비·부비동 악성종양에서 순수 내시경 절제술과 내시경절제술과외부접근법을 병용한 환자의 치료성적 비교

Background and Objective: The aim of this study was to evaluate the treatment outcomes according to the surgical approach, which included the the strictly endoscopic surgery (ESS) and the endoscopic assisted external approach (ESS with EA) of the sinonasal malignancies. Materials and Methods: Retrospective chart analysis was conducted to the patients with malignant sinonasal tumors between January 1995 and June 2008. Demographics, histology, primary sites, tumor stages, surgical management, adjunctive treatment, local recurrences, overall and disease free survivals were analyzed. Results: Forty-one patients were identified (21 men and 20 women). The mean age was 56.8 years, and the mean follow-up was 45.3 months. twenty-five patients were managed with ESS, and 16 patients were treated with ESS with EA. Local recurrence was observed in 4/25 (16%) and 5/16 (31.3%) of the patients in each ESS and ESS with EA group. Overall survival rates in ESS and ESS with EA group were 96% and 87.5%, respectively. Disease free survival rates in ESS and ESS with EA group were 91.7% and 85.7%, respectively. No significant difference was observed between groups on survival rates. Conclusions: Strictly endoscopic surgery or endoscopic assisted external approaches may be alternative options for carefully selected sinonasal malignant tumors according to the tumor origin and extent.
