A total of 55 dysphonic patients with vocal fold immobility diagnosed by laryngeal endoscopy were grouped according to probable clinical cause: 1) unknown; 2) traumatic; or 3) tumoral compression. They were submitted to LEMG by percutaneous insertion of concentric needle electrode. LEMG was conclusive in all patients and showed a majority with peripheral nerve injury. LEMG diagnosed peripheral nerve damage in 25 group 1, 12 group 2, and 11 group 3 patients. LEMG was normal in 4 patients, suggesting cricoarytenoid joint fixation. Central nervous system disorders was suggested in 2 and myopathic pattern in 1. As the major cause of vocal fold immobility is peripheral nerve damage, LEMG is an important test to confirm diagnosis.371-374engElectromyographyLaryngealadultagedarthropathycentral nervous system diseasecompressioncontrolled studydiagnostic testdysphoniaelectrodeelectromyographyendoscopyfemalehumanlarynx disorderlarynx injurylarynx tumormajor clinical studymalemyopathyneedleperipheral nerve injuryvocal cordAdolescentAdultAgedEndoscopyFemaleHumansLaryngeal NervesMaleMiddle AgedPrognosisRecurrent Laryngeal NerveVocal Cord ParalysisArtigoAcesso restrito2-s2.0-45442440721346461670550428
