However, comprehensive guidelines for evaluating the defining characteristics of idiopathic unilateral vocal fold paralysis are still lacking. In the present study, we hypothesized that idiopathic unilateral vocal fold paralysis may have different clinical and neurologic characteristics from unilateral vocal fold paralysis caused by surgical trauma.<\/jats:p><\/jats:sec><jats:sec><jats:title>Study Design<\/jats:title><jats:p>Retrospective, case series study.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>Patients with unilateral vocal fold paralysis were evaluated using quantitative laryngeal electromyography, videolaryngostroboscopy, voice acoustic analysis, the Voice Outcome Survey, and the Short Form\u201036 Health Survey quality\u2010of\u2010life questionnaire.
