Background and Objectives: Neck metastasis is one of the most important prognostic factor in head and neck squamous cell carcinoma. Recently, elective neck dissection has been widely accepted for accurate pathologic staging and elective treatment of neck. Occult metastasis rate of laryngeal cancer varies widely depending upon authors. To evaluate the rate and characteristics of occult metastasis and efficacy of the elective neck dissection in clinical N0 laryngeal cancer, we performed this study. Materials and Method: Seventy two patients (supraglottic cancer: 19 cases, glottic cancer: 53 cases) who underwent surgery for laryngeal cancer as an initial treatment from 1993 to 2002 were evaluated. All was underwent elective neck dissection at the time of surgery for the primary treatment. The record of patients and pathologic report were reviewed retrospectively. Results: Occult metastasis rate of supraglottic and glottic cancer were 42.1% (8/19) and 9.4% (5/53), respectively. According to T stage, the occult meastasis of supraglottic and glottic cancer was 20%, 0% in T1, 36.4%, 0% in T2, 100%, 40% in T2, 100%, 20% in T4, respectively. Occult metastasis was mostly confined within level II (69.2%), III (76.9%), IV (23.1%). Conclusion: Based on ours results, elective neck dissection might be needed in treating of clinically N0 all supraglottic cancer and advanced T3, T4 glottic cancer.

Multiple symmetric lipomatosis is a rare disease characterized by progressive growth of subcutaneous fat masses which are located symmetrically at neck, shoulders, chest, abdomen and groin. Recent surveys revealed a high incidence of combined somatic and autonomic neuropathy. The exact cause of the disease is not known. We have experienced one case of multiple symmetric lipomatosis with mediastinal involvement with symptomatic compression of trachea. The patient was a 55-year-male, complaining of dyspnea and slowly enlarging multiple symmetric masses at the neck, shoulders, chest, abdomen, flank and groin over a period of 10 years. He had a habit of excessive alcohol intake for many years. The fatty masses in the neck and the upper mediastinum including peritracheal region were excised through transverse cervical incision. But, because of the incomplete excision of peritracheal fatty tissue, we performed reoperation for the relief of residual tracheal compression at the 15th postoperative day. Two days later emergent tracheostomy was performed due to postoperative pneumomediastinum and subcutaneous emphysema. He could discharge with permanant tracheostomy.

Purpose: Cervical lymph node metastasis is the most important factor of the prognosis and therapeutic planning in head and neck cancer. With increasing interest of minimally invasive neck surgery, more accurate preoperative assessment of cervical lymph node becomes more essential. We evaluated the diagnostic accuracy of $^{18}F$ FDG-PET in the assessment of lymph node metastasis in patients with primary head and neck cancer and compared the results with those of CT/MRI. Materials and Methods: Thirty-two patients (M/F=27/5, $56{\pm}10yr$) with biopsy proven head and neck cancer (16 supraglottic cancer, 9 tongue cancer, 7 others) underwent FDG-PET and CT/MRI (25/7) within 1 month before neck dissection. Based on lymph node level, the diagnostic sensitivity and specificity of FDG PET and CT/MRI for the metastasis of cervical lymph node were compared. Results: Of 153 lymph node levels dissected in 32 patients, 32 lymph node levels of 19 patients were positive for metastasis by histopatholologic examination. The overall sensitivity and specificity of FDG-PET were 88% (28/32) and 93% (113/121), whereas those of CT/MRI were 56% (18/32) (p=0.002) and 92% (112/121), respectively. The diagnostic sensitivity and specificity of FDG-PET were different according to location of lymph node levels, and those of ipsilateral level 11 were lower than those of other levels. Conclusion: FDG-PET is more sensitive in detecting metastatic cervical lymph node in head and neck cancer than CT/MRI. FDG-PET might be useful in guiding the extent of neck dissection.

This study was conducted not only to find out the effect of straight body exercise on neck pain, necks disability and neck length change of turtle neck syndrome patients but also to provide fundamental data for this field in the future. Number of 60 persons were selected by pre-test and divided to 21 persons in straight body exercise group, 19 persons in exercise group and 20 persons in control group(non-exercise group). 5 kinds of straight body exercise were applied in straight body exercise group, 8 kinds of strengthening cervical vertebral exercise were applied in exercise group and no exercise was applied in control group. Neck pain, necks disability index and neck length were measured before and after exercise and 10 weeks later as well. The data were analyzed by SPSS(v18.0). In straight body exercise group and exercise group, neck length, neck pain and necks disability index were significantly decreased after eight weeks of exercise and there was no significant difference in control group. Neck length which was checked every week in straight body exercise group and exercise group was significantly decreased and there were significant differences after 3 weeks.. After 2 weeks of 8 weeks exercise, neck length, neck pain and necks disability were checked again in post test and those results were maintained just like 8 weeks exercise status. As above results, it was more efficient in the straight body exercise group than exercise group and control group to decrease neck pain, necks disability and neck length of turtle neck syndrome patients. Furthermore, after 2 weeks of 8 weeks exercise, the results were maintained just like 8 weeks exercise status. Therefore, the author consider that straight body exercise will be effective exercise for turtle neck syndrome patients, and this study would provide fundamental data for this field in the future.

일반적으로 우리나라 수해는 미개수 하천 지역의 외수침수와 더불어 홍수유출 단면 부족 및 내수배제 불량 등이 주요 원인이지만 하천 내 주요 수공구조물인 교량이나 보 등에 의한 홍수위 상승으로 발생한다. 특히, 교량은 도로의 교통기능에 중점을 둔 설계와 시공으로 수리학적으로 매우 불리한 위치에 건설되기도 하며 기존 교량폭의 확장이나 인접한 위치에 다른 교량들을 추가로 건설하여 하천의 한정된 통수단면적이 점차적으로 감소하는 등 하천관리에 많은 어려움이 가중되고 있다. 따라서 본 연구에서는 FLUMEN 모형을 이용하여 교량이 홍수위 상승 및 홍수범람에 미치는 영향과 이에 따른 제외지 침수면적의 변화를 파악하였다. 감천과 직지사천이 합류되는 구간을 대상으로 지형자료는 총 7곳의 교량을 고려하여 구축한 후 교량 유 무에 따른 조건별 부정류 모의를 실시하였다. 모형의 적용 결과 교량 건설에 따른 하폭 감소율은 김천철교 지점에서 10.92%로 가장 컸으며, 수위는 김천대교 지점에서 0.15m로 가장 크게 상승하였다. 또한 경부고속국도 주변의 수위는 경부고속철도 교량의 신설로 인해 140%까지 증가하는 것으로 나타났다. 홍수범람 모의 결과 교량 건설 전과 후에 제방 월류에 의한 침수가 발생하였고 교량 건설 후 범람면적과 침수심이 증가하였으며, 홍수범람의 주원인은 하천의 통수단면적이 작기 때문으로 나타났다.

Descending nectorizing mediastinitis (DNM). represents a virulent form of mediastinal infection requiring prompt diagnosis and treatment to reduce the high morbidity mortality associated with this disease. Intr. avenous broad-spectrum antibiotic therapy alone is not efficient without adequate surgical drainage of the cervical and mediastinal collections, extensive debridement and excision of necrotic tissue, and wide mediastino-pleural irrigation. A 38-year-old man admitted via emergency room with painful left neck swelling and uncontrolled high fever. Chest computed tomogram showed left paratracheal abscess descending into the superior and anterior mediastinum. Transcervical mediastinal drainage was performed with 26 Fr. chest tube and left paratracheal drainage was performed with Penrose drain in urgency. Culture and sensitivity test grew Yeast. The drains removed via gradually shortening on day 39 after surgery.

Lamierre's syndrome is characterized by a rare fulminant condition resulting from primary oropharyngeal infection followed by secondary septic thrombophlebitis of the internal jugular vein and metastatic infection. A forty-year-old man who had been on ventilator due to servere chest trauma, showed severe reddish inflammatory swelling of the right cervical soft tissue and newly developed pneumonia. He went into in septic condition shortly thereafter. Thrombophlebitis with central abscess in the right internal jugular vein was identified by neck CT and MRA(magnetic resonance angiography). Right cervical swelling worsened in spite of clindamycin and heparin therapy. We performed immediate surgery for removal of septic thrombus and resection of internal jugular vein. Patient's septic condition, pneumonia, and local inflammatory reaction were improved within several days after surgery.

Microvascular tissue transfers have facilitated primary closure of various complex defects after radical ablation of head and neck cancers. From Oct 1991 to Feb 1992, we used forearm free flap in two patients and delto-pectoral flap in one patient who had preoperative irradiation for pharyngoesophageal reconstruction. The stricture and fistular formation were most troublesome complication in forearm free flap, so we designed as lazy S shape in distal flap margin to prevent circular contraction and longitudinal margin was deepithelized(5mm) and sutured double layer to withstand fistular formation and this can be considered useful in place of a free jejunal transfer.
