비·부비동 악성종양의 내시경하 절제술

Background and Objectives: Since introduction of nasal endoscope to treat chronic sinusitis, its use has been extended to a variety of sinonasal disease. Although the endoscopic technique has some limitation, the role of nasal endoscope for resection of sinonasal malignancies has increased these days. The purpose of this study is to evaluate the treatment results of endoscopically managed sinonasal malignant tumors. Subjects and Methods: Medical records of twelve patients with sinonasal malignant tumor who were treated with only endoscopic technique between 1991 and 2003 were retrospectively reviewed. The study group consisted of six men and six women ranging in age from 24 to 77 years with mean age of 50.9 years. Results: Follow-up ranged from 28 to 93 months (mean 61.1 months). Combined radiotherapy with or without chemotherapy was given to all patients except one with squamous cell carcinoma combined with inverted papilloma. Four cases had recurrence. Three patients had local recurrence and, after treatment, they have been disease free now for more than four years. One patient with a malignant melanoma died of distant metastasis at postoperative ten months. Overall survival rates were 91.6% and disease free survival rates were 91.6%. Conclusion: Endoscopic resection of sinonasal malignant neoplasm may be considered an alternative to traditional approaches in carefully selected patient with several advantages including excellent illumination, maximal preservation of uninvolved vital structures and sparing of facial incision.
