中文摘要：

目的：总结鼻内镜下低温等离子射频切除鼻腔良性肿瘤的疗效。方法回顾性分析2012年1月至2013年5月诊治并完成1年随访的17例鼻腔鼻窦良性肿瘤患者的临床资料。患者均在鼻内镜下应用低温等离子射频实施手术，其中内翻性乳头状瘤8例，鼻咽纤维血管瘤1例，鼻腔血管瘤3例，上颌窦出血坏死性息肉5例。结果术中出血量为5～150 mL，中位数为30 mL。手术时间为20～55 min，中位数为35 mim。术后2个月术腔上皮化良好，无出血、鼻腔干燥等并发症。随访1年未见复发。结论鼻内镜下低温等离子射频手术治疗鼻腔鼻窦良性肿瘤具有出血少、损伤小、手术时间短等优点。

英文摘要：

Objective To evaluate the effect of nasal endoscopic surgery by low-temperature plasma radiofrequency for benign tumor resection.Methods The clinical data of 17 patients with nasal sinus benign tumor treated between Janu-ary 2012 and May 2013 under nasal endoscopic surgery by the low-temperature plasma radiofrequency were retrospec-tively studied.All were followed up in a 1-year process.In which,8 cases of inverted papilloma,1 case of angiofibro-ma of nasopharynx,3 cases of nasal hemangioma,and 5 cases of hermorrhagic and necrotic polyps of maxillary sinus were studied.Results The blood loss was 5 to 150 mL with an average of 30 mL.The operation time was 20 to 55 minutes with an average of 35 minutes. During the follow-up period,cavity epithelial change was good and no recur-rence was found.Conclusion Endoscopic surgery by low-temperature plasma radiofrequency is a viable surgical meth-od for benign tumor and has advantages of less bleeding,minimal invasion and short operation time.
