RESUMO
<p><b>OBJECTIVE</b>To investigate the indications and complications of the total thyroidectomy in the management of thyroid cancer.</p><p><b>METHODS</b>Fifty-one patients with thyroid cancer operated with total thyroidectomy in a period from April 2007 to June 2010, were retrospective analyzed. There were 48 cases of papillary adenocarcinoma, 1 follicular adenocarcinoma, and 2 medullary carcinoma as well, 2 cases with hyperthyroidism, 3 cases with remote metastasis. There were 17 males and 34 females who in their age ranged from 5 years old to 82 years old with a middle age of 50 years old. Among the 45 cases who were initial surgical management patients, there were 17 T1, 13 T2, 7 T3, 8 T4; and there were 31 N0, 11 N1a, 3 N1b, 2 M1. The recurrent laryngeal nerve and the parathyroid gland, and supper laryngeal nerve were exposed routinely. Lymph nodes in Level VI were dissected in all patients, and Level II-IV dissected in 25 patients. ¹³¹I were administrated in 8 patients.</p><p><b>RESULTS</b>Patients were followed up from 1 month to 36 months. There were no patients died and lost of follow up. The two years survival rate was 100.0% (15/15). Pathological examination showed that the multiple focal disease rate was 42.2% (19/45), the cervical lymph nodes metastases rate was 51.0% (26/51). There was no permanent paralysis of recurrent laryngeal nerve and outer branch of supper laryngeal nerve. The permanent hypoparathyroidism rate was 3.9% (2/51). One case with contralateral lymph node metastasis was reoperated and survived without disease. Two cases with remote metastasis were alive with steadied disease.</p><p><b>CONCLUSIONS</b>Under the skilled hand, total thyroidectomy is a safe procedure in the management of thyroid cancer. Totally exposing the parathyroid gland and laryngeal nerve is the key point to prevent the major complications.</p>
