Thyroidectomy dysphoniaBackground: 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 preoperatory 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 don´t 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.Key words: Thyroidectomy, dysphonia. ResumenIntroducción: La disfonía es una de las complicaciones en tiroidectomías más importante y frecuente. Su incidencia varía entre 0 y 20%. Esta incidencia depende de factores como el tipo de diagnóstico preoperatorio, el volumen del bocio, la experiencia del cirujano y otros factores generales que pueden teóricamente infl uir. Objetivo: Evaluar un grupo no habitualmente considerado de factores de riesgo de disfonía en tiroidectomías. Pacientes y Métodos: Estudio prospectivo con análisis de fi chas clínicas y realización de una encuesta preoperatoria en 56 pacientes consecutivos. Resultados: En este estudio no fue demostrado estadísticamente un mayor riesgo de disfonía en pacientes con los factores de riesgos planteados. Conclusiones: Aunque los factores estudiados en esta muestra pueden teóricamente aumentar la incidencia de disfonía postiroidectomía, parecen no ser los más infl uyentes. Podría ser de utilidad realizar una evaluación dirigida otorrinolaringológica en estos pacientes para objetivar su real riesgo de disfonía postoperatoria.
