Hypopharyngeal carcinoma is an aggressive malignancy that usually presents at a late stage, thereby resulting in an overall poor prognosis fir these unfortunate patients. The most effective treatment of pyriform sinus carcinoma combines surgery and radiation. Total laryngopharyngectomy is necessary in advanced tumors, but may not be appropriate in limited lesions. Therefore several procedure for partial laryngopharyngectomy have been proposed. Supracricoid hemilaryngopharyngectomy is the one of these procedure. This report presents one case of supracricoid hemilaryngopharyngectomy in a patient with pyriform sinus medial wall cancer and analyses aerodynamic study before and after operation.

Pharyngocutaneous fistula is one of the most common wound complications after total laryngectomy. The leakage of saliva may cause an erosion of greater vessels nearby and result in a life-threatening bleeding. 65-year-old male received laryngectomy and pharyngectomy followed by Latissimus dorsi flap reconstruction due to recurred laryngeal cancer with oropharyngeal extension after postoperative radiotherapy. Pharyngeal fistula was developed and an excessive fresh blood flowed through the oral and nasal cavity. The patient was transferred to the operating room immediately, and the causing artery was ligated. The rupture of the common carotid artery and its branches should be warned when the pharyngocutaneous fistula is developed. Prompt and proper therapy must be performed for the patients with impending or acute hemorrhage.

Purpose: Various attempts of reconstruction for pharyngoesophageal defects after ablative surgery have been made to restore the function of the pharyngoesophagus. A fabricated tubed radial forearm free flap or free jejunal free flap was used when the width of remnant pharyngeal wall was less than 50% of the normal width. However there are many disadvantages such as stricture, saliva leakage and fistula formation on tubed radial forearm free flap. The jejunal free flap has the problem such as short pedicle, poor tolerance of ischemic time, wet voice and delayed transit of swallowed food due to the uncoordinated contraction. The authors studied the utility of patch-type radial forearm free flap using the remnant posterior pharyngeal wall of the hypopharynx. Methods: Retrospective reviews in Severance Hospital were made on 25 patients who underwent reconstruction surgery with patched radial forearm free flap because of the hypopharyngeal cancer between 1996 and 2005. The patients of Group I had the narrow posterior pharyngeal wall and its width was less than 3centimeters after the tumor was resected. Those of Group II had the partial pharyngectomy and the width of the remnant pharynx was larger than 3 centimeters. Results: Seven patients belonged to the group I and the flap of this group had 100% survival rate. One case of fistula and no swallowing discomfort due to stricture was reported. The Group II including 18 patients also had the 100% flap survival rate. Neither fistula nor stricture was seen but the lower diet grade was checked. Conclusion: The patch type radial forearm free flap using the remnant pharyngeal wall have the advantage of the radial forearm free flap, and furthermore this flap is the safe reconstructive method even if the width of the remnant pharyngeal wall is less than 30% of that of normal pharynx.

목적: 하인두암의 치료에서 수술 후 방사선치료에 대한 치료결과 분석을 통하여 그 임상적 의의와 한계를 알아보고, 방사선치료와 관련된 예후인자들을 확인하여 향후 새로운 치료방침을 세우는데 기본 자료를 마련하고자 연구를 시행하였다. 대상 및 방법: 1988년부터 1999년까지 부산대학교병원에서 원발성 하인두 편평상피세포암으로 진단되어 수술 후 방사선치료를 시행받은 64명을 대상으로 후향적 분석을 실시하였다. 모든 환자들은 근치적 목적의 종양절제술을 시행한 뒤에 통상적인 분할조사법을 이용하여 원발 부위와 경부 림프절 부위에 수술 후 방사선치료를 실시하였다. 결과: 5년간의 전체 생존율과 질병 관련 생존율은 각각 42.2%42.2%와 51.6%였고, 병기별 5년간 질병 관련 생존율은 Stage I, II, III, IV에서 각각 100%, 80%, 62.5%, 41.5%였다. 예후인자에 대한 단변랑 분석에서 전체 병기, T 병기 및 N 병기, 2차성 원발암 발생 유무, 절제연 침범 여부, 림프절의 외막 침범 여부, 총 방사선량 등이 의미가 있었으며, 다변량 분석에서는 T 병기 및 N 병기, 절제연 침범 여부, 림프절 외막 침범 여부 등이 유의한 예후인자로 판명 되었다. 결론: 절제 가능한 하인두암 환자에서 수술 및 보조적 방사선치료는 후두나 인두의 기능장애 가능성에도 불구하고 생존율이나 국소 제어율 면에서 좋은 치료 결과를 보였다 그러나 상당히 진행된 하인두암의 치료에서는 국소제어나 환자의 삶의 질과 관련하여 기존의 수술 및 방사선 병합치료의 한계를 확인할 수 있었는데, 최근 연구되고 있는 화학-방사선 병합요법이나 세기조절 방사선치료 등과의 비교 연구가 예후인자 관련 연구와 동반해서 진행되어야 할 것이다.
