目的：探讨内镜微波技术治疗鼻咽癌鼻咽腔内复发的疗效和实用价值。方法：在鼻咽内窥镜引导下，先将鼻咽局部肿瘤尽量摘除，再引入微波手术器，将微波针状辐射天线插入肿瘤组织四周，连同其周围部分正常组织进行凝固治疗。结果：本组复发癌27例，除4例于3年内肿瘤再复发外，其余23例均临床治愈。生存5、4、3、2、1年分别为2、2、6、6、7例。结论：本疗法适应证与鼻咽肿瘤切除术相同，但操作简便易行，疗效较理想，可视为一种非开放性手术疗法，其在复发鼻咽癌治疗上，具有一定的可行性及临床应用意义。
Objective: To investigate the efficacy and practical value of endoscopic microwave technique in the treatment of nasopharyngeal carcinoma recurrence. Methods: Under the guidance of nasopharyngeal endoscope, nasopharyngeal local tumor should be removed as far as possible, and then a microwave surgical instrument was introduced. The microwave acicular radiating antenna was inserted into the surrounding of the tumor and coagulated with some normal tissues around it. Results: 27 cases of recurrent cancer in this group, in addition to 4 cases of tumor recurrence within 3 years, the remaining 23 cases were clinically cured. Survival 5, 4, 3, 2, 1 year were 2,2,6,6,7 cases. Conclusion: The indications for this therapy are the same as nasopharyngectomy, but its operation is simple and easy. The curative effect is ideal and it can be regarded as a kind of non-open surgical treatment. It has certain feasibility in the treatment of recurrent nasopharyngeal carcinoma. Clinical significance.
