Background and Objective:A post-operative hypertrophic scar of the anterior neck is the leading complaint of the patients who underwent conventional thyroid surgery. In order to minimize the post-operative scar of the anterior neck, we performed thyroidectomy via axillary approach using operating microscope and a specialized retractor to determine technical feasibility. Patients and Methods:From January 2005 to December 2006, we performed thyroidectomy via axillary approach under operating microscope(f=400mm, ${\times}2.5$;OPMI $pico^{(R)}$;Zeiss, Germany) for benign unilateral nodule in 25 cases(all female, average age 34.5yrs). Under general anesthesia less than 7cm of skin incision was made in the axilla of ipsilateral side. A subcutaneous tunnel went over the pectoralis major muscle and the clavicle, and then through the sternocleidomastoid muscle and sternothyroid muscle was excised. The area around the thyroid was sufficiently dissected, and then a retractor designed for exposure via axillary approach was placed within the tunnel and under operating microscope thyroidectomy was performed. Results:There were 17 cases of thyroid nodulectomy and 8 cases of subtotal lobectomy. The mean average operative time was 102.64minutes. Postoperative complications included one case of postoperative bleeding, one case of temporary vocal cord paralysis, two cases of delayed wound healing, two cases of paresthesia of shoulder and arm, and two cases of hypertrophic scar of the axilla. Postoperative histopathology includes 17 cases of adenomatous hyperplasia, six cases of cyst, and two cases of follicular adenoma. For all cases hospitalization period was two days. Conclusion:Thyroidectomy via axillary approach under operating microscope has a good cosmetic advantage without a post-operative scar of the anterior neck. The procedure is simple due to direct vision using operating microscope, easy to identify important structures by magnifying them, and therefore surgical time can be reduced.
H$\"{u}$rthle cell neoplasm of the thyroid gland is an uncommon, but potentially malignant lesion. However, in many instances, the malignant potential of the H$\"{u}$rthle cell neoplasm is very difficult to judge histologically. For this reason, the biologic behavior of this tumor and its optimal treatment have come under considerable debate in recent years. In order to review the clinicopathologic features of the H$\"{u}$rthle cell neoplasm and to determine its optimal treatment modalities, we studied 26 patients with path logical proof of H$\"{u}$rthle cell tumor from January 1987 to September 1997. We also performed an immunohistochemical study using the monoclonal antibodies against antigen CD34 for the angiogenic activity of this tumor and evaluated the differences of microvessel density(MVD) between benign and malignant tumors. The age of the patients ranged from 1 to 71 years with a mean of 44.2 years. There were 6 males and 20 females(M : F= 1 : 3.3). The accuracies of fine needle aspiration biopsy and frozen section were very low; 6.3% and 34.8%, respectively. There were 20 benign tumors and 6 malignant tumors(23.1%). All the malignant tumors were microinvasive(intermediate) type which had minimal capsular invasion and most of them(5 cases) were diagnosed postoperatively. Any specific clinicopathologic differences were not seen between benign and intermediate groups. Most of the cases had conservative surgeries(15 ipsilateral lobectomy-isthmusectomy, 7 subtotal thyroidectomy) while total thyroidectomy was performed in 4 cases. Of the cases with malignant tumor, 2 had ipsilateral lobectomy-isthmusectomy, 3 had subtotal thyroidectomy and the remaining 1 had total thyroidectomy. Mean size of the tumors was 3.0 cm(0.1- 8.5 cm) in the greatest diameter and multiple tumors were seen in 6 cases(23.1 %). During the follow-up period, only one recurrence(3.8%) of benign tumor occurred but distant metastasis or cause-specific death was seen in the benign or intermediate groups. Mean MVDs of the benign(n=13) and intermediate(n=6) groups were $121.7{\pm}35.3$ and $114.3{\pm}31.7$, respectively and there was no statistical significance between them. In conclusion, because of the low accuracies of fine needle aspiration biopsy and frozen section for the H$\"{u}$rthle cell neoplasm, the extent of surgery could be individualized based on permanent pathologic examination; Conservative surgery would be adequate for patients with benign or intermediate H$\"{u}$rthle cell neoplasm and total or near-total thyroidectomy for those with definite malignancy.
Papillary carcinoma of thyroid is the most common thyroid carcinoma carrying better prognosis than the other thyroid carcinoma. Among the variants in the papillary thyroid carcinoma, the tall cell variant and diffuse sclerosing variants have more aggressive behavior than the classic papillary carcinoma. Recently, a new variant of papillary carcinoma has been reported which was named warthin-like tumor of the thyroid because of its close histologic resemblance to a tumor encountered in the salivary gland, carrying favorable prognosis. Since then, in English literature, a few cases have been reported, but in Korea have not been reported yet. We report a case of warthin-like tumor of the thyroid. A 38 year-old woman who had neck mass, was administered for thyroid surgery due to suspicious thyroid cytology. Right total thyroidectomy and left subtotal thyroidectomy with central compartment node dissection was performed. Histologic diagnosis was made as a Warthin-like tumor of the thyroid.
Ten patients with $H\"{u}rthle$ cell tumor of the thyroid gland from Dec. 1987 to Sep. 1992 were reviewed to delinate an acceptable policy of treatment. Patients varied from age 23 years to 66 and consisted of nine females and one male, most of whom had an asymptomatic solitary cold nodule. Four patients had benign neoplasm and six patients had malignant neoplasm proven by capsular or vascular invasion or nodal metastasis. Associated thyroid lesions occurred in five patients, three adenomatous goiter, one Graves' disease and one follicular cell carcinoma. Surgery consisting of lobectomy and isthmectomy in four patients, bilateral subtotal thyroidectomy in one patients, total thyroidectomy in five patients. Lymph node dissection was not performed. Only one patient was experienced transient hypocalcemia. The period of observation varied from 15 to 58 months(mean, 30.5 months). Although our case was small and short follow up period, there were no recurrences or deaths. We suggested early aggressive surgical approach was appropriate because of lower recurrence rate and fewer operation, high bilateralism, lower surgical complication.

Objectives: We'd like to give help in diagnosis and treatment of children's thyoid tumor through our clinical experiences and reference consideration. Materials and Methods: The authors report their experiences with 33 cases of thyroid tumor in patients younger than 16 years of age who were treated at Presbyterian Medical Center from 1979 to 1995. Results: 1) Girls were more predominant than boys by a ratio of 5.6:1. The peak incidence was in the 15 years old of age. 2) The final diagnosis in the 33 patients were thyroid carcinoma in 12 cases, nodular goiter in 6 cases, adenoma in 6 cases, Graves disease in 4 cases, Hasimoto's disease in 4 cases and cyst in 1 case. 3) All of 12 patients with thyroid cancer had nodular tumor. 4) In 5 of 6 patients with palpable cervical lymphadenopathy, the final diagnosis was thyroid carcinoma. 5) Delayed diagnosis arose in 6 of 12 thyroid carcinomas which were treated for long periods as benign disease. 6) The surgical procedures were total thyroidectomy in 3 cases, subtotal thyroidectomy in 13 cases and thyroid lobectomy in 17 cases. 7) 11 of 12 patients with thyroid carcinoma had subtotal or total thyroidectomy with lymphnode dissection and only one had lobectomy. 8) The overall rate of postoperative complication was 3%(1 of 33 patient). 9) Postoperative $^{131}I$ therapy was done in 7 case because of recurrence and distant metastasis in six and severe local invasion in one. 10) In thyroid cancer, the metastatic rate of lymph node at initial surgery was 81%(9/11) and rate of recurrence was 50%(6/12). 11) Patients with thyroid carcinoma were followed up for a mean of 12 years but only one died as a result of thyroid carcinoma 3.5 years later. Conclusion: The authors suggest that thyroid tumors in childhood should receive the benifit of joint management by endocrine pediatrician and experianced surgeons with an agreed protocol of diagnosis and management. We, also, recommend aggressive surgical and $^{131}I$ treatment as the most effective regimen for children with thyroid carcinoma.
A 30 year-old female patient with papillary thyroid carcinoma received her fifth radioiodine ablation therapy after the subtotal thyroidectomy. The scan, which was peformed one week after the last therapy, revealed residual uptake in the thyroid bed and uptake in the anterior mediastinum suggesting metastasis. However, further evaluation of the thorax with chest CT and camera-based FDG PET confirmed normal thymus without metastatic focus. Occasionally thymus remains intact in adult and has avidity for I-131 and FDG. Therefore, normal thymus (instead of metastasis) should be considered in patients with well differentiated thyroid carcinoma and anterior mediastinal radioiodine uptake.
We managed surgically a case of local recurrence in esophageal cancer Twenty month after transthoracic subtotal esophagectomy and csophago-gastrostomy, he su(fared from dysphagia. Chest CT and percutaneous needle aspiration biopsy showed . Local recurrence involving residual esophagus, thyroid gland, posterior membraneous portion of trachea. We did cervical esophagectomy, laryngectomy thyroidectomy, partial resection of trachea and reconstruction with free jejunal antograft successfully.
Purpose: Surgery for thyroid gland requires skin incisions that can result in postsurgical neck scar. To overcome this, many surgeons performed a endoscopic thyroidectomy. But, this approach had a some problems. One of postoperative problems, iatrogenic cervical dystonia (CD) may occur. At common, CD is defined as a syndrome characterized by prolonged muscle contraction causing twisting, repetitive movements or abnormal posture. Botulinum toxin A (BTA, Botox$^{(R)}$, Allergan, Irvine, CA, USA) is well known treatment agent in the treatment of CD. So, the authors applied BTA injection in rare case with iatrogenic CD resulting in endoscopic thyroidectomy. Methods: A 43-year-old female had endoscopic subtotal thyroidectomy operation 3 years ago. She had symptoms such as progressive cervical pain, abnormal neck posture, depression, and sleep difficulty. About 1 year later, the patient who had previous myomectomy of the clavicular head of sternocleidomastoid muscle, however, symptoms were not improved. And then the patient received BTA therapy in our department. The 2 units per 0.1 mL solution was administered in a 1 mL tuberculin syringe. Results: The dose of BTA used in the patient was 36 units for vertical platysmal bands, superficially, and 10 units for ipsilateral sternocleidomastoid muscle, intramuscularly. After 2 weeks, additional the dose of BTA used in the patient was 5 points for remained scar bands, superficially. Complications related to injection such as significant swallowing difficulties, neck muscle weakness, or sensory change were not observed. In 9 months follow-up, the patient maintained a good result from the method of BTA injection alone. Conclusion: The basic concept is selective denervation for the hyperactive individual muscles and scar bands. We conclude that BTA is an effective and safe treatment for CD despite the iatrogenic and complex presentation of this complication.
Traditionally, wound drainage after thyroid or parathyroid surgery has been widely used to prevent airway obstruction due to accumulation of hematoma or seroma within the paratracheal dead space. Recently, however, the routine use of drains after thyroid or parathyroid surgery has become a matter of controversy. To determine whether the rouine use of drains after thyroid or parathyroid surgery is warranted, a prospective study on the complications after various types of thyroid or parathyroid surgery without wound drains was conducted. Three hunded sixty-six consecutive patients underwent thyroid or parathyorid surgeries by one surgeon from January through December 1994 were included in this study. Of these, only 38 patients (10.4%) required the wound drains. Indications for drainage included the patients with a large dead space(n=9) or wet operative field at the conclusion of surgery(n=11), and patients with radical neck disection(n=18). In the remaining 328 patients(89.6%), the wounds were closed without drains after thyroid lobectomy and isthmusectomy(n=226), bilateral subtotal thyroidectomy(n=21), total or near-total thyroidectomy(n=62), isthmusectomy(n=9) and parathyroid surgery(n=l0). Histologic findings revealed benign tumors in 214(65.2%), carcinoma in 89(27.1%), Graves' disease in 15(4.7%), hyperparathyroidism in 7(2.1%) and parathyroid cyst in 3(0.9%). Among the 328 patients without drain used, wound related complications were seen in only 15 patients(4.6%); 12 patients with seroma and 3 patients with hematoma. All but one complications could be controlled by two or three aspirations, and the remaining one patient required re-exploration. There were no instances of laryngeal nerve palsy or wound infection. The mean length of hospital stay after surgery was 2.8 days with a range of 1 to 11 days. These results support the routine use of drains is not warranted in most thyroid or parathyroid surgeries.
The authors present 15 cases in which the diagnosis of thyroid cancer was established pathologically among 300 cases of Graves' disease diagnosed clinically at Chosun University Hospital, from January 1982 to December 1994. These cases were analyzed in order to establish guidelines for prophylactic node dissection as part of the initial management of thyroid cancer in patients with Graves' disease. The analysis revealed the following: 1) The average age of the 15 patients was 34.5 years and the male: female ratio was 1 : 4.0. 2) In 8 of the 15 cases(53.5 %) the occult thyroid carcinoma measured less than 1.5cm. 3) The degree of invasivensess manifested in these fifteen cases may be summarized as follows: In Group 1(6 cases) there was absence of microscopic capsular invasion and of lymphnode metastasis. In Group 11(4 cases) threre was microscopic capsular invasion but absence of lymphnode metastasis: In Group III(4 cases) there was either extrathyrodal soft tissue invasion or regional lymph node metastasis: and in Group IV(1 case) there was lymphnode invasion and distant metastasis. 4) Thirteen patients underwent either subtotal or near total thyroidectomy, and 2 patients underwent total thyroidectomy. Seven patients underwent some type of neck dissection, as follows: anterior compartment dissection in one of the cases in Group I; functional neck dissection in two cases and jugular node dissection in one case in Group II; and anterior compartment dissection in one case and modified radical neck dissection in two cases in Group III. 5) The author propose the following guidelines for prophylactic initial node dissection when a unexpected coexisting thyroid carcinoma in encountered on the frozen section during the surgical management of Graves' disease; Group I cases do not require initial neck dissection in group II, anterior compartment dissection in sufficient. In Group III, either jugular node dissection or functional neck dissection should be performed, and followed by postoperative Ra$^{131}$I therapy, Group IV requires Ra$^{131}$I therapy with or without modified radical neck dissection depending in the patient's condition.
