The anterior mediastinal tracheotomy(AMT) facilitates resection of stomal recurrence after total laryngectomy and tumors involving the cervicothoracic trachea and esophagus. An 81-year-old-man came to our clinic due to the progressive dyspnea during three months. He received the total laryngectomy five years ago. We diagnosed as Sisson type I stomal recurrence and then performed the wide excision, both selective neck dissection, sternal manubrium resection and AMT. Before surgery, we planned the pectoralis major myocutaneous flap. Unluckily we could not fulfill this procedure because of patient's medical status during anesthesia. The tracheocutaneous fistula was observed in the second postoperative day. He expired due to the huge bleeding from the wound. When AMT is performed, exact manipulation of major vessels and adequate flap are mandatory these elevate the feasibility of AMT.

Background: We peformed a retroslective study in patients with previously untreated advanced (Stage III or IV) laryngeal and hypopharyngeal cancer to compare the results of induction chemotherapy followed by definitive radiation therapy (CT+ RT) with those of conventional laryngectomy and postoperative radiation therapy (OP + RT). Method: Between 1985 and 1990, twenty-four patients were treated with two or three courses of chemotherapy and radiation therapy (66-75 Gy). Twenty-five patients were received laryngectomy and radical neck dissection (except 3 patients) and postoperative radiation therapy (55~64 Gy). Result: After a median fellow-up of 20 months, the actusrial 5-year overall survival rate was $24\%$ (chemotherapy group) and $36\%,$ (op group). (P>0.1). The local control rate was the $65\%,$ (13/20) and $68.2\%,$ (15/22). (p>0.1). The rate of laryngeal preservation was $65\%$ (13/20) in chemotherapy group. Conclusion: Induction chemotherapy and definitive radiation therapy can be effective in preserving the larynx in a high percentage of patients with advanced laryngeal and hypopharyngeal cancer.

Pharyngocutaneous fistula is a relatively common, but serious complication after pharyngeal or laryngeal cancer surgery. It can cause wound infection, longer hospitalization period and sometimes carotid artery rupture which can be fatal. Recently, we experienced a 63-year-old larynx cancer patient who had dementia and alcoholic liver cirrhosis for underlying diseases. He underwent total laryngectomy and both neck dissection, and pharyngocutaneous fistula occurred during postoperative radiotherapy. Pharyngocutaneous fistula during postoperative radiotherapy has not yet reported in the literature, and there are few reports about pre and postoperative management of dementia patient after head and neck cancer surgery. Therefore, we report this case with a brief review of literature.

Laryngeal lymphoepithelial carcinoma (LEC) is a rare tumor with only 34 cases in the published literature. Epidemiologically, laryngeal LEC is extremely rare in Asian. Originally, LEC is a common type of carcinoma in nasopharynx. Laryngeal LEC resembles nasopharyngeal LEC, except that most cases of laryngeal LEC are not associated with Epstein-Barr virus. We present a case of laryngeal LEC which developed at the left false cord extending to true vocal cord, para-glottic space and pre-epiglottic space. Total laryngectomy with bilateral neck dissection was performed. LEC was reported as biopsy confirmation result. The patient underwent postoperative radiotherapy and showed no evidence of recurrence during follow-up period of 42 months. In consideration that LEC in larynx have not been reported in South Korea yet, we introduce the clinical features and treatment outcomes of laryngeal LEC with literature review.

Persistent pharygoesophageal spasm has been demonstrated to be responsible for poor speech rehabilitation after laryngectomy Management of these patients has included bougienage and pharyngeal neurectomy. Achalasia is a disorder of swallowing in which the lower esophageal sphincter fails to relax. Botulinum toxin injection of the upper esophageal sphincter or lower esophageal sphincter has been successfully used diagnostically and therapeutically for esophageal speech failure or achalasia. So, we report the use of botulinum toxin, a paralytic agent, for the treatment of these conditions.

Objectives: Despite various attempts to preserve the normal voice in advanced laryngeal cancer, it is inevitable for many advanced laryngeal cancer patients to undergo total laryngectomy and thus making a trade off between quality and quantity of life. Laryngectomees are faced with voice loss, change in physical appearance and health deterioration which hinder their efforts to rehabilitate back into their family and employment leading to poor quality of life. The objectives of this study were to evaluate the quality of life in long term surviving laryngectomees to, define the factors which are most important in determining their present quality of life and to propose a theoretical model for quality of life after laryngectomy in Korea. Materials and Methods: From 1986 to 1995, 120 laryngectomees with no evidence of disease were followed up for at least 3years were evaluated. Each of 15 quality of life domains with a total of ten points were given for a quality of life score. Results: There was no significant difference in the physical-mental adaptation index such as general health and mental health between the laryngectomees and control group(p>0.05). However, social adaptation index such as social activity, occupational status and economic status for laryngectomees were significantly lower with 2.3, 3.5, and 4.4 points compared to control group with 8.5, 7.6, and 7.1 points respectively(p<0.05). Conclusion : Vocational and social rehabilitation should be emphasized with highest priority for improving their economic status and thus improving their quality of life.

This study is limited to epidermoid carcinoma arising in the larynx. The 623 patients in this series comprised 1.6% of all malignant neoplasms seen during the 20-year period .from 1965 to 1984 ; it comprised 13.2% of all cancers of the head and neck registered during this period. The male: female ratio was 11:1, and the highest incidence was in the fifth decade of life. Analysis by anatomical site revealed that 51.7% were supraglottic, 36.1% glottic, and 6.8% subglottic in oriain. One-hundred eighty-nine(79%) were clinically Stage III or Stage IV lesions at the time of the first visit. Of the total of 263 cases, 113 refused treatment, 4 definite radiation for $T_1$. lesion,21 underwent palliative therapy only, and 125 underwent surgical management with intent to cure. This surgical category included 53 patients who had surgical treatment only and 72 who underwent combined therapy(preoperative radiation, postoperative radiation, or inductive chemotherapy followed by surgery and postoperative radiation). The surgical management varied from partial laryngectomy to widefield laryngectomy and ipsilateral neck dissection. In 14.4% pathologically positive node or nodes were found in the clinically negative contralateral neck nedes. Such contralateral spread was most common in supraglottic site of origin(222%). Combined modality of management was compared to single therapy. Although results at three years showed no difference in determinate disease-free survival between patients treated by surgery only and those treated by surgery followed by postoperative radiation therapy at 5 years a statistically significant difference emerged, only 36% of those receiving surgery alone surviving as compared to 65.4% in the surgery with radiation group.

We report 22 cases of well -differentiated thyroid carcinoma infiltrating the upper airway tract. This retrospective study was undertaken to evaluate the prognosis md to determine optimal therapy for thyroid carcinoma adhering to or invading the trachea or larynx from 1984.3 to 1996.12. The treatment was individualized depending on the extent of the cancer. There were 12 cases dissected free by an laryngotracheal shaving, 7 cases removed by an tracheal resection with end to end anastomosis, 3 cases removed by an total laryngectomy. In all of these cases, we performed a total thyroidectomy with an accompanying neck dissection. There were no major complications during the operation. Over the 5-years observation period, 11 patients are alive without a sign of recurrence, 4 Patients are alive with recurrence, 7 died of thyroid carcinoma; 2 of 12 in an laryngotracheal shaving cases, 2 of 7 in an tracheal resection with end to end anastomosis case, 3 of 3 in an total laryngectomy case. The result showed an radical operation for thyroid carcinoma invading the laryngotrachea improves the survival rate, but limits improving the cure rate, and the invasion of the thrchea or larynx must be treated whenever possible by an total resection followed by radioiodine and external beam radiation.
