The papillary carcinoma is the most common malignant neoplasm of thyroid gland and the prognosis is better than anyother type of thyroid carcinoma. However, the thyroid is closed to the important organs such as esophagus, trachea and larynx, there are some possibilities to invade these organs. In case of advanced disease, not only surrounding structures but also mediastinum and cervical lymphatic chain can be involved or distant metastasis develops frequently. Therefore in these cases the prognosis is worse and the rate of inoperable case is more than those of non-metastatic group. Generally, the treatment modality for papillary thyroid carcinoma consists of surgery, postoperative thyroid hormone and radioiodine therapy. If the tumor invades surrounding structures, cervical lymph node or mediastinum, total thyroidectomy and wide excision of tumor invaded area including mediastinal dissection and neck dissection is necessary. Recently, the authors have experienced a case of locally invasive and recurred papillary thyroid carcinoma without treatment for 7 years. The patient was performed previously thyroid lobectomy and isthmusectomy 13 years ago. We had determinded surgical therapy for this patient and performed mass excision with overlying skin, completion total thyroidectomy, right type I modified radical neck dissection, left lateral neck dissection, thoracotomy with supramediastinal dissection, shaving of diffusely involved trachea and skin defect reconstruction with pectoralis major myocutaneous flap. After operation 2 cycles of radioiodine therapy were taken. Now the patient is following up at the outpatient base and no evidence of disease state for postoperative 16 months. So we report on this case with a brief review of literature.

Purpose: The purpose of this study is to evaluate the transverse cervical artery of those who received preoperative radiotherapy or radical neck dissection and those who are unable to utilize the branch of external carotid artery system, which are most commonly used as recipient artery in head and neck reconstruction. Methods: 10 patients were selected as head and neck cancer candidates for study. 8 patients received radical neck dissection or modified radical neck dissection and 3 patients underwent preoperative radiotheraphy. In call cases, reconstruction using free flap was performed with transverse cervical artery as recipient artery and posterolateral cervical vein or transverse cervical vein as recipient vein. Results: Partial necrosis of flap due to wound infection was noted in one case and successful microsurgery was achieved in all other cases. The average pedicle length was 9.3 cm and all arteries underwent end to-end anastomosis. In 7 patients, posterolateral cervical vein was used as recipient artery and transverse cervical vein was utilized in 3 patients. Conclusion: In cases where recipient artery from external carotid system cannot be utilized due to preoperative radiotherapy or radical neck dissection, the transverse cervical artery can be an alternative option of choice. Due to diverse variations of transverse cervical vein as a recipient vein, the posterolateral cervical vein may be considered in such cases.

Background and Objectives: Medullary thyroid carcinoma(MTC) is a rare tumor derived from the parafollicular C cells of the thyroid gland accounting for 5-10% of all thyroid malignancies. In Korea, there has been a few case report of medullary thyroid carcinoma(MTC) but their clinical analysis were not exactly studied. So, we made clinical study of 10 patients diagnosed as medullary thyroid carcinoma. Materials and Methods: We reviewed clinical data of 10 patients who were diagnosed as medullary thyroid carcinoma(MTC) from April 1973 to August 1998 at National Medical Center. Results: The incidence of MTC was 2.3% of all thyroid cancer and their mean age were 44.2 years old. Preoperative thyroid scan showed cold nodule in all patients and thyroid function test(TFT) was within normal range. Of the 10 patents, only 4 patients had diagnosis of MTC in preoperative fine needle aspiration biopsy. All the patients underwent total thyroidectomy with central neck dissection. Two patients with cervical lymph node metastasis underwent total thyroidectomy, central neck dissection and modified neck dissection. Two patients (20%) showed recurrence at the site of neck, lung, mediastinum, bone and liver. Conclusion: Most MTC is sporadic form and have peak incidence in the fifth decade and female preponderance. Preoperative fine needle aspiration biopsy is considered to be a clinically useful diagnostic method, but its accuracy is not considered as much high as others. Total thyroidectomy with central neck dissection may be an useful surgical modality in treating medullary thyroid carcinoma.

The authors reviewed 106 cases of parotid gland tumor at Presbyterian Medical Center seen during the past 10 years between January, 1986 and December, 1995. The results were obtained as follows; 1) 86 cases(81.1%) were benign tumors and 20 cases(18.9%) were malignant tumors. 2) Overall male and female sex ratio was 1 : 1.4. 3) For benign tumors, the mean age was 47.9 and for malignant tumors, the mean age was 43.4. 4) Clinical manifestations in benign tumors were palpable mass in 86 cases(100%), pain in 6 cases(6.9%), facial nerve palsy in 2 cases(2.3%), lymphadenopathy in 1 case(1.2%); and in malignant tumors, palpable mass in 20 cases(100%), pain in 7 cases(35%), facial nerve palsy in 2 cases(10%) and lymphadenopathy in 3 cases(15%). Thus, the presence of pain, facial nerve palsy and lymphadenopathy suggest malignant tumors. 5) Operative procedures in benign tumors included superficial parotidectomy in 53 cases(61.6%), total parotidectomy in 10 cases(11.6%), local excision in 23 cases(26.7%); and in malignant tumors, superficial parotidectomy in 3 cases, total parotidectomy in 1 case, local excision in 1 case, superficial parotidectomy with supraomohyoid neck dissection in 6 cases, total parotidectomy with supraomohyoid neck dissection in 8 cases, total parotidectomy with radical neck dissection in 1 case. 6) Postoperative complications in benign tumors were transient facial nerve palsy in 14 cases, Frey's syndrome in 2 cases. In malignant tumors complications included transient facial nerve palsy in 3 cases and permanent facial nerve palsy in 1 case. 7) Pleomorphic adenoma was the most common benign parotid tumor and mucoepidermoid carcinoma was the most common malignant tumor. 8) In our review of 20 patients with malignant parotid tumors, all patients who received supraomohyoid neck dissection and postoperative radiation therapy remain alive from 1986 to 1995 years. Two deaths in this series were adenoid cystic carcinoma patients who failed to receive postoperative radiation therapy. These series of cases have been studied in order to determine whether supraomohyoid neck dissection and postoperative radiation therapy may have further therapeutic effect.

Chylous fistula is a rare complication occurring after radical neck dissection. Previous reports on neck dissection described an incidence of about 1% to 2%. We report a case of chylous fistula that occurred after radical neck dissection for squamous cell carcinoma of left lower gingiva and mandible in a 52-year-old man. We successfully managed the fistula by the following conservative measures : bed rest with head elevation, continuation of closed suction drainage, and dietary management to decrease the rate of chyle formation.

연구배경 : 식도암은 근치율이 낮고, 광범위 림프절 절제후에도 그 성적이 나쁜 편이다. 따라서 경부 림프절 절제가 식도수술결과에 미치는 효과를 알아보고자 식도수술 환자에서 경부림프절 전이가 된 환자를 조사하였다 대상 및 방법 : 1994년부터 1996년 6월까지 본원에서 흉부식도암 수술을 받은 32명의 환자 중 고식적 수술을 시행받은 25명의 환자를 대상으로 하여 경부림프절 절제의 유무를 기준으로 두 그룹으로 나뉘어 연구하였다. 두 그룹 모두 흉부식도 전절제술과 동반하여 종격림프절과 복부림프절 절제를 시행하였으나 B그룹은 양측 경부림프절 절제를 추가하여 시행하였다. 결과 : 수술합병증은 두 그룹 사이에서 의미있게 차이가 나지않았다. t수술사망과 병원사망은 두 그룹 모두에서 보이지 않았다. 그러나 평균 마취시간은 B그룹에서 의밌게 더 길었다.(평균 마취시간 90분). B그룹에서 27%가 경부림프절 전이를 보였다 결론 : 그러므로 경부림프절 절제는 흉부식도암 수술에서 의미있는 수술방법이라고 할 수 있다. 장기생존율의 비교가 더 필요하리라고 생각한다.
