not an allergic response starting in the immune system.
Symptoms
- Trouble breathing, especially breathing in.
- Throat or neck tightness during episodes.
- Coughing.
- Noisy breathing. Stridor, a high-pitched, harsh sound from a narrowed upper airway, is the most common symptom.
Trouble breathing often goes away quickly when the trigger is removed. Chest tightness may point to asthma instead.
A hoarse voice or voice change may come with an episode. One source lists these as symptoms, but another says a voice change is not itself counted as a symptom.
Causes and who gets it
The exact cause of VCD is not known. Some researchers think the nerves that sense things in the voice box may become too sensitive, which sets off the body's protective reflexes. Certain triggers can bring on an episode.
- Irritants in the air, such as fumes, dust, smoke, pollen, or changes in temperature or humidity.
- Exercise.
- Stress.
- Acid reflux, which is stomach acid coming up into the throat.
- Colds and other upper respiratory infections.
- Singing, laughing, or shouting.
VCD can happen at any age. It appears to be most common in females, and more common from the teen years to young adulthood.
How doctors diagnose it
VCD can be hard to diagnose. It helps to tell your doctor about trouble breathing in, a hoarse voice, or voice changes. Your doctor may order spirometry, a breathing test that measures airflow. A laryngoscopy lets a doctor look at the vocal cords through a camera on a flexible tube. Vocal cords should be open when you breathe in, but in some people with VCD they close instead. Ideally, doctors diagnose it by watching the vocal cords with a camera while a trigger brings on an episode.
VCD can look like asthma, a panic attack, or an allergic reaction with swelling. A team often works together on the diagnosis. The team can include a speech therapist, a lung doctor, an ear, nose, and throat doctor, a primary care provider, an allergist, a psychologist, and a respiratory therapist.
Treatment
Speech therapy is the main treatment. The treatment for VCD is very different from the treatment for asthma. Treatment often includes activities that relax the throat muscles, such as speech therapy and deep breathing techniques. The goal is to teach the vocal cords to open steadily with each breath so the airway stays open. One strategy is respiratory retraining, which uses several breathing techniques.
- Pursed-lip breathing: breathe in slowly through the nose, pucker the lips, and breathe out slowly through the lips.
- Relaxed throat breathing: this trains the vocal cords to stay open during the whole breath.
- Sniff inhalation: sniff in quickly through the nose with the tongue relaxed.
How much therapy you need depends on how bad the symptoms are, how long you have had episodes, and whether another problem such as reflux or anxiety needs treatment. If you have asthma, allergies, or reflux, treating them also helps. Avoiding triggers, such as pollution and strenuous exercise, is also part of care. How well a person does depends on finding the causes and triggers and avoiding them.
When to see a doctor
A doctor should check repeated episodes that are set off by a trigger. VCD is sometimes confused with asthma, so a proper diagnosis is essential. Call 911 or go to the emergency room if you have trouble breathing. Do the same if you faint, or if you have a sudden change in mental state, such as being hard to wake up.
How a direct primary care or concierge doctor fits in
A direct primary care doctor charges a flat monthly fee instead of billing insurance, while a concierge doctor usually charges more and often works alongside insurance. A direct primary care or concierge doctor can go over your history and look at asthma, allergies, and reflux. They can also refer you to a speech therapist or an ear, nose, and throat doctor.
Common questions
Is vocal cord dysfunction the same as asthma?
No, they are different problems that can look alike. In asthma, the airways tighten. In VCD, the vocal cord muscles tighten. Many people have both.
What triggers vocal cord dysfunction?
Common triggers include irritants in the air, exercise, stress, acid reflux, and colds. Singing, laughing, or shouting can also set it off.
How is vocal cord dysfunction treated?
Speech therapy is the main treatment. It teaches breathing skills that relax the throat muscles. Treating asthma, allergies, or reflux also helps if you have them.
Who gets vocal cord dysfunction?
It can happen at any age, but it appears to be most common in females and in teens and young adults.
