Vocal cord paralysis: Clinical and electrophysiologic features

Abstract: Vocal cord paralysis may occur in isolation or as part of a constellation of findings in neurological disease. We investigated the pathophysiology of these disorders with laryngeal electromyography (LEMG). We studied 44 patients with idiopathic vocal cord paralysis, confirmed by laryngoscopy. The major LEMG finding, present in 29 vocal cords, was evidence of active or chronic denervation in the thyroarytenoid (TA), indicating recurrent laryngeal neuropathy. Denervation of the cricothyroid (CT) in 5 patients in… Show more

“…In this paper, we used flexible videonasolaryngoscopy as the gold standard. Moreover, we also included a CT scan and the clinical history in the diagnostic battery, since there are other reports which suggest that an image study can significantly contribute to the integral diagnostic process [5,7,18,19].…”

“…Desta forma o músculo CAL é inervado por um ramo único que deixa o NR 24 . Normalmente os músculos testados durante a EMG são o CT e o TA, e por meio deles indiretamente a atividade dos nervos laringeo superior e inferior, respectivamente 11,24,25 . Para Dedo 14 , todos os ramos para os músculos intrínsecos da laringe partem do NR após sua penetração na laringe, estando então protegidos pela c. c. Laringoscopia após retorno da mobilidade: phonation  ("i").…”
