Objective To explore the efifcacy and safety of cryotherapy combined with argon plasma coagulation under bronchoscope for the treatment of airway stenosis. Methods The application of cryotherapy combined with argon plasma coagulation under bronchoscope in 26 patients with airway stenosis. Cryotherapy and argon plasma coagulation were taken turns during therapy. Larger lesions needed to be operated fractionally. The efficacy and safety of above treatments were evaluated after one week. Results Among twenty-six patients included 2 cases of tracheal carcinoma, 15 cases of lung cancer, 8 cases of endobronchial tuberculosis and 1 case of begin granulation. The frequencies of treatments during twenty-six patients were 41 times. 10 cases were complete response (38.5%), 15 cases were part response (57.7%), 1 case of mild response (3.8%). The overall effective rate was 96.2%. Conclusion Cryotherapy combined with argon plasma coagulation under bronchoscope for the treatment of airway stenosis are more efifcacy and safety for relieving symptoms.%目的：探讨支气管镜下冷冻联合氩等离子电凝术治疗气道狭窄的有效性和安全性。方法选取弋矶山医院26例气道狭窄患者，应用冷冻联合氩等离子凝固术治疗。术中采用冷冻、氩等离子电凝、冻切重复进行。对于较大的病变可分次手术.全部治疗结束l周后评价疗效。结果26例患者，其中2例气管癌、肺癌15例、支气管内膜结核8例、良性肉芽1例。共接受治疗41次。完全有效10例(38.5%)，部分有效15例(57.7%)，轻度有效1例(3.8%)，临床有效率96.2%。结论在局麻下采用冷冻联合氩等离子电凝治疗气道狭窄疗效满意，可有效缓解症状，安全性较高。
