Abstract
Paradoxical vocal cord motion (PVCM) is a condition where the vocal cords inappropriately and intermittently adduct during inspiration. In the pediatric population, PVCM is an affliction of adolescents. A variety of etiologies including laryngeal hyper-responsiveness, sensory defects, psychogenic origins, irritant exposure and more have been suggested however, the exact etiology of PVCM is not well understood. This arguably contributes to the prolonged time between symptom onset and definitive diagnosis. While the current mainstays in PVCM treatment include speech therapy, biofeedback and patient education, there remain key unanswered questions including: do patients continue to experience episodes of dysfunction after achieving early control with biofeedback, do patients still practice vocal cord relaxation techniques, and does PVCM affect participants' quality of life? This cross sectional study assesses the outcomes for patients diagnosed with PVCM at Children’s National Health Center over a 10-year period. Chart review identified fifty-two patients with PVCM, these patients were then given a REDcap-based survey assessing participants’ time from symptom onset to diagnosis, treatments recommended to them, their continued use of treatments, persistence of symptoms and impact on quality of life. Data collection and analysis is ongoing.
