Background: Vocal cord paralysis is a common symptom of numerous diseases and it may be due to neurogenic or mechanical fixation of the cords. Paralysis of the vocal cords is just a symptom of underlying disease in some cases so, clinical diagnosis of the underlying cause leading to paralysis of the vocal cords is important. This study evaluates the causes of vocal cord paralysis. Materials and Methods: In a prospective study, 45 patients with paralyzed vocal cord diagnosis were examined by tests such as examination of the pharynx, larynx, esophagus, thyroid, cervical, lung, and mediastinum, brain and heart by diagnostic imaging to investigate the cause vocal cord paralysis. The study was ended by diagnosing the reason of vocal cord paralysis at each stage of the examination and the clinical studies. Results: The reason for referral was phonation changes 96% and aspiration 57% in the subjects. There was bilateral paralysis in 6.4%, left paralysis in 57.4% and right in 36.1% of subjects. The type of vocal cord placement was median in 44.8%, paramedian in 38.2%, intermedian in 10.6% and lateral in 6.4% of the subjects. The causes of vocal cords paralysis were idiopathic paralysis 8 (17%), tumors 9 (19.1%), surgery 28 (59%), lung tuberculosis 2 (4%). Conclusion: Vocal cord paralysis after thyroidectomy is common that is thyroid surgery so late, we need neiromonitor during thyroidectomy in our country. Possibility of malignancy should be excluded before marking idiopathic reason to vocal cord paralysis.
