We present a retrospective study about our experience in the treatment of thyroid carcinoma. For that, between 1992 and 1997, we have collected 37 malignant thyroid tumours (15%) over 250 operations on thyroid gland by our ENT Service. We analysed several variables: Age, sex, personal antecedents, clinical symptoms, results of the complementary tests (thyroid hormones, ultrasonography, scintigraphy and FNAB), type of surgery complications and number of recurrences. The thyroid carcinomas, specially differentiated tumors, are an increasing pathology with tendency to affect females. In our serie usually they are solitary thyroid nodes, scintigraphically cold ones, in which FNAB as the best test. We think that a total thyroidectomy is the best treatment and it must be made by an ENT.
