Introduction: Since 1996, Dr. James Norman has successfully performed mimimally invasive radio-guided parathyroidectomy(MIRP) using intraoperative nuclear mapping with 99m Tc sestamibi scanning and radioactivity detection probe. Objectives: We aimed to introduce this new surgical technique and evaluate it's efficacy by our own experiences. Method: From May to October 1999, five consecutive patients with primary hyperparathyroidism underwent parathyroidectomy by using modified MIRP technique. 99m Tc sestamibi scanning was performed 1.0 or 1.5 hour before operation. After intraoperative localization of the tumor under the guidance of quantitative gamma counting with a NEVIGATOR probe, an unilateral small skin incision(3.0-4.0cm) was placed. Without a skin flap, the strap muscle was directly divided with the use of a Harmonic scalpel. After careful dissection, the parathyroid tumor was removed. Result: In all patients, a single adenoma could be easily detected and removed by this new technique. Mean incision length was 3.2cm(3.0-4.0cm) and operative time ranged from 40 to 110minute. All the patients were discharged within 2 days of surgery without any complication. Conclusion: This new operative technique could become the most minimally invasive alternative to the standard operative procedure for parathyroid adenoma.

Parotid canalicular adenoma is a benign neoplasm that is predominantly composed of branching and interconnecting cords of single or double rows of columnar epithelium in a very loose stroma. There has been considerable confusion in the literature concerning the terminology of canalicular adenoma. However, thesedays it has been newly-recognized as a discrete entity of the monomorphic adenoma group. Canalicular adenoma has a remarkable predilection for occurrence in the minor salivary glands such as the upper lip, in contrast with basal cell adenoma that occurs predominantly in major salivary glands such as the parotid gland. We have experienced a case of canalicular adenoma of the parotid gland in a 65-year-old woman. The patient had a palpable mass on the preauricular area for the last 15 years and recently noticed a mild pain and discomfort on the mass. Neck ultrasonography showed a low echogenic mass of 1.0cm in diameter in the right parotid gland and a neck CT scan showed a well-enhanced rectangular-shaped mass. A superficial parotidectomy was performed for the lesion and the final pathologic diagnosis turned out to be 'multifocal canalicular adenoma'.

The increasing risk of subsequent malignancy after treatment of malignant lymphoma is well known, which is mainly due to longer survival of these patients. Radiotherapy at an early stage of Hodgkin's disease or non-Hodgkin's lymphoma is accepted to be associated with future occurrence of secondary thyroid cancer. Nevertheless, the synchronous presentation of these malignancies is extremely rare. Well differentiated thyroid cancer, a slow-growing tumor that responds to therapy with surgery and radioactive iodine, is associated with prolonged survival. therefore, it is important to make this diagnosis in patients who show evidence of malignant lymphoma. Furthermore, appropriate treatment must be considered for thyroid cancer to improve the prognosis of these patients. We herein reported 4 cases of synchronous thyroid cancer and malignant lymphoma in patients who had not previously recieved radiotherapy or chemotherapy.

Solitary fibrous tumors are commonly arise in the pleura and less commonly in extrapleural sites. In head and neck area, solitary fibrous tumors can occur in nose, paranasal sinus, soft palate, epiglottis, thyroid, parotid and submandibular gland. To our knowledge, this is the 5th case of solitary fibrous tumor arising from the parotid gland in English literature. We report a case of solitary fibrous tumor occurred in the superficial lobe of right parotid gland which was successfully treated by superficial parotidectomy with preservation of the facial nerve.

Introduction: The surgical treatment of Graves' disease has several advantage such as rapid and long lasting therapeutic effect, relatively low incidence of postoperative hypothyroidism and recurrence. Because of less frequent but serious postoperative complications, the operation have not been casually used for treatment of Graves' disease. Hypoclacemia, hoarseness and hematomas are common complications after operative treatment. However, the causative mechanisms of these complications have not been well explained. Objective: We aimed to analyze the risk factors affecting the occurance of complications in surgical treatment for Graves' disease and to evaluate what are the causative mechanisms of postoperative complications. Patients and Methods: From January 1985 to December 1998, a total of 668 surgically treated patients for Graves' disease were enrolled in this study. The incidence of postoperative complications were analyzed in relation to types of surgery, preoperaive preparation, specimen weight, bleeding amount and remnant weight. Results: Postoperative complication was developed in 108(16.2%) of 668 patients. The most common complication was transient hypocalcemia in 85 cases(12.7%). Other complications were: Hematoma in 9 cases(1.3%), transient hoarseness in 5 cases(0.7%), permanent hypocalcemia in 6 cases(0.9%), permanent hoarseness in 3 case(0.4%). The important etiologic factors affecting the occurance of complications were preoperative preparation, perioperative thyroid weight, and remnant thyroid weight. Since 1993, the incidence of complication was more decreased than that in before. Conclusion: To decrease the incidence of postoperative complications of Graves' disease, the patients should be selected carefully, sufficient preoperative preparation should be achieved, and the operation should be performed by well-experienced surgeons.

유두상 갑상선암의 대부분은 서서히 진행하는 양호한 임상경과를 보이나, 일부는 저등급 혹은 미분화 갑상선암으로 전환되는 생물학적 특성을 보인다. 저자는 유두상 갑상선암 환자 358예를 적용된 치료방법과 치료결과를 분석하여 논란이 되고 있는 치료방법들 중에서 적절한 치료방법을 찾고자 본 연구를 시도하였다.% 568예중 동측엽절제술 및 협부 절제술 혹은 갑상선 아전 절제술 220예, 갑상선 전 절제술 혹은 근전절제술 143예, 종양적출술 5예였고, 이중 115예는 여러가지 형태의 경부 곽청술이 추가되었고, 150예는 수술후 방사성 동위원소 치료까지 추가되었다. 또 전 환자에서 TSH 억제를 위한 갑상선 호르몬 투여를 하였다. 추적 기간은 5년에서 12년까지 평균 8.5년이었다. Cady와 Rossia AMES Scoring system에 따라 저위험군과 고위험군으로 나누어 재발율과 사망율을 산출한 결과 저위험군 255예중 재발율 11.0%, 사망율 0.4%, 고위험군 65예중 재발율 36.9%, 사망율 20.0%을 보여 고위험군에서 현격히 불량한 예후를 나타내었다. 따라서 저자들은 유두상 갑상선암의 치료방법 선택은 일률적인 치료방법 보다는 환자 개인의 임상적 특성, 병기 등을 고려하여 저위험군에서는 소극적 수술을, 고위험군에서는 적극적인 수술과 수술후 보조치료를 시행하는 것이 바람직하다고 사료되었다.

Carotid body paraganglioma is uncommon, with appoximately 900 reports of it in the world literature, and with only 7 documented cases in the Korean literature. The classic carotid body para ganglioma develops in the bifurcation of common carotid artery and involves both the internal and external carotid arteries at it expands. The diagnosis may almost always be established preφeratively by selective angiography which shows a widening of the carotid bifurcation with a well defined vascular mass. Differential consideration of a single, lateral cervical mass in this location include branchial cleft cyst, neurogenic tumor, metastatic thyroid cancer, carotid body aneurysm and salivary gland tumor. Surgical therapy is the preferred method of treatment as these tumors are regarded as radioresistant. Because of their high vascularity and anatomical location, surgical removal of these tumors reguires a considerable degree of caution and a high degree of surgical expertise. With improved diagnostic and surgical technique, the morbidity and mortality has been reduced lately. This report details the management of 3 patients with carotid body paraganglioma who underwent safe resection by subadventitial dissection or using an internal vascular shunt.
