objective to radiofrequency ablation in treatment of the clinical effect of laryngeal stenosis in elderly postoperative laryngeal cancer were analyzed. Methods in our hospital for the treatment of elderly patients with laryngeal stenosis in 60 cases, were randomly divided into observation group and control group, each of 30 cases, observation group were given radiofrequency ablation treatment. The control group was given laser treatment. To compare the efficacy of two groups of the total efficiency and the number of patients with painless pain patients. Results the total effective rate of observation group (89.63%) was higher than the control group in the total efficiency (65.31%), the observation group the pain degree of pain degree is lower than the control group, two groups of comparison, The difference was statistically significant (P<0.05). Conclusion low temperature plasma radiofrequency ablation is an ideal method for the treatment of laryngeal stenosis in elderly patients with laryngeal cancer. It is worthy of popularization and Application
