• Abstract:

  The paralysis of pleats vocal cords (PPV) is a pathology resulting from the lesion of the superior and recurrent laryngeal nerves, which innervate the intrinsic muscles of the larynx. Common symptoms include voice change, hoarseness, and aspiration. of food. The objective of this work is to carry out a study on the most frequent of that paralysis, well as about sex and age of patients affected. This is a systematic review, with articles from 2014 to 2018 about of the PPV, selecting the 10 most relevant. The observed results were the equitable incidence between the sexes, with a mean of 54.3 years, and the highest prevalence due to iatrogenic injury in thyroidectomy surgeries. PPV is generated per lesion us nerves laryngeal higher and/or recurrent, per surgeries, tumors, intubation. patients affected present hoarseness, dysphonia and dyspnea. Electroneuromyography of the larynx muscles is a good method for elucidate such cases. Therefore, it is important to consider factors such as age and prevalence in causes for that condition, the end in catch up a diagnosis need. Still, no if can leave out less common causes, such as laryngitis, then only considering all those factors, it is possible to define a more efficient therapeutic approach.
