Abstract
Purpose  LigaSure is a bipolar diathermy system, which achieves vessel sealing with reduced thermal spread. The device has been used
successfully in abdominal operations and because of its features, it has been applied recently in thyroid surgery to minimize
the risk of complications such as laryngeal nerve palsy and hypocalcemia, and also to reduce the operating time.

Methods  Between June and December 2005, we performed total thyroidectomy for various disorders in 105 patients. We used the LigaSure

Abstract
Purpose  (1) To determine the clinical profile of intrathoracic multinodular goiter (IMG); (2) to evaluate the results of surgery,
and (3) to analyze the incidence of malignancy and its evolution.

Methods  Two hundred and forty-seven operated cases of IMG were reviewed. These cases of IMG had all been diagnosed according to Eschapse’s
definition (>3cm below the sternal manubrium). The morbidity and postoperative evolution were analyzed. A comparative study

Abstract
Purpose  Substernal goiter is defined as a thyroid mass of which more than 50% is located below the thoracic inlet. In this article
we report the diagnosis, symptoms, thyroid function, treatment, and postoperative complications of 59 patients with substernal
goiter.

Methods  Between 1992 and 2005, 59 patients underwent surgery for substernal goiter at our institution. The indications for surgery
were multinodular goiter in 46 cases, follicular adenoma in two cases, and Hashimoto’s thyroiditis in one case. Ten patients

Abstract
Purpose  Total thyroidectomy (TT) with level VI and VII central neck dissection is the initial treatment for medullary thyroid carcinoma
(MTC) without identifiable neck metastasis. Level II to V lateral neck dissection is performed if neck metastasis is present
or suspected. We conducted this study to identify the frequency and clinical determinants of skip neck metastasis in MTC.

Methods  We reviewed the medical records of 32 patients who underwent TT and bilateral neck dissection for MTC. The clinical features
