AI Article Synopsis
- The study aims to review the diagnosis and treatment of exercise-induced paradoxical vocal fold motion disorder (EPVFMD) based on patient experiences.
- A total of 104 patients were identified with EPVFMD, where a significant number showed symptoms only during exercise, with many initially having no signs of vocal fold motion issues but were diagnosed after exertion.
- Laryngeal control therapy proved effective, with 72% of those enrolled experiencing symptom improvement or complete resolution.
Article Abstract
Objectives/hypothesis: To review our experience with the diagnosis and treatment of exercise-induced paradoxical vocal fold motion disorder (EPVFMD).
Study Design: Single-institution retrospective review and cohort analysis.
Methods: A single-institution retrospective review was performed identifying patients with paradoxical vocal fold motion disorder (PVFMD). Patients with isolated exercise-induced dyspnea were selected for further review. Flexible fiberoptic laryngoscopy (FFL) performed on these patients were reviewed with regard to presence of laryngeal pathology as well as the presence of PVFMD at rest and/or with exertion. The type of therapy was reviewed. Symptom outcomes were graded as complete resolution, improvement, or unchanged following therapy.
Results: There were 758 patients who were identified with PVFMD. A total of 104 patients demonstrated symptoms of PVFMD that were only exercise related (EPVFMD). There were 93/104 (89%) patients who underwent a pre- and post-trigger FFL. Of these, 48/93 (52%) patients had no evidence of PVFMD on initial FFL. After subjecting these patients to exertion, 83/93 (89%) had evidence of PVFMD on postexertion FFL, and 39/93 (42%) patients had evidence of PVFMD on both pre-exertion and postexertion FFL. There were 87/104 (84%) patients who had evidence of laryngeal edema, and 23/104 (23%) had one or more laryngeal lesion on examination. A total of 67 patients were enrolled in laryngeal control therapy and attended at least one session, with 48/67 (72%) demonstrating improvement or complete resolution of their symptoms.
Conclusions: The diagnosis of EPVFMD is augmented with the addition of provocation testing. Findings of PVFMD can be identified at rest when asymptomatic. Laryngeal control therapy is an effective treatment for EPVFMD.

Introduction: There is a paucity of literature on pre-adolescent paradoxical vocal fold motion (PVFM), PVFM is a sub-type of inducible laryngeal obstruction. Studies typically focus on older patients, however the discovery of this entity in pre-adolescent pediatric patients has led to more questions about how this entity manifests differently and is treated differently in younger populations. Initially considered psychosomatic and commonly mistaken for asthma, PVFM etiology is now thought to be associated underlying neurologic conditions and may have irritant triggers with proposed mechanisms related to laryngeal hypersensitivity.

Introduction: Vocal cord dysfunction (VCD) is a complex disorder characterized by episodic adduction of the vocal folds during inspiration and expiration, which can lead to dyspnea, wheezing, cough, and acute-onset respiratory distress. Currently, there is a lack of standardized criteria among treating physicians across multiple disciplines, including otolaryngologists, pulmonologists, allergists, and speech and language pathologists, for diagnosis and treatment of VCD, although laryngeal-respiratory retraining therapy (LRT) has emerged as the preferred treatment modality.
Objective: In the present study, we examined the efficacy of LRT in patients presenting with a clinical diagnosis of VCD in the presence and absence of laryngeal adduction on laryngoscopy.

Article Synopsis
- Pediatric inducible laryngeal obstruction (ILO) is hard to diagnose and can take a long time for doctors to figure out what's wrong.
- A study looked at 78 kids with ILO from 2015 to 2023, finding that most of them were girls around 14 years old and many thought they had asthma.
- Management mostly included breathing exercises, which worked for some, but many kids still had symptoms after treatment, with it taking about a year on average for things to get better.

Introduction: Anaphylaxis is a severe and life-threatening systemic hypersensitivity reaction. The most frequently encountered causes are foods, drugs, and bee venom, but anaphylaxis may also occur idiopathically. Paradoxical vocal cord movement (PVCM), is a cause of upper airway obstruction due to abnormal adduction of vocal cords during inspiration and, to some degree on expiration.
