Background and Objectives：Supraglottic partial laryngectomy is oncologically sound surgical procedure for selected cases of laryngeal cancer which maintains physiologic speech and swallowing without permanent tracheostoma. The purpose of this study is to evaluate the oncologic and functional results of supraglottic partial laryngectomy and neck dissection for supraglottic cancer. Materials and Methods：Between 1991-2005, Twenty-three supraglottic cancer patients, underwent supraglottic partial laryngectomy, were studied retrospectively. There were 5 patients with cT1, 14 with cT2, 4 with cT3 and 11 patients with cN0, 1 with cN1, 10 with cN2, 1 with cN3. All patients underwent neck dissection and postoperative radiotherapy was added to twenty patients. They were reviewed with respect to primary subsites, extended subsites, treatment result, survival rate, factors affecting the prognosis, postoperative complication, time of decannulation and oral diet, and postoperative voice. Results：Among eleven patients with clinically negative node, six patients had pathologically positive nodes. So occult metastasis was 54.5%. Two patients recurred at cervical lymph node and one had distant metastasis to lung. Local and regional control were 100% and 91.3%. The overall 3-year and 5-year survival rate were 84%, 78%, respectively. Nineteen cases were squamous cell carcinomas and four were basaloid squamous cell carcinomas. Basaloid subtype was significantly affected to survival. Decannulation and oral feeding were possible in 100%. Conclusions：Supraglottic partial laryngectomy is oncologically safe and functionally good procedure in supraglottic cancers. Elective neck dissection is beneficial in management of occult cervical metastasis.

The neuorogenic tumor is known to be originated from neural crest, and the involved cells are Schwann cell, ganglion cell, and paraganglion cell. The Schwannoma, neurofibroma, and malignant schwannoma arise from the schwann cell, ganglioneuroma is from ganglion cell, and carotid body tumor and glomus tumor are originated from paraganglion cell. Authors reviewed thirty-eight patients of the neurogenic tumors in the head and neck, excluding intracranial tumor and Von-Recklinghausen disease, surgically treated at the Department of Surgery, Pusan Paik Hospital from January 1981 to May 1996. Of the 38 cases, 28 cases were schwannoma, 6 cases neurofibroma, 2 cases malignant schwannoma, and 2 cases paraganglioma. These tumors occurred at any age, but the majority of patients occurred in the fourth decade of life. There was female preponderance (M : F=1 : 1. 53) in sex ratio. The lateral cervical region was the most common distribution. 12 cases arose from the anterior triangle of neck, and 12 cases from the posterior triangle of neck. The major nerve origin of tumor could be identified in 30 cases (80%). 11 cases were treated by simple excision, and partial excision was 3 cases. Excision with parotidectomy 1 case, enucleation 11 cases, enucleation with parotidectomy 7 cases, radical neck dissection 1 cases, upper neck dissection 2 cases, suprahyoid dissection 1 case, Caldwell­Luc operation 1 case. The postoperative complications were hoarseness (2 cases), facial palsy (1 case), Homer syndrome (1 case), and hypoesthesia of tongue (1 case).

목 적: 국소 진행된 두경부암 환자에서 방사선치료를 포함한 근치적 치료 후 갑상샘기능저하증의 발생률을 분석하고자 후향적 연구를 실시하였다. 대상 및 방법: 2000년 1월부터 2005년 12월까지 본원에서 국소 진행된 두경부암으로 진단받고 근치적 목적으로 방사선치료 단독 또는 수술 후 방사선치료를 받은 환자 중 수술로 갑상샘을 절제하지 않았고, 방사선치료 전 갑상샘기능이 정상이며, 하부 경부림프절이 방사선치료 범위에 포함된 115명의 환자를 대상으로 본 연구를 시행하였다. 환자의 중앙연령은 59세(28~85세)이고 남자 73명, 여자 42명이었다. 원발병소의 위치는 구강, 구인두, 하인두, 후두, 그 외가 각각 18, 40, 28, 22, 7명이었으며, 편측 경부절제술을 받은 환자가 19명(16.5%), 양측 경부절제술을 받은 환자가 18명(15.7%), 방사선치료만을 시행한 환자가 78명(67.8%)이었다. 방사선치료는 6-MV X-ray를 사용하였으며, 통상 분할 조사법에 의해 하루 1.8~2 Gy 씩, 주 5회 조사하였다. 원발병소에 조사된 방사선량은 중앙값 70.2 Gy (59.4~79.4 Gy)이었으며, 하부 경부림프절에 조사된 방사선량은 중앙값 50.0 Gy (44.0~66.0 Gy)이었다. 추적관찰기간은 2~91개월이었으며, 중앙값은 29개월이었다. 결 과: 전체 115명 환자 중에서 38명(33.0%)의 환자에서 갑상샘기능저하증이 관찰되었다. 전체 환자의 1년, 3년의 갑상샘기능저하증 발생률은 각각 28.7% (33명), 33.0% (38명)이었으며, 갑상샘기능저하증 발생시기의 중앙값은 8.5개월(0~36개월)이다. 갑상샘기능저하증 발생에 영향을 주는 인자로 단변량분석결과 경부절제술 여부가 위험인자로 분석되었으나, 다변량분석에서는 통계적으로 유의한 관련 인자는 없었다. 결 론: 두경부 종양환자의 방사선치료를 포함한 근치적 치료 후 갑상샘기능저하증이 발생할 수 있으며, 대부분이 1년 이내 발생하므로 치료 후 갑상샘기능검사를 정기적으로 실시할 필요가 있다. 특히 경부 림프절제술 후 방사선 치료를 시행하는 경우 더욱 주의하여 갑상샘기능저하증의 발생을 확인해야 한다.

Postoperative stroke is uncommon even in elderly patients, who have a higher incidence of all types of postoperative complications. The mechanism of postoperative stroke is not certain, but can be explained by intravascular clottings originated from thrombus or embolus or by intracranial hemorrhage. In a 66-year-old male patient with current hypertension medication, who underwent both neck dissection for malignancy metastasis under general anesthesia, the left hemiparesis and delayed emergency were found postoperatively. After transferred to intensive care unit, he got the thrombolytic therapy and then the therapies to decrease the swelling of the brain on the diagnosis of cerebral infarction in the vascular distribution of the middle cerebral artery. A brain MRI definitely showed the midline deviation to the left of the right brain hemisphere due to the progressing edematous changes. As he got worse, the emergency neurosurgical operation was proposed but rejected by his family. He died at postoperative 3 days. In this hypertensive patient. perioperative stroke could be originated from the surgical stimuli on major vessels, which were inevitable in neck dissection during the operation. We report this case of the postoperative stroke, which could be highly possible to be associated with extensive head and neck surgery.

The patient a 24-year-old male, was shown to have milliary shadows on chest radiographs from the age of 20. He was temporarily treated for pulmonary tuberculosis without success. He had left thyroid mass and lymph node metastases in neck CT scan which was taken after admission but fine needle aspiration result in scanty cellularity. He underwent total thyroidectomy with left modified radical neck dissection and right selective neck dissection under the impression of differentiated thyroid cancer with bilateral neck metastases. Then he underwent 131I ablation treatment and postoperative whole body 131I scintigraphy revealed diffuse intensive uptake in the bilateral lung fields, demonstrating that the pulmonary lesions were metastases of the thyroid cancer.

목적 : 두경부암 환자에서 수술 및 수술 후 방사선치료가 갑상선 기능에 미치는 영향을 평가하기 위하여 전향적 연구를 시행하였다. 대상 및 방법 : 1986년 9월부터 1994년 12월까지 수술후 방사선치료를 받은 두경부암 환자 중 추적 관찰이 가능했던 71예를 대상으로 하였다. 환자의 연령분포는 32세부터 73세였고, 중간값은 58세였으며, 여자 12예, 남자 59예였다. 원발 병소부위는 후두가 34예로 가장 많았고, 구강 12예, 구인두 1예, 하인두 13예, 상악동 2예, 타액선 3예, 근원 불명 전이성 경부암 6예였다. 전후두절 제술 및 경부곽청수술을 시행한 환자는 45예였고, 경부곽청수술만 시행한 환자는 26예였다. 모든 환자에 대하여 방사선치료 전 및 방사선치료 후에 정기적으로 임상검사 및 갑상선 기능검사 (T3, T4, free T4, TSH, antithyroglovulin antibody, antimicrosomal antibody)를 시행하였다. 방사선량은 40.6Gy에서 60Gy였고 중간값은 50Gy였으며 추적관찰 기간은 3개월에서 80개월이었다. 결과 : 갑상선 기능 이상의 빈도는 $56.3\%(40/71)$였다. 31예 $(43.7\%)$는 갑상선 기능이 정상이었고 7예 $(9.9\%)$는 임상적 갑상선 기능저하증이었으며 33예 $(46.5\%)$는 준임상적 갑상선 기능저하증이었다. 갑상선 기능항진증, 갑상선 결절, 악성종양은 발견되지 않았다. 경부곽청수술군보다 전후두절제술 및 경부곽청수술군에서 갑상선 기능 이상이 일찍 발생하였다(p<0.05). 방사선치료 후 갑상선 기능 이상의 발생 빈도에 영향을 준 위험인자는 전후두절제술 및 경부곽청수술과 방사선치료의 병용요법 (P=0.0000)이었다. 전후두절제술 및 경부곽청수술군 45예 중 36예 $(80\%)$에서 갑상선 기능 이상이 발생하였으며 경부곽청수술군 26예 중 4예 $(15.4\%)$에서만이 갑상선 기능이상이 발생하였다. 결론 : 두경부암 환자에서 수술 및 방사선치료 후 갑상선 기능 이상은 비교적 흔한 합병증이며, 갑상선 기능 이상의 발생 빈도에 영향을 미치는 인자는 전후두절제술 및 경부곽청수술과 방사선치료의 병용요법이었다. 갑상선 기능 이상을 조기에 발견하여 치료하기 위하여 방사선치료 전 및 방사선치료 후에 정기적인 갑상선 기능검사가 필요할 것으로 사료된다.

The primary treatment of oral cavity cancer is still surgery. By discussing the surgical treatment of oral cavity cancer, the basic concept of head and neck surgery could be thoroughly reviewed. The oral cavity is defined as the hard palate and the anterior 2/3 of the tongue. With appropriate reconstruction, most defects can be repaired without a significant change in quality of life, unlike in the oropharynx or hypopharynx, where aspiration problems frequently occur. The selection of a surgical approach that can provide an appropriate field of view to obtain a resection margin of 5 mm or more has become the core of head and neck surgery. The role of prophylactic neck dissection is also well established in oral cavity cancer patients. Mandibulotomy for access to the oral cavity or mandibulectomy due to cancer invasion requires bony surgical techniques, and reconstruction also requires bone tissue reconstruction techniques as well as soft tissue. Therefore, oral cancer surgery is the most important primary area where all techniques of head and neck surgery are mobilized.
