Vocal cord dysfunction: an update

Differential diagnosis in paradoxical vocal fold movement (PVFM): An interdisciplinary task

“…She added that her daughter's vocal quality was worse (i.e., hoarse, limited loudness) during communication outside of the home, suggesting additional vocal effort to overcome environmental background noise and communication competition, which is compatible with past reports of dysphonia occurrence between PVFM episodes [32]. Furthermore, her mother reported that the child had experienced GERD and seasonal allergies.…”

“…Because of similar respiratory symptoms, PVFM is often misdiagnosed as asthma, leading to the mismanagement or the disorder [32]. Indeed, acute bronchospasm/asthma-like symptoms may impact accuracy of PVFM diagnosis, leading to unnecessary use of medical consultations and asthma medications.…”

“…Furthermore, her mother reported that the child had experienced GERD and seasonal allergies. The literature shows that there is a high prevalence of these factors (i.e., respiratory struggle during physical exertion, unwanted vocal effort, GERD, and respiratory allergies) in people with PVFM [3][4][5][6]23,32]. Additional indications of instability and effort associated with respiratory-phonatory functions were demonstrated by results of voice acoustic and aerodynamic analysis.…”

“…Because of the various conditions linked to PVFM etiology, ruling out unconfirmed causes is critical for a proper diagnosis [28]. Therefore, suspected cases should receive interactive attention from a team of professionals in related disciplines including minimally the specialties of otolaryngology, pulmonary medicine, allergy, speech-language pathology (SLP), and psychology [19,31,23,32]. Interdisciplinary attention is warranted to avoid misdiagnosis due to similarities with other common disorders, as well as unnecessary utilization of medical approaches and potential delay in the application of proper treatment.…”

Vocal Cord Dysfunction With Acute Respiratory Failure that Required Repeated Intubation

“…Ayşegül Tomruk Erdem, 1 Figen Atalay, 2 Fikret Çınar, 3 Müge Meltem Tor 2 Vokal kord disfonksiyonu, laringeal wheezing ya da laringeal astım olarak da bilinen bozukluk, vokal kordların inspiryum süresince paradoksal olarak kapanıp, obstrüktif hava yolu semptomlarına yol açması ile karakterizedir. Mekanizma tam olarak bilinmemekle birlikte psikojenik faktörlerin ön planda sorumlu olduğu düşünülmektedir.…”
