Paradoxical Vocal Fold Motion is a laryngeal disorder where sudden, inappropriate adduction of the true vocal folds during inspiration causes dyspnea. Due to the respiratory distress found with this disorder, it is often misdiagnosed for asthma and a correct diagnosis is often not made until after the patient has undergone costly office visits, procedures, and pharmaceutical interventions (Ibrahim et. al, 2007). It may take years of inappropriate treatment with no benefit to receive a correct diagnosis for this disorder. Though the exact cause of PVFM is idiopathic, four main pathogenetic mechanisms have been suggested in the literature: laryngeal hypersensitivity, altered autonomic balance, direct stimulation of the sensory nerve endings in the upper or lower respiratory tract, and hyperventilation (Patel et. al, 2015). The aim of this poster presentation is to provide education on how to identify traits of PVFM differentially from asthma, to learn the triggers and causes of this disorder, and how to manage the symptoms of PVFM.
