INTRODUCTION: Although dyspnea with exercise in the pediatric population can be multifactorial, the diagnosis of paradoxical vocal fold motion disorder (PVFMD) in this group is not well characterized. The objective of this study is to review the multiple causes of dyspnea with exercise in children, including the prevalence of PVFMD within this study population. METHODS: A retrospective review was conducted of patients seen at a tertiary pediatric hospital for exercise-induced dyspnea suspected to be related to PVFMD between January 2007 and July 2015...

Data, regarding the use of botulinum toxin (BT-A) in laryngeal dyspnea, are scarce, coming from some cases reports in the literature, including Vocal fold paralysis, laryngeal dystonia, vocal cord dysfunction also called paradoxical motion of the vocal fold (PMVF), and post-neuroleptic laryngeal dyskinesia. There is no consensus regarding the muscles and the doses to inject. The aim of this study is to present a retrospective review of patients treated in our ENT Department by BT-A injection in this indication...

Paradoxical vocal fold motion disorder, also commonly termed vocal cord dysfunction, is a poorly understood cause of acute upper airway obstruction. Patients with paradoxical vocal fold motion frequently present to the emergency department (ED) with acute respiratory distress and stridor. Lack of familiarity with this disorder may lead to delayed diagnosis or misdiagnosis and unnecessary intubations or surgical airway procedures. Although long-term management of paradoxical vocal fold motion is well described, there is a paucity of information about acute evaluation and management...

Excessive exercise-induced shortness of breath is a common complaint. For some, exercise-induced bronchoconstriction is the primary cause and for a small minority there may be an alternative organic pathology. However for many, the cause will be simply reaching their physiological limit or be due to a functional form of dysfunctional breathing, neither of which require drug therapy.The physiological limit category includes deconditioned individuals, such as those who have been through intensive care and require rehabilitation, as well as the unfit and the fit competitive athlete who has reached their limit with both of these latter groups requiring explanation and advice...

We describe the case of a 13-year-old girl with paradoxical vocal fold motion (PVFM) who failed to improve with repeated medical treatment, speech therapy and psychotherapy, but was successfully treated with botulinum toxin A (BTX-A) injection to the vocal folds. For delivering the BTX-A we used a channeled fiber-optic laryngoscope under local anesthesia, in an office setting. The patient remained asymptomatic of PVFM for 5 months, was successfully treated again with the same method, and had no important side effects...

Exercise as an important part of life for the health and wellness of children and adults. Inducible laryngeal obstruction (ILO) is a consensus term used to describe a group of disorders previously called vocal cord dysfunction, paradoxical vocal fold motion, and numerous other terms. Exercise-ILO can impair one's ability to exercise, can be confused with asthma, leading to unnecessary prescription of asthma controller and rescue medication, and results in increased healthcare resource utilization including (rarely) emergency care...

OBJECTIVES: Paradoxical vocal fold motion (PVFM) and reverse phonation are characterized by aberrant vocal fold adduction. To date, there have been no studies examining the aerodynamic events during reverse phonation. We present an unusual case of persistent reverse phonation secondary to respiratory distress associated with PVFM. STUDY DESIGN: Case report. METHODS: We present the case of a 42-year-old female with sudden onset of respiratory distress associated with PVFM and persistent reverse phonation...

OBJECTIVES: The objective of this study was to contribute to the discussion of differential diagnosis in paradoxical vocal fold movement (PVFM), a disorder frequently associated with episodes of breathing difficulty and stridor. Because of analogous respiratory symptoms, PVFM is often misdiagnosed as asthma. Additional evidence suggests the association of factors such as respiratory struggle during physical exertion, digestive reflux, and respiratory allergies with PVFM, particularly in athletes and young females...

BACKGROUND: Vocal cord dysfunction (VCD) or paradoxical vocal-fold motion (PVFM) is a functional disorder of the vocal cords that requires multidisciplinary treatment. Besides relaxation techniques, the use of psychological interventions can help treat the underlying psychological co-morbidities. There is currently no literature that examines the effectiveness of psychological interventions for VCD/PVFM. OBJECTIVES: To review the evidence for psychological interventions used for the treatment of patients with VCD/PVFM...

IMPORTANCE: Paradoxical vocal fold motion (PVFM) affects almost 1 million adolescents in the United States. However, to date, no disease-specific objective measure exists to assess symptom severity and response to treatment in adolescents with exercise-induced PVFM. OBJECTIVES: To validate the Dyspnea Index (DI) quality-of-life instrument (previously validated for adults with breathing disorders) in children aged 12 to 18 years with exercise-induced PVFM and to determine the minimum significant DI change corresponding to patient-reported or caregiver-reported improvement or worsening of symptoms...

OBJECTIVES/HYPOTHESIS: Paradoxical vocal fold motion and exercise-induced paradoxical vocal fold motion (EIPVFM) are two related conditions that do not have definitive diagnostic criteria. Much of the EIPVFM literature describes patients with characteristic physiologic findings of severe upper airway obstruction or obvious airflow limitation in the clinical context of exertional dyspnea with audible stridor. The objective of this study was to highlight a group of patients who demonstrate important clinical findings of EIPVFM (exertional dyspnea with audible stridor) without simultaneously definitive physiologic findings (mild glottic adduction and normal flow volume loops)...

OBJECTIVE: Exercise-induced airway obstruction in pediatric patients is a unique phenomenon with multiple potential etiologies. An accurate diagnosis can be challenging to establish in pediatric patients because they are frequently asymptomatic at rest. Exercise stress laryngoscopy (ESL) is a modality by which pediatric patients can be evaluated under physiologic conditions that produce their symptoms. The purpose of this study was to demonstrate (1) the diagnostic effectiveness of pediatric ESL and (2) the ability of ESL to guide treatment for "normal" and post-airway reconstruction patients with exercise intolerance...

We describe an unusual case of paradoxical vocal fold motion in a child with cerebral palsy. Clinically, the child presented with mild stridor, which worsened over months, eventually requiring emergency intubation. After an unsuccessful trial of medical management, microlaryngoscopy revealed abnormal adduction of the vocal folds during inspiration. This was successfully treated with periodic type A botulinum toxin injections to the vocal folds, sparing the child from tracheostomy.

Vocal cord dysfunction (also called paradoxical vocal cord motion) or paradoxical vocal fold motion (PVFM) is an event elicited by specific and nonspecific triggers in which its diagnosis is limited by the restricted number of available functional tests. This study was designed to appreciate the contribution of the spirometric changes elicited by the allergen-specific nasal provocation test (NPT) performed with Dermatophagoides pteronyssinus for the diagnosis of PVFM in subjects with known sensitization to this allergen...
