“…Some patients also experience episodes of airway obstruction which wake them from sleep. It is unclear whether this represents laryngospasm secondary to possible laryngopharyngeal reflux (LPR) or possible hypersensitivity of the laryngeal afferent sensory pathways [43][44][45]. Untreated OSA is thought to be a possible risk factor for PVFMD, although the relationship is unclear [43,46].…”

The larynx plays an important role in assessment and treatment of adult sleep apnoea. Laryngeal afferent sensory pathways play a critical role in reflexes controlling airway patency during sleep. Airway obstruction at the laryngeal level should be considered and assessed especially in OSA patients nonresponsive to standard therapies. Isolated laryngeal airway obstruction is rare but identification of specific conditions is important as they are amenable to appropriate treatments. OSA can also affect normal laryngeal function. People with OSA exhibit higher levels of laryngeal inflammation, laryngopharyngeal reflux, and chronic cough. Treatment with continuous positive airway pressure has a potential role in improving laryngeal symptomatology in these cases.

“…PVFMD is more common than previously recognized and should be considered when dyspnea is present without pulmonary disease or is out of proportion to the degree of coexistent pulmonary disease 1. As Chevalier Jackson (an American pioneer in laryngology) often quoted, “not all that wheezes is asthma.”2 PVFMD is often misdiagnosed as asthma, which leads to the inappropriate choice of treatment options for subjects with this condition 3.…”

“…As Chevalier Jackson (an American pioneer in laryngology) often quoted, “not all that wheezes is asthma.”2 PVFMD is often misdiagnosed as asthma, which leads to the inappropriate choice of treatment options for subjects with this condition 3. Undiagnosed PVFMD has been shown to lead to immense health care costs where there are reports of unnecessary intubations and tracheostomies performed in these cases1 and increased asthma medication usage 4. One study found that 42.4% of patients with PVFMD were misdiagnosed with asthma for, on average, 9 years 4.…”

The forgotten cause of stridor in the emergency department

Paradoxical Vocal Fold Movement Disorder is where the larynx exhibits paradoxical vocal cords closure during respiration, creating partial airway obstruction. Causes of vocal fold movement disorder are multifactorial, and patients describe tightness of throat, difficulty getting air in, have stridor, and do not respond to inhalers. We propose using transnasal laryngoscopy examination, which will show narrowing of vocal cords on inspiration, and The Pittsburgh Vocal Cord Dysfunction Index with a cutoff score of ≥4 to distinguish vocal fold movement disorder from asthma and other causes of stridor. Management of paradoxical vocal fold movement disorder involves a combination of pharmacological, psychological, psychiatric, and speech training. Paradoxical vocal fold movement disorder is a very treatable cause of stridor, so long as it is identified and other organic causes are excluded.

“…[1] The patients generally have obstructive airway complaints such as stridor, wheezing, dyspnea and cough while breathing. [1,2] As it is a rarely seen functional disorder, generally misdiagnoses and treatments are made. [2,3] PVCM is basically diagnosed by adduction of vocal cords in inspirium and observation of a rectangular posterior glottic fissure during laryngoscopic examination during an attack.…”
