비강 및 부비동 악성종양의 내시경적 절제술 = Endoscopic Resection of Sinonasal Malignant Tumors

다국어 초록 (Multilingual Abstract)

Background and Objectives：Endoscopic surgery largely replaced the traditional external aproach in the treatment of sinonasal inflamatory diseases and most benign tumors. However, there is much debate about its aplicability to resection of sinosal sinonasal malignant tumors. Subjects and Method：We retrospectively reviewed the medical records and radiologic findings of 1 patients who had underwent transnasal endoscopic excision for sinonasal malignancy from 1998 to 2003. Al patients were treated with curative intent. Results：The mean age was 60.6 (31-75 years) years and the mean folow-up period was 69 months (52-112 months)(4 cases), plasmacytoma (2 cases), adenoid cystic carcinoma, olfactory neuroblastoma, cylindrical cel carcinoma, squamous cell carcinoma and neuroendocrine carcinoma. In ten cases, the tumor was removed by transnasal endoscopic excision with ade-quate free margin of normal mucosa. In one case, Caldwel-Luc operation was combined with the endoscopic excision. During the folow-up, only one case of malignant melanoma had recured at the lateral neck and retropharyngeal lymph node, but the Conclusion：Considering oncological results and surgery-related morbidities, transnasal endoscopic resection can be used as a good modality in the highly selected early T stage of sinonasal malignancies.
