About PVFM PVFM happens when your vocal folds close when they should open. When you take a breath, your vocal folds should open to let air through to your lungs. With PVFM, your vocal folds close part way or all the way. This can make it hard to breathe. PVFM does not happen all the time.
Ear nose and throat doctors refer to this disorder as “paradoxical vocal fold motion disorder” or PVFMD. Lung doctors (pulmonologists) often refer to this disorder as “vocal cord dysfunction” or VCD. These terms are interchangeable and refer to the same disorder.
VCD is sometimes confused with asthma because some of the symptoms are similar. In asthma, the airways (bronchial tubes) tighten, making breathing difficult. With VCD, the vocal cord muscles tighten, which also makes breathing difficult. Unlike asthma, VCD is not an allergic response starting in the immune system.
Laryngospasm, a subtype of vocal cord dysfunction, is a brief involuntary spasm of the vocal cords that often produces aphonia and acute respiratory distress. Laryngospasm is a common complication of anesthesia.
Paradoxical Vocal Fold Motion Disorder Symptoms, Signs, and Diagnosis. Patients with PVFM often report symptoms of increased difficulty with inhalation, feeling as if the throat is tightening or closing off, and a sound (stridor) with inhalation.
Speech therapy is usually the first treatment for PVCD. Often it is enough to correct the disorder. Other professionals such as psychologists may also be involved in the treatment. Speech therapy focuses on decreasing tension in the larynx by helping patients focus on exhaling rather than inhaling.
Laryngospasm is a frightening condition that happens when your vocal cords suddenly seize up, making breathing more difficult. This rare phenomenon is often a symptom of an underlying condition. If you've had recurring laryngospasms, you should see your healthcare provider to find out what's causing them.
Vocal cord dysfunction (also known as exercise-induced laryngeal obstruction) is a common condition characterized by the throat inexplicably closing during rigorous exercise. It can dramatically increase breathing difficulty, diminish performance and often causes panic in those who experience it.
Yes, some asthma inhalers, especially Advair, can cause irritation or inflammation of the vocal cords, he said.
Laryngospasm (luh-RING-go-spaz-um) is a transient and reversible spasm of the vocal cords that temporarily makes it difficult to speak or breathe. The vocal cords are two fibrous bands inside the voice box (larynx) at the top of the windpipe (trachea).
Several studies have established that paroxysmal laryngospasm is often secondary to laryngopharyngeal reflux, a variant of gastroesophageal reflux disease (GERD). Paroxysmal laryngospasm is often misdiagnosed as asthma, hysterical stridor, obstructive sleep apnea, paroxysmal nocturnal dyspnea, and other conditions [7].
Attempt manual ventilation while continuing to apply continuous positive airway pressure (CPAP). Attempt to break the laryngospasm by applying painful inward and anterior pressure at 'Larson's point' bilaterally while performing a jaw thrust.
What are the symptoms of vocal cord dysfunction?Throat or chest tightness.Noisy inhalation.Difficulty getting air "in"Feeling of throat closing.Feeling of being "strangled"Intermittent shortness of breath.Chronic cough.Voice change/Inability to speak.
Vocal cord dysfunction is treated by an ear, nose, and throat doctor (ENT, also called an otolaryngologist), a pulmonologist, and a speech therapist. They work together to help the child learn to relax the vocal cords while breathing. Treatment for vocal cord dysfunction may also include: practicing breathing exercises.
Stress, posttraumatic stress disorder (PTSD), anxiety, depression and panic attacks have all been linked to episodes of vocal cord dysfunction. Anxiety is more likely to trigger an episode in kids and teenagers than adults.
Emotional responses like stress and anxiety can trigger laryngospasm. It's your body's physical response to an intense emotion that you're feeling. Sleep-related laryngospasm. Some people experience laryngospasm in their sleep and wake up gasping for air.

VCD defined as "a paradoxical movement of the vocal cords' - with a hyperfunctional laryngeal reflex which results in adduction (coming together) of the vocal cords with resultant airflow limitation (Porsbjerg 2017, Kenn 2012)
Somatoform disorders are psychological difficulties with symptoms of a physical disorder unexplained by a medical condition. Conversion or somatization disorder (more common) unconsciously produced deficit in motor or sensory functioning, always preceded by a psychological stressor; females>males.
Attacks typically do not respond to medical therapy targetted to reactive airway disease (beta antagonists)
As per Forrest et al (Forrest 2012) Although PVCM (paradoxical vocal cord motion) may be a psychological disorder, there are different forms which they divided into "primary, or psychological, and secondary" - with the secondary form consists of medical disorders divided into irritable larynx syndrome and neurologic disorders.
Severe airway obstruction as in the case depicted below of a laryngeal dystonia may be associated with life-threatening airway obstruction and may warrant tracheotomy
Paradoxical Vocal Fold Movement (PVFM) Paradoxical vocal fold movement, or PVFM, makes it hard to breathe or talk. It does not happen all of the time but can cause serious problems when it does happen. Children and adults can have PVFM. Speech-language pathologists, or SLPs, can help.
The SLP can teach you exercises that help keep your vocal folds open when you breathe and when PVFM happens . See information for professionals on ASHA’s Practice Portal pages on Voice Disorders and Aerodigestive Disorders.
Vocal cord dysfunction or paradoxical vocal fold motion (PVFM) is an episodic condition that results when vocal cord movement is dysfunctional. We open our vocal cords when we breathe, and we close them when we speak, sing, swallow or lift heavy items. Vocal cord dysfunction describes what is occurring when our vocal cords close when we intended them to open to breathe. This incorrect vocal cord motion causes an abnormal narrowing of the voice box. The voice box narrowing leaves only a small opening for air to flow through the vocal cords, which can result in a sensation of difficulty moving air into or out of the lungs.
Therapy generally requires two to six 60-minute sessions . These sessions aim to:
The voice box narrowing leaves only a small opening for air to flow through the vocal cords, which can result in a sensation of difficulty moving air into or out of the lungs. People who suffer PVFM episodes often have a very sensitive or reactive airway. Common triggers include: Acid reflux. Exercise.
Cough or fumes. Vocal cord dysfunction is sometimes misdiagnosed as asthma because the symptoms and triggers for PVFM and asthma can be similar. The difference between PVFM and asthma is that if you have asthma, medicines that open your breathing tubes (bronchodilators such as albuterol) will improve your breathing.
Vocal cord paralysis is usually diagnosed by an otolaryngologist (NIDCD, 1999). Noting the symptoms the patient has experienced, the otolaryngologist will ask how and when the voice problems started in order to help determine their cause. Next, the otolaryngologist listens carefully to the patient's voice to identify breathiness or harshness. Then, using an endoscope, the otolaryngologist looks directly into the throat at the vocal cords. A speech-language pathologist may also use an acoustic spectrograph, an instrument that measures voice frequency and clarity, to study the patient's voice and document its strengths and weaknesses.
Treating people who have 2 paralyzed vocal cords may involve performing a surgical procedure called a tracheotomy to help breathing (NIDCD, 1999). In a tracheotomy, an incision is made in the front of the patient's neck and a breathing tube (tracheotomy tube) is inserted through a hole, called a stoma, into the trachea. Rather than breathing through the nose and mouth, the patient now breathes through the tube. Following surgery, the patient may need therapy with a speech-language pathologist to learn how to care for the breathing tube properly and how to reuse the voice.
If nothing is done to change vocal abuse habits, vocal cord nodules can last a lifetime, and may even recur after surgical removal. With proper voice training with a certified therapist, nodules can disappear with 6 to 10 voice therapy sessions over 6 to 12 weeks.
Patients are taught to be succinct when speaking, to avoid any loud use of the voice, to keep phone calls brief and to avoid all non-speech voice use (throat clearing, coughing, "voiced" sneezing, crying, "voiced" laughing, and odd sound-effects).
Treatment for nodules that do not resolve with voice therapy involves surgical removal of the nodules at direct laryngoscopy and correction of the underlying voice abuse. Vocal nodules in children usually regress with voice therapy alone.
Vocal cord nodules (singer's nodules) are small, hard, callus like growths that usually appear singly on the vocal cord (Merck, 1997). Nodules consist of condensations of hyaline connective tissue in the lamina propria at the junction of the anterior 1/3 and posterior 2/3 of the free edges of the true vocal cords. Vocal cord polyps are small, soft growths that usually appear singly on a vocal cord. They are most often caused by vocal abuse or long-term exposure to irritants, such as chemical fumes or cigarette smoke.
Surgery involves adding bulk to the paralyzed vocal cord or changing its position (NIDCD, 1999). To add bulk, an otolaryngologist injects a substance, commonly Teflon, into the paralyzed cord. Other substances currently used are collagen, silicone, and body fat. The added bulk reduces the space between the vocal cords so the non-paralyzed cord can make closer contact with the paralyzed cord and thus improve the voice.
Paradoxical vocal fold motion (PVFM), also called paradoxical vocal cord dysfunction, is a breathing disorder characterised by approximation rather than abduction/opening of the vocal folds during inspiration. This can result in upper-airway obstruction and stridor. [1]#N#Andrianopoulos MV, Gallivan GJ, Gallivan KH.

Paradoxical vocal fold motion (PVFM) is a disorder often misdiagnosed in children presenting with shortness of breath and stridor. In infants, little is known about the clinical course and best approach for treatment of PVFM. This retrospective study assesses the approach to treatment and outcomes for infants with PVFM.
Paradoxical vocal fold motion (PVFM), also known as vocal cord dysfunction (VCD), is the untimely adduction of vocal cords during inspiration resulting in obstruction at the level of the glottis. The width of the rima glottides, the space between vocal folds, is determined largely by vocal fold movement thereby determining air flow through the glottic aperture. During inspiration, the posterior cricoarytenoid muscle contracts resulting in abduction of vocal folds and widening of the rima glottides, while during expiration contracture of the lateral cricoarytenoid results in adduction of vocal folds and narrowing of the rima glottides. In PVFM, there is aberrant adduction of vocal folds during the act of inspiration [ 1, 2 ]. On visualization of the vocal cords, there is a characteristic, yet uncommon, finding of adduction of the anterior two-thirds with a diamond-shaped gap or “chink” in the posterior aspect of the vocal folds [ 3, 4 ]. Clinically, this manifests as resulting dyspnea and noisy breathing in the form of stridor.
PVFM can be challenging to diagnose in the infant population. PVFM resolves uneventfully with reflux treatment, however, it is unknown whether reflux treatment is essential or if PVFM would spontaneously resolve. The rarity of infantile PVFM mandates formal evaluation and monitoring by a pediatric otolaryngologist.
