“…Some authors contend that voice quality is normal between episodes of PVFM [26][27][28] , whereas Treole et al [6] found endoscopic and stroboscopic evidence of residual laryngeal muscle tension after PVFM attacks and concluded that this could contribute to altered phonatory characteristics in these patients. Specifically Treole et al [6] reported an increased prevalence of lateral ventricular constriction, decreased mucosal wave and decreased lateral amplitude in individuals with PVFM.…”

Voice problems have been reported in chronic cough (CC) and paradoxical vocal fold movement (PVFM), however, there is a lack of a systematic description of voice characteristics in these conditions. This study examined the perceptual voice characteristics of 56 individuals with CC, 8 with PVFM and 55 with both CC and PVFM, compared to 25 people with muscle tension dysphonia (MTD) and 27 healthy controls. There was a high prevalence of abnormal voice quality in the CC and PVFM groups compared with healthy controls. More than one third of participants with CC and PVFM demonstrated strained, rough and/or breathy voices to a moderate or severe degree. The perceptual features in CC and PVFM were similar to those in MTD with greater severity evident in MTD. Possible mechanisms for abnormalities in voice quality include the presence of muscle tension and the frequency of coughing. These results have implications for the identification and management of voice disorders in CC and PVFM and suggest that clinicians should be alert to the incidence of voice abnormalities in these populations.

“…31,43,44 Similar clinical findings between asthma and PVFM may lead to a misdiagnosis of PVFM for asthma and result in unnecessary treatments including prolonged courses of oral steroids, intubation, and tracheotomy. 31,37,45 In PVFM, there is extra thoracic airway obstruction primarily by constriction around the glottal region. This obstruction is usually demonstrated by reduced inspiratory curves on pulmonary function testing and symptomatically, and inspiration is noted to be affected more than expiration.…”

“…Nasendoscopy during a symptomatic attack is considered the gold standard for diagnosing PVFM, 47 as vocal fold adduction during inspiration can be directly observed. 33,34,48,49 In practice, however, it is difficult to access nasendoscopy during symptomatic attacks as they rarely occur in a hospital environment and vocal fold function is often normal during phonation 31,45,50 and symptom-free periods. The diagnosis of PVFM requires exclusion of organic causes of upper airway obstruction including neoplasms, trauma, and vocal fold paralysis 31 and laryngeal dystonia.…”

“…45,49,54 Rothe and Karrer 89 questioned the routine diagnosis of conversion disorder and suggested that some forms of PVFM might be caused by chronic irritation of the larynx. Some authors have proposed classification systems for PVFM that support the presence of psychological issues in only a subgroup of patients rather than an underlying factor in all cases.…”

“…On the one hand, similar laryngoscopic findings and/or symptomatology (e.g. onset/termination of attacks post-exposure, inducers of attacks, causation and patient demographics) have been described with different terms [4,7,14,17,22,28,29,37,[44][45][46], while on the other hand the same nomenclature has been used to describe differing clinical features [47][48][49][50][51][52]. This lack of an international consensus on nomenclature prevents research and expertise from different centres from being matched, pooled or readily utilised by others and effectively hampers progress in the area.…”

ERS/ELS/ACCP 2013 international consensus conference nomenclature on inducible laryngeal obstructions

Individuals reporting episodes of breathing problems caused by re-occurring variable airflow obstructions in the larynx have been described in an increasing number of publications, with more than 40 different terms being used without consensus on definitions. This lack of an international consensus on nomenclature is a serious obstacle for the development of the area, as knowledge from different centres cannot be matched, pooled or readily utilised by others. Thus, an international Task Force has been created, led by the European Respiratory Society/European Laryngological Society/American College of Chest Physicians. This review describes the methods used to reach an international consensus on the subject and the resulting nomenclature, the 2013 international consensus conference nomenclature.
