PURPOSE: Vocal cord dysfunction (VCD) is characterized by the paradoxical adduction of the true vocal cords during inspiration and is manifested by dyspnea, wheezing and chest tightness. VCD is often misdiagnosed as asthma, which leads to overtreatment and unnecessary utilization of healthcare resources. Direct laryngoscopic visualization is the gold standard for diagnosis of VCD but is time consuming and not readily available. There are several clinical and spirometric findings that may predict VCD. A clinical scoring system, the Pittsburgh Vocal Cord Dysfunction Index, has been published as a validated tool to distinguish VCD from Asthma. It identified symptoms of throat tightness, dysphonia, the absence of wheezing, and the presence of odors as a symptom trigger; as key features of VCD compared with asthma. We performed a retrospective review of patients presenting to our clinic for a laryngoscopy to find which variables, if any, could be used as part of a predictive tool for VCD. However, only two variables were identified as correlating with VCD, resulting in an unsuccessful attempt to develop a scoring system. We herein report the results.
