目的 探究微波在鼻内镜手术治疗鼻腔鼻窦内翻性乳头状瘤中的应用效果。方法 对照组予以单纯鼻内镜手术治疗， 观察组在此基础上予以微波治疗，术后观察对比两组复发率及肿瘤恶变率。结果 观察组术后复发率为7.3%，明显 低于对照组的36.5%，P＜0.05；观察组未发生肿瘤恶变，对照组肿瘤恶变率为5.8%，组间比较有统计学意义，P ＜0.05。结论 鼻内镜联合微波治疗鼻腔鼻窦内翻性乳头状瘤的临床疗效确切，有助于降低术后复发率和恶变率。

Objective To explore the microwave in endoscopic sinus surgery for inverted papilloma of the effect of nasal application. Methods The control group was treated with endoscopic surgery alone, the observation group to be microwave treatment on this basis, comparing the two groups were observed recurrence rate and the rate of malignant tumors. Results The recurrence rate was 7.3%, significantly lower than the 36.5% in the control group, P<0.05. observation group did not occur malignant tumor, malignant tumor in the control group was 5.8%, was statistically significant between the two groups, P<0.05. Conclusion Nasal endoscopy and clinical efficacy of microwave treatment of nasal inverted papilloma exact, help to reduce the recurrence rate and the rate of malignant transformation.
