Evaluación de factores de riesgo foniátricos y generales de disfonía en tiroidectomías

Abstract

Thyroidectomy dysphonia Background: Dysphonia is one of the most important and frecuent complication in thyroidectomies. It incidence is between 0 and 20%. The frecuency of this complication depends on factors like the preope- ratory diagnosis, goitre volume, surgeon experience and other general factors that theoretically can affect it incidence. Aim: To evaluate a group of preoperatory risk factors usually not considerated that may have relevance in postoperatory dysphonia in thyroidectomies. Patients and Method: Survey and medical records of 56 patients operated between may and july 2009. Results: None of the risk factors included in this study increase de incidence of posthiroidectomy dysphonia. Conclusions: It seems that these theorical risk factors dont have a great infl uence in the incidence of dysphonia after a thyroidectomy. It can be eventually useful to submit these patients to a direct vocal cord evaluation before surgery, to obtain their real risk.
