[The diagnostic and clinical aspects of postoperative dysphonias following operations on the thyroid]

Postoperative dysphonia is not rare and in some cases life-treating complication in the thyroid surgery. Its emerge, autonomous, or attended with dysphagia and dyspnea is an early symptom for intraoperative lesion of n. laryngeus recurrens. The investigation is carried out over 21 patients with postoperative dysphonias, operated for euthyroid or hyperthyroid strumas and followed-up for a period of 3-10 months. Analysis of the results indicated that the main reason for postoperative dysphonias in thyroid surgery is the lesion of n. laryngeus recurrens. Along with this one is impressed by the fact that in 30% of the cases dysphonic complaints may owe to nonsurgical reasons.
